72 amps and DACs made our rankings with balanced outputs, either a 4.4 mm or XLR headphone jack or balanced XLR line outputs. Balanced headphone outputs usually deliver more power into demanding headphones, and balanced line outputs suit studio monitors and amplifiers with XLR inputs. Every one is rated from its SINAD as measured by Audio Science Review plus its rated output power, so a higher rating means a cleaner, more capable unit rather than a longer feature list.
This is every match, grouped by type and sorted by rating.

USB-C Dongle DACs
Ranked #1 of 14 in USB-C Dongle DACs - FiiO KA15: $99.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 115 dB, so its noise and distortion are inaudible. Its rated 560 mW into 32 ohms from the balanced output in desktop mode is unusually strong for a dongle, enough for most full-size headphones. It adds a 10-band parametric EQ, a 4.4 mm balanced jack and a coaxial digital output, and it rates higher than the Fosi Audio DS3 for the same price.
Cons: The headline power figure needs the balanced output in desktop mode, and it falls to 78 mW into 300 ohms, so high-impedance headphones may run short. The TRN Black Pearl measures slightly cleaner for much less. Volume is set with buttons rather than a knob.

Ranked #2 of 14 in USB-C Dongle DACs - E1DA 9039S: $139.00 Linsoul eBay
Pros: Audio Science Review measured a SINAD of 125 dB, so its noise and distortion are inaudible, even with sensitive in-ears. E1DA rates it at 400 mW into 32 ohms balanced, enough for most headphones from a 10 g USB-C dongle with dual ES9039Q2M chips.
Cons: Its only headphone output is a 2.5 mm balanced jack, so most headphones need an adapter or a new cable. The FiiO KA15 rates higher with more balanced power for less.

Ranked #3 of 14 in USB-C Dongle DACs - TRN Black Pearl: $35.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 117 dB, so its noise and distortion are inaudible. A rated 320 mW into 32 ohms from its 4.4 mm balanced output drives most headphones, and it adds a 3.5 mm output and an 8 band EQ app. It rates higher than the Chord Mojo 2 for a small fraction of the price.
Cons: It only takes USB-C input, with no optical, coaxial or Bluetooth. The FiiO KA15 rates higher and is rated for more balanced power, though it costs more.

Ranked #4 of 14 in USB-C Dongle DACs - Fosi Audio DS3: $99.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. A 32-band parametric EQ gives unusually fine tuning control for a dongle, and it offers both 3.5 mm and 4.4 mm balanced outputs. At 16 g and 55 mm long, it is very light to carry.
Cons: Its rated 220 mW into 32 ohms drives most headphones but leaves less headroom than the FiiO KA15, which costs the same and rates higher. The TRN Black Pearl also rates higher and measures slightly cleaner for much less. Volume is button controlled.

Ranked #5 of 14 in USB-C Dongle DACs - TANCHJIM Space: $89.99 HiFiGo eBay
Pros: Audio Science Review measured 115 dB SINAD, right at the level where noise and distortion become inaudible, so this dongle is effectively transparent. A rated 230 mW into 32 ohms drives most headphones, and it offers both a 3.5 mm jack and a 4.4 mm balanced output with dual CS43131 DAC chips. Button volume control lets you adjust level on the dongle itself.
Cons: It rates below the FiiO KA15 for a similar price, and that rival publishes more than twice the power from its balanced output. The TRN Black Pearl rates higher and measured cleaner for much less. The 230 mW figure suits most headphones but leaves little headroom for hard to drive planar magnetic models.

Ranked #6 of 14 in USB-C Dongle DACs - TempoTec Sonata BHD Pro: $69.90 Amazon eBay
Pros: Audio Science Review measured a SINAD of 112 dB, clean for nearly all listening. A rated 280 mW into 32 ohms from the 4.4 mm balanced output drives most headphones, and a 3.5 mm output is also included. At 18 g it is easy to keep attached to a phone, and it costs less than the Fosi Audio DS3.
Cons: Its SINAD is lower than most rivals here, and the TRN Black Pearl rates higher with 117 dB and more rated power for less. There is no EQ listed and volume is button controlled. The rated power figure applies to the balanced output only.

Ranked #7 of 14 in USB-C Dongle DACs - Fosi Audio DS2: $59.99 Amazon eBay
Pros: Audio Science Review measured 117 dB SINAD, so its noise and distortion are transparent. It offers both a 3.5 mm jack and a 4.4 mm balanced output, with physical volume buttons, from a USB-C dongle. It rates higher than the FiiO KA11 and JCALLY JM20MAX.
Cons: A rated 170 mW into 32 ohms, and only from the balanced output, drives most headphones but leaves little headroom for planar magnetics. The TRN Black Pearl rates higher with more balanced power and the same SINAD for less, and at 91 g it is heavy for a dongle.

Pros: Audio Science Review measured a SINAD of 104 dB, which is clean for nearly all listening. It offers both a 3.5 mm output and a 4.4 mm balanced output in a light 38 g body with button volume control.
Cons: Fosi Audio doesn’t publish a 32 ohm power figure, so it is hard to know which headphones it can drive well. It rates lower than the Fosi Audio DS2, which costs about the same and measured transparent at 117 dB, and the FiiO KA11 rates higher for less.

DAC and Headphone Amp Combos
Ranked #1 of 43 in DAC and Headphone Amp Combos - SMSL DO400: $499.00 Amazon eBay
Pros: Audio Science Review measured 123 dB SINAD, so its noise and distortion are transparent. A rated 3 W into 32 ohms and 700 mW into 300 ohms drives nearly any headphone, through 6.35 mm, 4.4 mm or 4-pin XLR outputs. Inputs cover USB, optical, coaxial, AES/EBU, I2S and LDAC Bluetooth, with RCA and XLR outputs for powered speakers.
Cons: It costs more than the D&A Alpha and SMSL RAW-MDA1, which share its rating and also measure transparent. At 1,450 g it is a full size desktop unit.

Ranked #2 of 43 in DAC and Headphone Amp Combos - D&A Alpha: $399.00 Amazon eBay
Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are transparent. A rated 9 W balanced into 32 ohms and 1.1 W into 300 ohms is enough for nearly any headphone, planar magnetics included, and it adds optical, coaxial and LDAC Bluetooth inputs with XLR line outputs for powered speakers. It matches the rating of the SMSL DO400 for less.
Cons: It is a large, heavy desktop box at 1,650 g, so it is no fit for a cramped desk or travel. The Topping DX5 II rates the same with similarly huge balanced power for less, and the 9 W figure applies only to the 4.4 mm balanced output.

Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are transparent. A rated 1.7 W into 32 ohms drives nearly any headphone including planar magnetics, and it has two optical and two coaxial inputs plus USB and LDAC Bluetooth. It matches the rating of the SMSL DO400 for much less.
Cons: The maker doesn’t publish a 300 ohm power figure. Bluetooth lacks AAC, and the Topping DX1 II rates the same with ample balanced power for far less if you don’t need its extra inputs.

Ranked #4 of 43 in DAC and Headphone Amp Combos - Topping DX5 II: $299.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 122 dB, so its noise and distortion are inaudible. A rated 6.4 W into 32 ohms and 990 mW into 300 ohms is enough for nearly any headphone, through 6.35 mm, 4.4 mm and 4 pin XLR outputs. It adds a 10 band parametric EQ, Bluetooth with LDAC and aptX Adaptive, and RCA and XLR line outputs, matching the rating of the SMSL DO400 for less.
Cons: The Topping DX1 II shares its rating for well under half the price and still delivers about 1 W into 32 ohms, which is plenty for most headphones. Its full size chassis takes more desk space than compact all in ones.

Ranked #5 of 43 in DAC and Headphone Amp Combos - D&A Alpha Pro: $699.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. A rated 6,000 mW into 32 ohms and 700 mW into 300 ohms will drive nearly any headphone, including demanding planars, through 6.35 mm, 4.4 mm balanced or 4-pin XLR outputs. It doubles as a full desktop hub with USB, optical, coaxial, RCA and Bluetooth inputs (LDAC, aptX HD, AAC) plus RCA and XLR outputs.
Cons: It costs far more than the Topping DX1 II, which rates the same and measures the same 121 dB SINAD. The SMSL DO400 also matches its rating for less while measuring slightly cleaner. At 1,760 g and 225 mm wide, it needs real desk space.

Ranked #6 of 43 in DAC and Headphone Amp Combos - Topping DX1 II: $119.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. A rated 1,000 mW into 32 ohms from the 4.4 mm balanced output handles most planar magnetic headphones, and a 10-band parametric EQ and a 3.5 mm headset jack with mic support are included. It rates the same as the D&A Alpha Pro for a fraction of the cost.
Cons: Inputs are limited to USB-C and optical, with no coaxial or Bluetooth. Its 230 mW into 300 ohms is modest beside the Topping DX5 II, which rates the same with far more power but costs more. No volume knob is listed.

Ranked #7 of 43 in DAC and Headphone Amp Combos - Topping G5: $299.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 120 dB, so its noise and distortion are inaudible. A rated 1,200 mW into 32 ohms is unusual for a battery unit and handles most planars, with 3.5 mm and 4.4 mm balanced outputs. It runs about 9 hours on USB, 10 on Bluetooth with LDAC and aptX Adaptive, and 25 as an analog amp, and weighs 265 g.
Cons: Its 175 mW into 300 ohms limits headroom with high-impedance headphones. The Topping DX1 II rates the same and measures slightly cleaner for much less, though it is not portable. At 140 mm long and 18 mm thick, it suits a bag better than a pocket.

Ranked #8 of 43 in DAC and Headphone Amp Combos - SMSL DL100: $152.99 Apos Audio eBay
Pros: Audio Science Review measured 119 dB SINAD, so its noise and distortion are inaudible. A rated 1.5 W into 32 ohms handles most planar magnetic headphones, with 6.35 mm and 4.4 mm balanced outputs plus RCA and XLR line outs for powered speakers. Inputs include USB-C, optical, coaxial, HDMI ARC and Bluetooth with LDAC, aptX HD, aptX, AAC and SBC, and a remote controls volume.
Cons: The Topping DX5 II earns the same rating and publishes far more balanced power, though it costs more. The Topping DX1 II shares the same rating for less if you do not need the extra inputs. Its 1.5 W rating is enough for most headphones but short of the several watts some rivals offer.

Ranked #11 of 43 in DAC and Headphone Amp Combos - Aune X1s GT: $319.00 Aune official store eBay
Pros: Audio Science Review measured 114 dB SINAD, which keeps noise and distortion clean for nearly all listening. Aune rates it at 1,200 mW into 32 ohms from the 4.4 mm balanced jack, enough for most planar magnetic headphones, and it takes USB, optical and coaxial inputs plus an external 10 MHz clock. RCA line and preamp outputs let it feed powered speakers too.
Cons: It costs more than the Topping DX3 Pro+, which rates the same with higher measured SINAD and more rated power. The SMSL RAW-MDA1 rates higher for less, and there is no Bluetooth input.

Ranked #12 of 43 in DAC and Headphone Amp Combos - Fosi Audio ZH3: $199.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 113 dB, clean for nearly all listening. A rated 2,570 mW into 32 ohms from the balanced output handles most planar magnetic headphones, with 6.35 mm and 4.4 mm balanced jacks. USB, optical, coaxial and RCA inputs plus RCA and XLR outputs let it double as a preamp, and bass and treble controls are built in.
Cons: The Topping DX1 II rates higher and measures cleaner at 121 dB for less money, though with less rated power. It has no Bluetooth input, and its SINAD trails most of the top-rated units in this group.

Ranked #13 of 43 in DAC and Headphone Amp Combos - Benchmark DAC3 HGC: $2,399.00 Benchmark Media Systems eBay
Pros: Audio Science Review measured a SINAD of 112 dB, clean for nearly all listening. It has USB, two optical, two coaxial and two analog inputs, RCA and XLR outputs, and a motorized volume knob with remote control. Its headphone outputs are rated for 1,250 mW into 30 ohms, enough for most planar magnetic headphones.
Cons: It costs many times more than the Topping DX3 Pro+, which rates higher and measures cleaner. The two headphone jacks are both 6.35 mm, so there is no balanced headphone output.

Pros: Audio Science Review measured 112 dB SINAD, clean for nearly all listening. Yulong rates it at 3,000 mW into 32 ohms and 460 mW into 300 ohms from the balanced 4-pin XLR jack, enough for nearly any headphone, and it accepts USB, AES/EBU, coaxial and optical with RCA and XLR outputs.
Cons: The Fosi Audio ZH3 rates higher with slightly better measured SINAD for much less. It is a large, heavy 4 kg box with no Bluetooth input.

Ranked #15 of 43 in DAC and Headphone Amp Combos - SPL Phonitor x: $3,200.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 111 dB, clean for nearly all listening. It is rated for 1,000 mW into 32 ohms from the 6.35 mm jack and 700 mW from its 4-pin XLR balanced output, enough for most planar magnetic headphones. It adds XLR and RCA inputs and outputs, a motorized volume knob and a learnable IR remote.
Cons: Its USB, coaxial and optical inputs require an optional DAC module, so digital playback costs extra. It costs far more than the JDS Labs Element IV, which rates higher, measures cleaner and has more rated power.

Ranked #16 of 43 in DAC and Headphone Amp Combos - SMSL DS20: $189.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. A rated 500 mW into 32 ohms and 120 mW into 300 ohms drives most headphones, through 3.5 mm or 4.4 mm balanced outputs. At 17 mm thick and 275 g, it is slim enough to sit on a desk or travel in a bag.
Cons: It only accepts USB-C, with no optical, coaxial or Bluetooth input, and volume is set with buttons. The Topping DX1 II rates higher, measures cleaner and adds optical input for less. The Fosi Audio ZH3 offers far more rated power for a similar price.

Ranked #18 of 43 in DAC and Headphone Amp Combos - Chord DAVE: $14,900.00 Audio46 eBay
Pros: Audio Science Review measured a SINAD of 110 dB, so noise and distortion stay clean for nearly all listening. Chord rates it at 1,400 mW into 33 ohms, enough for most planar magnetic headphones, and it doubles as a full DAC preamp with USB, four coaxial, two optical and AES/EBU inputs plus RCA and XLR outputs. A remote and digital volume control make it easy to run as the hub of a desktop or speaker system.
Cons: It costs vastly more than the Fosi Audio ZH3, which rates higher and measured cleaner in Audio Science Review’s tests. Its only headphone jack is a single 6.35 mm socket with no balanced headphone output, and at 5 kg it is a large desktop unit.

Ranked #20 of 43 in DAC and Headphone Amp Combos - Tanchjim Luna: $118.99 Apos Audio eBay
Pros: Audio Science Review measured 116 dB SINAD, so its noise and distortion are inaudible. A rated 285 mW balanced into 32 ohms drives most headphones, and it has both a 3.5 mm jack and a 4.4 mm balanced output fed by dual CS43198 DAC chips. It rates on par with the Chord Mojo 2 and measured cleaner for far less.
Cons: Power drops to a rated 54 mW into 300 ohms, which is thin for high impedance headphones, and planar magnetic models may want more than 285 mW. USB-C is the only input, so there is no optical or Bluetooth. The Schiit Magni Unity with Mesh DAC rates higher and publishes far more power at 32 ohms, though it costs more.

It offers 3.5 mm and 4.4 mm balanced headphone outputs, RCA and balanced RCA line outputs, USB-C and coaxial inputs, and optional Bluetooth through an add-on dongle, and it rates higher than the Woo Audio WA11 Topaz for far less.
Cons: Khadas rates it at 211 mW into 32 ohms on the balanced output, enough for most headphones but short of what many planar magnetic models want. The Fosi Audio SK02 matches its rating with much more balanced power for less, and Bluetooth requires buying the separate dongle.

Audio Science Review measured a SINAD of 105 dB, clean for nearly all listening, and it rates higher than the pricier Fosi Audio K7. It also has USB and optical inputs plus line and optical outputs.
Cons: Its 105 dB SINAD trails rivals like the Fosi Audio K7 at 116 dB, though the difference is unlikely to matter for most listening. There is no Bluetooth or coaxial input and no RCA output for powered speakers, only a 3.5 mm line out.

Inputs include USB, I2S over HDMI, AES/EBU, coaxial and optical, with RCA and XLR line outputs and a 60 step relay volume control. Audio Science Review measured 103 dB SINAD, clean enough for nearly all listening.
Cons: Its 103 dB SINAD trails many cheaper rivals, and the Tanchjim Luna rates higher with cleaner measurements for a small fraction of the price. There is no Bluetooth input, and at 6 kg it is a very large and heavy unit for what it delivers.

Headphone outputs include 6.35 mm, 4.4 mm balanced and 4-pin XLR.
Cons: Luxsin doesn’t publish an output power figure into 32 ohms. It costs several times more than the Loxjie D40, which rates the same and measures slightly cleaner. Bluetooth tops out at AAC, and at 3,720 g and 300 mm wide it is large and heavy.

Ranked #35 of 43 in DAC and Headphone Amp Combos - xDuoo XA-10: $479.00 Amazon eBay
Pros: It is a very flexible DAC and amp with USB, optical, coaxial and Bluetooth inputs, and Bluetooth supports SBC, AAC, aptX, aptX LL, aptX HD and LDAC. A rated 4,000 mW into 32 ohms from the balanced outputs drives nearly any headphone, and it offers 6.35 mm, 4.4 mm and 4-pin XLR headphone jacks.
Cons: Audio Science Review measured a SINAD of 90 dB, which is fine for most headphones but may reveal hiss or noise with sensitive in-ear monitors. The Loxjie D40 rates higher and measures far cleaner for less. The rated power figure applies to the balanced outputs, so the 6.35 mm jack delivers less.

It is rated for 441 mW into 300 ohms, ample for high impedance headphones.
Cons: Benchmark does not publish a power figure into 32 ohms, so its output into low impedance planar magnetic headphones is unconfirmed. It costs far more than the JDS Labs Atom Amp 2, which rates higher with similar measured cleanliness. It has no built in DAC.

Ranked #1 of 30 in DACs - Topping D50 III: $229.00 Amazon eBay
Pros: Audio Science Review measured 123 dB SINAD, so its noise and distortion are transparent. It packs USB-C, optical, coaxial and LDAC Bluetooth inputs, a remote controlled volume, 10 band parametric EQ and balanced TRS outputs into a compact chassis for an amp or powered speakers. It matches the rating of the Topping D900 for a small fraction of the price.
Cons: Balanced output uses 6.35 mm TRS jacks rather than XLR, so XLR gear needs adapter cables. Bluetooth lacks aptX and AAC, offering only SBC and LDAC.

Ranked #2 of 30 in DACs - Topping D900: $1,799.00 Amazon eBay
Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are transparent. It has a huge input set, including USB, two optical, two coaxial, AES, I2S and Bluetooth with LDAC and aptX Adaptive, plus a volume knob, 10 band parametric EQ and an XLR preamp output for powered speakers.
Cons: The Topping D50 III matches its rating with slightly higher measured SINAD for a small fraction of the price. Outputs are XLR only with no RCA, and at 2,520 g it is a large unit.

Ranked #3 of 30 in DACs - SMSL SU-10: $899.99 HiFiGo eBay
Pros: Audio Science Review measured 124 dB SINAD, so its noise and distortion are inaudible. It takes USB, optical, coaxial, I2S, AES and Bluetooth with LDAC, aptX HD and AAC, feeds an amp or powered speakers through RCA or balanced XLR, and has a volume knob and IR remote.
Cons: It is a DAC only, so headphones need a separate amp. The SMSL D-6S rates the same with nearly identical measured SINAD for far less.

Ranked #5 of 30 in DACs - SMSL VMV D1se2: $719.99 HiFiGo eBay
Pros: Audio Science Review measured 123 dB SINAD, comfortably in the range where noise and distortion are inaudible. Inputs cover USB, I2S, coaxial, optical and Bluetooth with LDAC, aptX HD, aptX, AAC and SBC, and it feeds amps or powered speakers through RCA or balanced XLR outputs. A remote is included for volume control.
Cons: It is a DAC only, so you need a separate headphone amp or powered speakers. The SMSL D-6S earns the same rating with nearly identical measurements for far less, and the Topping D70 Pro SABRE matches its SINAD and also costs less.

Pros: Audio Science Review measured a SINAD of 123 dB, among the cleanest results available, so its noise and distortion are inaudible. It feeds powered speakers or an amp via RCA or balanced XLR, with a volume knob for direct control. Inputs include USB, optical, coaxial, AES and Bluetooth with LDAC, aptX Adaptive, aptX HD and AAC, and it costs less than the SMSL RAW Pro-DAC1 with the same SINAD.
Cons: The SMSL D-6S rates the same for far less, so the extra cost mostly buys inputs and features rather than audible gains. At 222 mm wide and 1,050 g, it needs a full-size spot on the desk or rack.

Pros: Audio Science Review measured a SINAD of 123 dB, so its noise and distortion are inaudible. It accepts USB, optical, coaxial, AES, I2S and Bluetooth with LDAC and aptX Adaptive, and drives an amp or powered speakers over RCA or balanced XLR. A volume knob and Bluetooth remote let it work as a preamp.
Cons: The Topping D70 Pro SABRE matches both its rating and its 123 dB SINAD for much less, and the SMSL D-6S matches its rating for a fraction of the price. It has no headphone output.

Ranked #8 of 30 in DACs - Gustard X18: $749.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 122 dB, so its noise and distortion are inaudible. It has nearly every input you could want, including USB, I2S over HDMI, AES/EBU, coaxial, optical and Bluetooth with LDAC and aptX HD. It feeds an amp or powered speakers through RCA or balanced XLR outputs, with a volume knob for direct control.
Cons: The Topping D70 Pro SABRE matches its rating and measured slightly cleaner for less, and the SMSL D-6S matches its rating for a fraction of the price. Its full width chassis takes up more desk space than compact DACs.

Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are transparent. It offers USB, optical, coaxial and LDAC Bluetooth inputs with RCA and XLR outputs for an amp or powered speakers. It matches the rating of the Topping D70 Pro SABRE for far less.
Cons: There is no volume control listed, so it relies on the amp or speakers downstream to set level. DACs such as the Topping D70 Pro SABRE measure a touch cleaner at 123 dB, though they cost far more and the difference is not audible.

Cons: It is a DAC only, so you need a separate headphone amp or powered speakers. The Topping D70 Pro SABRE earns the same rating and measured slightly cleaner for less, and the SMSL DO200 Pro matches its SINAD for much less. No volume control is listed, so it may not work as a preamp for active speakers.

Cons: It is the priciest DAC in its group yet only matches the rating of the SMSL D-6S, which costs a fraction as much and measured cleaner. The Topping D70 Pro SABRE also measured cleaner at 123 dB for much less. At 3.2 kg it is large and heavy.

Cons: Audio Science Review measured only 98 dB SINAD, far behind inexpensive DACs; that is fine for most systems but noise may show through very revealing gear. The SMSL SU-2 rates much higher and measures transparent at 123 dB for a small fraction of the price.

Ranked #29 of 30 in DACs - Wyred4Sound DAC-2v2 SE: $3,799 Wyred 4 Sound eBay
Pros: It has a wide range of inputs, including USB, two coaxial, two optical, AES/EBU and I2S over HDMI, and connects to an amp or powered speakers through RCA or balanced XLR. A defeatable digital volume control and remote let it act as a preamp.
Cons: Audio Science Review measured just 90 dB SINAD, far behind modern DACs, which leaves noise and distortion that sensitive systems may reveal. The SMSL PS200 PRO rates much higher with far better measured SINAD for a small fraction of the cost.

Ranked #30 of 30 in DACs - Sonnect SoundWire: $165.00 Sonnect eBay
Pros: It turns a USB-C phone or computer into a source with two transformer isolated XLR line outputs, which suits connecting directly to powered speakers, mixers or PA systems.
Cons: Audio Science Review measured a SINAD of 85 dB, a level of noise and distortion that is an audible weakness. It has no headphone output and no volume control of its own. The Samsung USB-C to 3.5mm Headphone Jack Adapter measures cleaner and rates higher for far less, although it lacks XLR outputs.
