This page ranks 43 combined DACs and headphone amplifiers, the one box solution for a desk. Each rating combines its SINAD as measured by Audio Science Review with its rated output power and a small credit for features like balanced outputs, Bluetooth and EQ. Past about 115 dB of SINAD the unit’s own noise and distortion are inaudible, so the top of the list is decided mostly by power and features. The best are at the top.

#1 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.

#2 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.

#3 SMSL RAW-MDA1: $279.99 Amazon eBay
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.

#4 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.

#5 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.

#6 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.

#7 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.

#8 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.

#9 JDS Labs Element IV: $549.00 JDS Labs eBay
Pros: Audio Science Review measured a SINAD of 118 dB, so the DAC and amp are transparent. A rated 3,200 mW into 32 ohms drives nearly any headphone, and a built in 12 band parametric equalizer lets you correct headphone response without software. It takes USB-C and optical inputs and has RCA outputs for powered speakers.
Cons: It has no balanced headphone output, and the 4.4 mm jack is only available as a build option replacing the 6.35 mm jack. The Topping DX5 II rates higher with more rated balanced power for less.

#10 Topping DX3 Pro+: $199.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 117 dB, so its noise and distortion are inaudible. Topping rates it at 1,800 mW into 32 ohms, enough for most planar magnetic headphones, and it accepts USB, optical, coaxial and Bluetooth with SBC, AAC, aptX, aptX LL, aptX HD and LDAC, plus an RCA line output.
Cons: There is no balanced headphone output, only a 6.35 mm jack. The Topping DX5 II rates higher, measured cleaner and is rated at far more balanced power for a bit more.

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.

#12 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.

#13 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.

#15 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.

#16 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.

#17 Chord Hugo 2: $2,595.00 Headphones.com eBay
Pros: Audio Science Review measured 112 dB SINAD, clean for nearly all listening, and Chord rates it at 740 mW into 32 ohms, enough for most planar magnetic headphones. It is a battery powered portable unit with about 6 hours of play, Bluetooth with aptX, and optical, coaxial and USB inputs. RCA outputs let it double as a home DAC.
Cons: It costs far more than the SMSL DS20, which rates the same and measured higher SINAD. There is no balanced headphone output, the USB port is the older micro USB type, and battery life is short at about 6 hours.

#18 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.

#19 Schiit Magni Unity with Mesh DAC: $239.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 109 dB with the Mesh DAC fitted, clean enough that noise and distortion stay out of the way for nearly all listening. Schiit rates it at 2.5 W into 32 ohms and 415 mW into 300 ohms, enough for power hungry planar magnetic and high impedance headphones, and its RCA preamp outputs can also feed powered speakers.
Cons: There are no balanced outputs and the only digital input is USB-C, with no optical, coaxial or Bluetooth. The Topping DX3 Pro+ rates higher for less and adds those extra inputs.

#20 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.

#21 Chord Mojo 2: $566.86 Amazon eBay
Pros: Audio Science Review measured a SINAD of 110 dB, which is clean for nearly all listening. A rated 600 mW into 30 ohms is enough for most planar magnetic headphones, unusual muscle for something this portable. It takes USB-C, Micro-USB, optical and coaxial inputs, offers both 3.5 mm and 4.4 mm outputs, and includes built-in DSP tone control.
Cons: It costs far more than the TRN Black Pearl, which rates higher and measured cleaner at 117 dB. The Fosi Audio DS3 also matches its rating for much less. At 185 g it is much bigger and heavier than a typical dongle, so it is less convenient to carry with a phone.

#22 Khadas Tone2 Pro: $159.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 118 dB, so its noise and distortion are inaudible. 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.

#23 SMSL D12: $149.59 HiFiGo eBay
Pros: Audio Science Review measured 115 dB SINAD, which puts its noise and distortion at the point of being inaudible. SMSL rates it at 300 mW into 32 ohms, enough for most headphones, and it adds Bluetooth alongside USB C plus RCA outputs for powered speakers.
Cons: It has only a 6.35 mm output with no balanced jack and no optical or coaxial input. The Tanchjim Luna rates higher with similar SINAD for less, and 300 mW is not enough for demanding planar magnetic headphones.

#24 Fosi Audio SK02: $99.99 Amazon eBay
Pros: It is rated for 755 mW into 32 ohms from its 4.4 mm balanced output, enough for most planar magnetic headphones. 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.

#25 Gustard A20H: $752 HiFiGo eBay
Pros: A rated 2.4 W balanced into 32 ohms and 264 mW into 300 ohms is enough for planar magnetic and high impedance headphones alike. 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.

It is unusually flexible for the money, with USB, optical, coaxial and Bluetooth inputs (SBC, aptX HD, aptX LL), RCA line out, a 4.4 mm balanced headphone jack, a microphone input and bass and treble knobs.
Cons: Fosi Audio doesn’t publish a 32 ohm power figure, so its headroom for hard to drive headphones is unclear. The SMSL DS20 rates higher for a little less, and the Fosi Audio SK02 rates slightly higher for much less. Its Bluetooth lacks AAC and LDAC.

Pros: It is a portable DAC and headphone amp with a 6 hour battery, USB-C and 4.4 mm balanced analog inputs, and 6.35 mm and 4.4 mm balanced headphone outputs. Woo Audio rates it at 1,200 mW into 30 ohms balanced, enough for most planar magnetic headphones, and Audio Science Review measured a SINAD of 101 dB, clean for nearly all listening.
Cons: The Khadas Tone2 Pro rates higher and measured cleaner in Audio Science Review’s tests for a small fraction of the price. Battery life is short at 6 hours, and the 1,200 mW figure applies to the balanced output.

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.

#35 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.

#36 SMSL M10: $455.00 Amazon eBay
Pros: It has balanced 4-pin XLR headphone and XLR line outputs alongside a 6.35 mm jack, plus USB, optical and coaxial inputs. SMSL rates it at 340 mW balanced into 32 ohms, enough for most headphones.
Cons: Audio Science Review measured 95 dB SINAD, fine for most headphones but sensitive in-ear monitors may reveal hiss or noise. The Qudelix T71 rates higher with better measured SINAD for less, and there is no Bluetooth input.

#37 Essence HDACC II-4K: $649.00 Essence Electrostatic eBay
Pros: It accepts four HDMI inputs with pass-through plus USB, optical, coaxial and analog, making it a hub for TV and console audio. RCA and balanced XLR outputs, digital outputs and a remote controlled volume knob add flexibility.
Cons: Audio Science Review measured 99 dB SINAD, fine for most headphones but sensitive in-ear monitors may reveal hiss. Essence doesn’t publish a 32 ohm power figure, there is only a 6.35 mm headphone jack, and the Neutron HiFi DAC V1 rates higher for much less.

#38 Pro-Ject Pre Box S2 Digital: $399.00 Amazon eBay
Pros: It accepts USB, optical and coaxial inputs and also works as a preamp with a variable RCA output, all in a compact box about the size of a paperback. Audio Science Review measured a SINAD of 100 dB, which is fine for most headphones.
Cons: Pro-Ject rates it at only 68 mW into 32 ohms, which suits in-ear monitors and easy headphones but not demanding full-size models. At 100 dB SINAD, sensitive in-ears may reveal some hiss, it has no balanced outputs, and the Neutron HiFi DAC V1 rates higher and measured cleaner for less.

#39 NAD C 658: $2,299.00 Upscale Audio eBay
Pros: It is a full streaming preamp with Ethernet, Wi-Fi, Bluetooth with aptX HD, two optical and two coaxial inputs, analog RCA inputs and an MM phono stage. Dirac Live room correction, stereo subwoofer outputs and XLR preamp outputs make it a flexible hub for a speaker system.
Cons: Audio Science Review measured only 90 dB SINAD, so sensitive in-ear monitors may reveal hiss or noise. NAD doesn’t publish a 32 ohm power figure for the headphone jack, and the SMSL M10 rates higher for far less.

#40 Leckerton Audio UHA-6S.MKII: $239 Leckerton Audio eBay
Pros: It is a portable battery powered DAC and amp with micro USB, optical, coaxial and 3.5 mm analog inputs, lasting 10 hours from digital sources and 30 hours in analog mode. Audio Science Review measured a SINAD of 94 dB, fine for most headphones.
Cons: It is rated for only 55 mW into 32 ohms with its stock op amp, which suits in-ear monitors and easy headphones only, and sensitive in-ears may reveal hiss at 94 dB SINAD. It has no balanced output and still uses micro USB. The Pro-Ject Pre Box S2 Digital rates higher and measures cleaner, though it costs more.

#41 xDuoo DM-01: $279.00 Amazon eBay
Pros: It supports a long list of Bluetooth codecs, including LDAC, aptX Adaptive and LC3, alongside USB-C. A rated 1.5 W into 32 ohms is enough power on paper for most planar magnetic headphones.
Cons: Audio Science Review measured just 38 dB SINAD, a severe and audible level of noise and distortion. There is only a single unbalanced 6.35 mm output, and the Loxjie D30 rates far higher and measures transparent for much less.

#42 HiFime UDA38Pro: $249.00 HiFime eBay
Pros: It combines a DAC and headphone amp with USB and optical inputs and an RCA line output in a small 220 g box. HiFime rates it at 125 mW into 30 ohms with its external 9 V supply, which drives most headphones.
Cons: Audio Science Review measured a SINAD of only 70 dB, a real audible weakness that can show up as noise or distortion. Power drops to 70 mW on USB power alone, there is only a 3.5 mm output with no balanced option, and the Pro-Ject Pre Box S2 Digital rates higher and measured far cleaner.

#43 Ayre Codex: $1,950.00 Ayre eBay
Pros: It combines a DAC and headphone amp with USB and optical inputs, RCA and XLR line outputs, and a 6.35 mm jack plus a pair of 3.5 mm jacks usable as a balanced headphone output. The volume knob steps in precise 1 dB increments.
Cons: Audio Science Review measured a SINAD of only 68 dB, a level of noise and distortion that is a real audible weakness, especially with sensitive in-ear monitors. Ayre does not publish a power figure into 32 ohms, so its ability to drive demanding headphones is unknown. The Pro-Ject Pre Box S2 Digital rates higher and measures far cleaner for much less.
