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 #3 of 43 in DAC and Headphone Amp Combos - 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.

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 #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 #23 of 43 in DAC and Headphone Amp Combos - 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.

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.

Headphone Amplifiers
Ranked #6 of 19 in Headphone Amplifiers - SMSL VMV P2: $999.00 Linsoul eBay
Pros: Audio Science Review measured 116 dB SINAD, so its noise and distortion are inaudible. A rated 6 W balanced into 32 ohms and 700 mW into 300 ohms is enough for nearly any headphone, including demanding planar magnetic and high impedance models. It offers 6.35 mm, 4.4 mm balanced and 4 pin XLR headphone outputs plus RCA and XLR inputs and outputs, so it can also work as a preamp.
Cons: It has only analog inputs, so you need a separate DAC to play music from a computer or phone. The Topping A50 III earns the same rating and measured cleaner for a fraction of the price, and the Topping A70 Pro publishes about twice the power for less. At 3.25 kg it is a large desktop unit.

DACs
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 #4 of 30 in DACs - SMSL RAW Pro-DAC1: $699.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 123 dB, among the cleanest results available, so its noise and distortion are inaudible. It connects to powered speakers or an amp through RCA and balanced XLR outputs. Inputs are unusually complete, including USB-B, USB-C, optical, coaxial, AES/EBU, I2S and Bluetooth with LDAC, aptX HD and AAC.
Cons: The SMSL D-6S rates the same for a fraction of the price, and the Topping D70 Pro SABRE matches its 123 dB SINAD for less. The packet lists no volume control. At 1,900 g it is a large box.

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 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.

Ranked #10 of 30 in DACs - SMSL D400 Pro: $728.20 HiFiGo eBay
Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are inaudible. It has a wide range of inputs, including USB, optical, coaxial, I2S, AES and Bluetooth with LDAC, aptX HD, aptX, AAC and SBC, and outputs to amps or powered speakers over RCA or balanced XLR.
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.

Ranked #11 of 30 in DACs - SMSL DO200 Pro: $399.00 HiFiGo eBay
Pros: Audio Science Review measured 122 dB SINAD, so its noise and distortion are inaudible. Inputs include USB-C, HDMI ARC, optical, coaxial and Bluetooth with LDAC, aptX HD, aptX, AAC and SBC, which makes it easy to connect to a TV as well as a computer. It feeds amps or powered speakers through RCA or balanced XLR, with remote volume in variable mode, and costs less than the SMSL VMV D1se2 at the same rating.
Cons: It is a DAC only, so you need a separate headphone amp or powered speakers. The SMSL D-6S earns the same rating for even less if you do not need HDMI ARC. There is no I2S or AES input.

Ranked #12 of 30 in DACs - SMSL DO200 MKII: $398.65 Amazon eBay
Pros: Audio Science Review measured a SINAD of 121 dB, so its noise and distortion are inaudible. It accepts USB, optical, coaxial, AES/EBU, I2S and Bluetooth with LDAC, aptX HD and AAC, and feeds an amp or powered speakers over RCA or balanced XLR. It matches the rating of the Gustard X18 for much less.
Cons: The SMSL D-6S matches its rating for about half the price, so the extra money mostly buys more inputs. It has no headphone output, and at 1.2 kg in a wide chassis it needs real shelf space.

It accepts USB, optical, coaxial, I2S and Bluetooth with UAT, LDAC, aptX HD, aptX, AAC and SBC, and drives amps or powered speakers through RCA or balanced XLR outputs. A volume knob and remote with fixed or variable output let it work as a preamp for active speakers.
Cons: It is a DAC only, so you need a separate headphone amp or powered speakers. Several rivals with the same rating measured slightly cleaner for less, including the Topping D70 Pro SABRE and the SMSL RAW Pro-DAC1.

Pros: Audio Science Review measured 123 dB SINAD, so its noise and distortion are transparent. It sends RCA and XLR outputs to an amp or powered speakers, and accepts AES/EBU, optical and coaxial digital sources. It matches the rating of the Topping Centaurus and measures cleaner for a small fraction of the price.
Cons: There is no USB input listed, so a computer needs a separate USB to digital converter. It has no Bluetooth or volume control, and the SMSL D-6S rates higher with USB and LDAC Bluetooth for more money.

Ranked #22 of 30 in DACs - SMSL PS200 PRO: $87.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 120 dB, so its noise and distortion are inaudible. It is a small, inexpensive box with USB, optical and coaxial inputs and an RCA output for an amp or powered speakers. It measured cleaner than the SMSL SU-1 for about the same price.
Cons: There is no balanced XLR output and no Bluetooth input. The SMSL SU-2 rates higher and measured even cleaner at 123 dB for only a little more.

Ranked #23 of 30 in DACs - SMSL SU-1: $84.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. It is a compact, inexpensive DAC with USB, optical and coaxial inputs that connects to an amp or powered speakers.
Cons: It has no volume control of its own, so level must be set on the computer or the downstream amp, and there is no balanced output or Bluetooth. The SMSL PS200 PRO measured cleaner at 120 dB for about the same price, and the SMSL SU-2 rates higher for only a little more.

Ranked #28 of 30 in DACs - SMSL VMV D3: $3,499.99 Amazon eBay
Pros: It has a wide input selection, with USB, optical, coaxial, AES/EBU and I2S, plus RCA and XLR outputs for an amp or powered speakers. It is built around four PCM1704U-J chips in a large 3,960 g chassis.
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.
