This is especially true when the digital processing is complemented by a very pure and clean analog section. The full potential of this chip can only be realized when it is surrounded by the very best analog processing. For this reason, and the reasons stated in "Part 1 - Analog Processing" it is unlikely that any two different products with the ES will sound or measure exactly the same. Benchmark reserves the top 3.

It is on kind loan from a member. This is a hard product to find online. There are many variations there of the same theme. Due to inclusion of AC mains power supply and hefty chassis, there is a very solid feel to this otherwise budget product: As you see, there are no switches so just plug in the headphone cable and go.
The volume control has a stiff feel which is fine by itself but the knob is too slippery to be able to turn it easily. A textured one should have been used. The back panel is simplicity in itself: The RCA have fixed output. Naturally there is no regulatory certification so cross your fingers that the mains input is properly wired and grounded. But for fair comparison, I dialed it down 1 dB to get it closer to 2 volt and got this: That is very high level of distortion dominated by the third harmonic.
SINAD signal over noise and distortion as a result falls very close to the bottom of our list of all DACs ever tested sorry forgot to highlight it : I think it is tenth from the bottom out of the list of some DACs. Not good. Surprisingly, jitter performance was not too bad: That spray to the left is likely power supply related and at any rate, too low level to be of any audible concern. Here it is with ohm load: That is dismal amount of power for a mains operated unit.
My standard is milliwatts of power and we are way short of that at just 27 milliwatts. Channel balance was OK until you got close to minimum level: Output impedance was comfortably low: Headphone Listening Test I started testing with the Sennheiser HD headphones using my bass heavy track as I always do.
At first there was reasonable amount of power but the moment the bass notes arrived at somewhat elevated listening level, the sound broke up like I had not heard before. There was clearly, audible crackling and drop outs. The former was so bad that I feared for damage to my headphones.
Measurements predicted the shortfall of power as they typically do. Distortion is quite elevated from DAC itself. The headphone amplifier is decent if you keep the power low.
But exceed its limits at your own risk as the severe distortion could be damaging to the drivers. If there is none, and you can find this unit, I guess it would be an OK choice. But otherwise, I like to encourage you to buy something of quality. Fall planting season is upon us and I have decided to go "green" or should I say, pink. I am thinking of getting harnesses for the panthers and see if they can help plow the garden for us rather than using my tractor. Looking online, pink panther harnesses are not available so have to be custom made at high cost.
ES9018K2M XMOS DSD DXD 384kHz USB DAC with Bit-perfect volume control and SPDIF input
After many hours of work on customize the xmos firmware on this USB DSD DAC, audiophiles can move the volume control bar up and down freely in the computer volume mixer panel and still enjoy bit perfect audio. Please notes there are many so called bit-perfect device can play DSD but you must set the computer master volume control to full volume. No need to go to foobar preferences everytime to change the output device. The circuit is designed and printed on the PCB directly. The IIC volume control is only active when you are moving the volume bar to change the volume, it is totally stopped when not in use. No pop sound.
[AUDIO][PIE][V30/V30+] Restore Legacy Audio Configuration
Audio preamplifier and receiver? Professional audio recording systems and mixing consoles? Digital audio workstation 1. This is for oversample bypass mode only. The maximum sample rate using the internal oversampling filters is kHz. When Mute is reset the attenuation level will ramp back up to the previous level set by the volume control register.
