Voltage conversion in Wyred4 Sound DAC

If you email W4S chances are EJ will respond personally. Can't get any more direct than that

Also recommend contacting EJ at Wyred. Wyred has a much smoother sound than the Benchmark which can sound very bright.

According to Benchmark Technical Director John Siau Benchmark was designed purposely not to sound warm but neutral instead. Warm sound works wonderful with voices or guitar but not so great with instruments that have more complex harmonic structure like piano or percussion instruments. Overly warm gear can, according to John Siau, make piano sound like out of tune. Benchmark is very smooth and resolving. Because of that it can reveal deficiencies in the system. It revealed bright sounding aluminum dome tweeters in my previous speakers but sound wonderful with my current speakers that have well implemented soft dome tweeters.

So what's the difference? Bright tweeter and warm DAC or warm Tweeter and neutral or bright DAC?

To me the most important thing a DAC can do is bring layers and width to the music coupled with neutrality. W4S can do that

Benchmark DAC1 is not bright. It was used in many studios for its neutral performance. Covering bright system deficiencies with warm DAC is the worst thing you can do.
