Voltage conversion in Wyred4 Sound DAC

Please also suggest some more dacs under $2000 with external switch for voltage conversion.
thanks.

Gnanasekhar, electronics equipped with switching power supply will often operate over whole voltage range. One example might be Benchmark DAC2 that operates 88-264V 50/60Hz.

I have older version - DAC1 but it is not universal (linear power supply).

Dac 1 and 2 both have a linear power supply.

Not only that Benchmark DAC2 has switching power supply but also
has many of them inside. It uses main +12V switcher and then
DC/DC converters to create +/-18V. I don't know of linear power
supply that can operate from 88 to 264 VAC without any switch and
at the same time to be able to operate up to 373VDC.

Look at the picture - perforated metal box in front is Switch Mode

I had asked W4S along time ago for the DAC2 which i bought.
The DAC-2 requires a power supply pin configuration change. Contact W4S directly. I was told that they can supply a power jumper that can be used to reconfigure it for one of the voltages, and be left out for the other. I have not done this but best bet is to double check with them. At least those designs were changeable if you open the cover and get the new jumper.

Thanks a lot for your kind opinions

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.

Hi Gnanasekhar,

I have been researching DACs with Dual power capability for a while.

Here are some candidates I found.

Chord Qute HD
Wavelength DACs (any model, I own the cosecant, that you can find used for around 2000$)
Auralic Vega ($3500) can be switched easily according to distributor.

There are others but they are more expensive.

AMR DP777 comes to mind

Hope that helps

" Covering bright system deficiencies with warm DAC is the worst thing you can do"

I think it's the second worst thing- buying gear and thereby assembling a bright system is the worst- but I've heard it so many times followed by the line "listen to that detail!"
