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
Power Supply.

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.
