Cause of different sound between dacs

Two DACs can sound identical just because you are using a poor quality preamp or any active preamp at all in the system. These can totally homogenize all sources.

I don't use any preamp, active or passive. Makes a world of difference.

If you must use one, use a passive transformer. Requires the DAC to have decent output drive though...

Power supply is a huge factor. Also the output caps used are very, very important.

Great active tube preamp is the best option IMHO with any DAC.

Listen to them both and pick the one that sounds the best.

That's too simple.

I know, but it works.
