I feel that if a DAC needs "special" software to show its best, then inherently something is broken. You don't need special software to run any other DAC I know of because if you do, put it in the DAC to begin with.
Nah, but then you didn't get it quite. This DAC has been created deliberately 100% on purpose to contain exactly nothing just in order to allow "us" to provide it with the filtering which seems best to you and your ears. So, it's a NOS/Filterless DAC and it *needs* that filtering. Not everybody acquainted to NOS will tell you this, but I do. And as I said before, that XXHighEnd provides that best filtering (everybody is allowed to use the playback software of choice) I can't help. Sort of.
Can we say this is modern times ?
Regards and thanks for the welcome.
