Does it have an ASRC? Are you happy with it's performance? Do you not know the in & outs of your measuring equipment?Unfamiliar with it.
He's fairly uncompromising & categorical in his condemnation of the analogue output stage!I'll probably change over the analog output to the passive circuit published by Jan Didden as soon as I have a few weeks at home. With well-established levels, restricted bandwidth, and a healthy voltage level, I seriously doubt that the output section is the limiting factor; that's why 3/4 of Gary's page concentrates (rightly, IMO) on the input section where this is not the case.
Ok so you have issues with SPDIF input into the DCX - the attenuators will reduce the SPDIF level so might this be a problem for the DCX? for listening? Can I ask, if it doesn't sound right how can it be used to measure other devices?edit: If you're talking about the DCX input receiver (not the case for my other DAC), I have had problems at spdif levels, but far fewer with higher voltages. It's never done the "dull sound" thing, and I've only had it go frying eggs once. The high output of the Hiface is an advantage here.
So your M-audio 24/192 is impeccable?
