I've been away from building DAc's for a while but noticed this new analog stage at Twisted pair audio. I'm enthused to see a new discrete analog stage as there are so few available: Borbely (which needs to use old R2R DAC chips), Pass (same issue), and the zapfilter (compromised universal design.) My experience is that a discrete analog stage can have a very positive impact to sound quality.
The issue I see with this Counterpoint is the fact that you need a balanced to SE converter. Now unless I missed something, all the balanced to SE designs are opamp based which would negates the purpose of building a discrete analog stage. I remember Pass had a discrete line stage that could be used to convert balanced to SE but I'm not sure this has the SNR (hum) reduction you are supposed to get when you tie a balanced signal into SE. I hate the sound of audio transformers so thats out of the question (they are never transperent.)
So I am curious to know if Counterpoint builders are all using balanced amps or if there is a smart solution for those of us with SE amps?
