So as tomb has said, my new version prototype is working. And as tomb has said, I do think it sounds excellent. I am running the new version with a very nice pair of RCAs versus a 3.5mm mini to RCA cable with the old version, so it isn't a total apples to apples comparison. That being said, I do think, as a *system* including the cables, it sounds better than the first version.
However, I am trying to track down an offset problem with my build. It appears to be something specific with the op-amp as I've replaced many of the parts around it While the offset is higher than I would like on one channel, it is still in spec for what the maximum allowed for the chip. I'd ordered new chips late last week, that I should be able to get on Thursday. I've also ordered an alternative part that has better offset specs, at the trade-off of a bit less output drive.
So a little more patience and I think we'll be able to release the prototype board to you all very soon.
