RE: No opamps

You mention that "... 'leanness' has to do with designs using copious amounts of corrective feedback which compromises a natural presentation of harmonics. Which is why I avoid op amp based designs..."

No opamps in the Freya S active stages. According to what Schiit had to say about their Nexus gain stage...

"What is this Nexus thing? More Schiit blathering?

Nexus is what we've been referring to as the "holy grail gain stage" internally, during development. Now, maybe we're a little too much into Monty Python, or maybe we're a bit touched in the head. But it took a long time to come up with Nexus, which is a current-feedback stage with nested differential amplification, and has the following interesting qualities:

It does not exhibit the N/N+1 gain relationship when fed a single-ended signal, so it seamlessly converts single-ended to balanced.
It also converts balanced to single-ended.
It also is quite happy to amplify, differentially, a differential signal for differential output.
It does this without summers, op-amps, or any other tricks; it is a single, discrete, differential stage"
