Can fully appreciate that. I have long enjoyed CJ preamps with Gryphon amps...and still do. And then ultimately discovered the Robert Koda K15EX preamp which is sensational to take over for the CJ preamp in interacting with the Gryphon amps.
Eventually, I found myself gravitating towards trying the matching (also pure Class A) Robert Koda mono amps. And there is something cohesive about the sound where you can see how a designer has clearly designed them 'as one'. It does not by any stretch invalidate the Robert Koda-Gryphon combination. Who knows, some might even prefer it.
But I can see 'more' of what Robert Koch is doing in his designs when I hear the combination, and certain attributes of the Robert Koda preamp appear to come forth more intelligibly when paired with its matching amps.
I imagine that is more of what you are hearing as the CH 10-series digital settles into your CH 10-series amplification. Not just of a whole, but where certain elements of the CH sound appear more apparent, delivered more cleanly because the whole system is designed by one mind, one ear.
