But who says an A2-capable amp should actually be driven into A2 in use? I thought you planned to operate the amp well within its limits, to get the DHT benefits without subjecting the amp to the sorts of stress that always spoils these little things?
I don't know how clean your 1-stage amp is in use, or what it gives you for tone, but the gold standard for me has been an un-stressed 45 X 6SN7; clarity and tone, too (but very limited power, obviously). I like the 2A3, too, but I only wound up with it to get more power, because the 45 was simply not practical FR (and neither was the 2A3, for that matter). But then, I was not driving 109 dB speakers (and, like you say, you're not using it FR).
I forget, so please remind me again of the actual net sonic benefits from DC coupling a DHT/SET amp. And does that ask anything different from your PS?
What did splitting the curve between the tubes, etc., wind up doing wrong?
Do you just hate the RC follower?
