You had my interest with your several wee boxes.
Then I saw your ST70 and then you lost me completely.
Bought one of those New in '70?
Modded the hell out of it.. repeatedly (expensively too!) Over the decades.
Finally a simple stoopid NAD 3020 made the Modded ST70 sound like a Kids Transistor radio. I wasn't pleased.
Despite ALL the hype and Love lavished on the venerable ST70
It simply is NOT a very good design /amp.. period.
Took me 30 years to finally realise it, so you are not alone.
I can believe you. As I said, no match compared to SET (I have 45, 2A3, and 300B amps). With the combo I posted, I am just amazed how good the ST70 amp I have sound with the 01A preamp.
I agree the ST-70 is not the best, about the only thing that is really pretty good is the output transformers. I rebuilt my brother's ST-70 using the K&K mod (transformer phase splitter, 6n23p-ev differential driver stage, and differential power stage using NOS 6s3p-e tubes), shunt regulated power supply, and beefed up power transformer, run in triode mode, no negative feedback. Not much ST-70 about it anymore other than the chassis and output transformers. Sounded PDG.
Joe Curcio was as far as I.. OR my wallet would extend.
Throwing $$ at it only lightened my wallet.. when all was said and done.
Unfortunate, but true for me.
Can you "current owners' not accept that the Venerable ST70 was simply a mediocre amp design / execution ??
Dynaco was ALL about value (ie cheap as possible to build products)
Lots of dpcumentations on that.
I suppose if one replaced absolutely everything except the tin work ..
It might be genuinely bettered.
Would not be an ST70 though.
