RE: How many opamps are in your signal path?

John, mostly I was just responding to a humorous question. At least I hope it was intended to be humorous. I don't even KNOW (or care) how many I have, one for sure in the preamp there may be some in the DAC.

I've got quite a few of the Sheffield labs records and they surely do sound good. But I reckon there are plenty of factors involved in that besides op-amps. And as you well know back in the day op-amps were made out of tubes and then transistors, and then integrated ones which have varied all over the map in technology, implementation and performance over the last half-century. Stir in the knowledge, skills and bend of the designer and the question is beyond meaningless, it's misleading. Perhaps it's corollary is to ask how many parts are on the BOM?

Regards, Rick
