Thanks. I don’t consider myself a tube roller, but try different variants when the tubes need to be changed. It would be convenient for people like me if PS Audio would compile such a list. I suppose that’s not their responsibility, but just the same it would be a great benefit to their customers.
IMO there would be somewhat limited utility in such a list because there’s little universal agreement on what tubes are “successful” in the BHK pre and amps. I’ve used my BHK pre with four different amps and two different sets of speakers and multiple combinations of cables and vibration controlling footers. What sounds best in one application is “meh” in another. Add personal sonic preferences to the variables with equipment and it all just becomes quite confusing.
