+1 @three easy. I've had this conversation with Keith and never thought about rolling again. The tubes he chooses are carefully selected, just like the other critical parts in his designs. They may not have the kind of name recognition or "bling" factor others possess, but they WORK as intended in his designs and they continue WORKING for years and years without hiccups. So roll away with that in mind or maybe find something else to tweak and scratch that itch.
Herron VTPH-2A vs Rogers PA-2 Phono Preamplifier
I know there are plenty of Herron VTPH-2A fans on this forum, and I also know that Herron has discontinued this model. Rogers reportedly benefits from tube rolling while the Herron is problematic to roll for better sound.
Sonically, how does the Herron compare to the Rogers?
