@douglas_schroeder There is a night and day difference between sound quality of a cool amp vs a warmed up amp (90 mins+). This is especially true in Tube amplifiers and class A amplifiers.
Anyone who disagree with this, I can’t take them seriously because I know for a fact their ears are unreliable. To even suggest the warmed up sound is identical to a cool one is WILD.
Erin the Youtuber, and the guy from ASR that do a lot of reviews, he has publicly admitted many times all amplifiers sound the same to him. Is he right? Absolutely not. Borderline crazy actually. BUT, what I really respect is that he says they all sound identical to him, not that all of them are identical.
Anyone that says warmed up time is BS, I know best to not take anything else they say seriously. If a reviewer can't see farther than 20 ft, why should I listen to what he says about what's 25ft away.
