[QUOTE="Ampdog, post: 696749, member: 144"] On the other hand, MadHat ...... I am going to try to state this cautiously. Amplifier designs should be such that there will be no difference using valves within an acceptable spread - certainly no audible differences. When designing (in the past) instrumentation amplifiers the demands were quite more stringent. But users could mostly not be expected to test replacements first. Still we managed (auto balance, negative feedback and such, not going to expand now). That is why I am, respectfully, mostly sceptical when large audible differences in 'sound-of-valves' are claimed. (Strange how mysteriously, particularly these days such are claimed. Decades ago when principles of amplifier operation were more generally known, such claims were less frequent ..... [/QUOTE]
