Amplifier Power tubes - important to sound?

@emergingsoul Another excellent discussion. You folks know who you are. Thanks.

The most significant tube roll I evet did was to go from KT88’s to KT170’s. They do something magical to the bottom end and low mids. Their shape will not fit in all AMPs.

The chillaxed EL-34s don’t punch as hard but are like a first love, gone but not forgotten.

@immatthewj Apparently you're the only one not oblivious to the fact that OP started an identical thread to this back in February...and responses have been pretty much the same....maybe this is a test?

@wyoboy , I have come to the conclusion that OP's questions are not serious and that he is not interested in serious answers.  

@emergingsoul OK so you started this same discussion in February of this year--did you not like what you heard at that time?  Or did you forget?  Or were you just seeking confirmation of what was said back then?  And if the answer was different this time then what?

My thoughtful niece tells me that having Alzheimer’s can lead to a wonderful experience of being able to watch really great movies over and over again.

Of course when she drops me off in the middle of nowhere or in a shopping mall I wonder why.

Yes very important also important is coupling capacitor(s) for cleaner sound quality of the amp
