I didn't mean that tubers were trying to fix or flatten tube sounds by changing cables etc... all I meant was that tubes tend to accentuate these changes whilst SS gear often makes these kind of changes almost inaudible.>>>>
Therefore people with tubes tend to have a different view of cables and interconnects than people who use SS amps.
I spent a lot more time and money changing out ics and speaker cables with SS equipment. Never satisfied with the sound I was hearing. Since I moved to tubes, preamp and power amp, I don't even think about changing cables. As for rolling tubes to change the sound, yes, I have in the preamp, (Sonic Frontiers Line One). Not because I did not like what I was hearing, but more of what I might hear from my system with other tubes.
