Hennfarm,I am very sorry, when I posted that, that was the furthest thing from my mind. I did not seek to make a bad impression. 'Au contraire. So sorry.
I am pointing out something that was wrong 83 % in my build, so far, and I was showing others how to improve their own audio gear.
Also, this is something I never personally have seen addressed in a comprehensive manner.
The intent was to allow others, if so inclined, and encourage them to optimize their own systems
Designing BY EAR is a great way to go about things, assuming you have high efficiency speakers, which makes it easy to hear these things.

Jeff, I know that is most likely your intention. Communication would be clearer if you refrained from using inflammatory language: "...have NO CLUE as to if ALL their expensive, fancy smancy film caps"
I got from your post that were excited and that you heard a difference in cap orientation when using a decent, in situ test rig... and that the resulting changes have made for an amp more to your personal liking.
Cheers,

Thank you, you got it !! No ones ever done a whole amp, to my knowledge, and posted about it on this Forum, for others to learn from.
I can't wait to do ( and hear ) the front-end B+ supply and driver stage Rk bypass caps next, C3 left, C3 right, driver Rks, left and right.
It is possible that " what I was missing " ( with non-optimal film cap orientation ) I was trying to make-up-for to my ears with wild amounts of bypassing, multiple bypassing. That " wild bypassing " of mine, may have been an error.
It will be instructive to me to hear the whole amp, film caps orientated, with all the wild bypassing gone, and then see if I only need conservative bypassing. Won't know till I orientate-optimize this amp's remaining front-end caps.
Also, I have been using a cheapo VISHAY 4 uF DC LINK cap for my driver stages' " Final Filter main cap ", and I know from my prior crossover experiments how much better a Dynami 4.0 E cap will be. So, I am also excited to eventually hear the Dynami 4.0 E feeding my driver stage's plate resistors. Me thinks that cap is mandatory for the performance I seek. Such a shame, the Dynami Cap 4.0 E went from $32 to $66 recently, but I'm told by Dennis Fraker ( Serious Stereo ) it may be worth $200+, relative to other 4.0 uF caps.
YES, I wanna HEAR all of this. Need to have a killer amp for my retirement years. This VOTT - as optimized, will likely be my last set of speakers, just need a really good amp, the weak link.
