Is my new amp TOO GOOD?

@mojo771  I don't have your gear nor have I listened to it, but after you try some of the other suggestions e.g. break-in time, speaker placement you still find the top end to fatiguing  maybe swap the 12ax7s for lower gain 5751s.  

90 db is too loud, you WILL regret it later.

I suspect something was not quite right before, and now you are hearing things that were always there in the content, but not in the playback.

@audphile1 "...What jumped out as a red flag for me is the speaker positioning. 
11 feet apart is a bit much."

I definitely agree, good point!

I had missed the 90db comment. There is something very wrong if you feel the need to listen at 90db. I haven't done that since the terrible electronics of the 70's. I suspect this is an attempt to make up of other deficiencies. 

Also... do you really mean "toe out"? Typically speakers are toe in or straight out... I don't think I have ever seen speakers that were dialed in toe out. 

I recommend taking some photos of your system and creating a virtual system under your user ID. It is easy to do. It is sounding like there are lots of improvements possible. It really helps when we can see what is going on. 

Man you guys are hammering on the 90dB thing...
I mean it’s a fair point, protect your hearing - but the people I know with significant hearing problems didn’t get it from listening to a hifi at 90dB. It was far more egregious mistakes, like regularly firing guns without protection, or being in a band, etc. 

Obviously don’t listen at those levels for long sessions, take breaks, stop at any sign of fatigue etc. But also - live a little lol. I honestly wouldn’t care about hifi at all, if always listening at 70dB or below. The systems that "sound great at low volumes" are just gaming the Fletcher-Munsen curves in one way or another. 

That said, there is probably a correlation between the gear / systems liked and disliked within the "loud crowd", versus the "keep it down" crew.
