everything sounded great until the upgrade

Like most, holding a mental breath to see if one man decides to become the most hated fool on the planet over a desire to further waste lives and real estate.
Politics aside, there's a nastier end game awaiting if we don't start acting like one species v. tattered tribes tormenting each other...

You are very grounded on earth...

My deepest respect....

I would have said "that's dark" a few years ago but in the sci-fi we live in, reason can be a pleasant surprise :)

It could be that a new very good component now shows up how relatively poor the others are. This is common and if not careful leads you down the never ending audio rabbit hole. You buy better speakers, better speakers now need better amp, better amp now needs better DAC, better DAC now needs better source, all done, NIRVANA, no the old speakers are now the weakest link. You buy new speakers but ++++++++. Toe out of speakers means your ears and the extremely directional tweeters are not aligned, this can make speakers sound less bright.

except that I need to stick with my speakers and test other options, cables, DAC, smaller improvements. I received so many great suggestions, I am still playing with my system ,

Without knowing, it may in fact be that "X" sucks is your problem... impossible absent data.

But keeping it simple - you liked amp A, you dislike amp B.  What's the question?

Amp synergy is not usually a huge deal unless either the speakers or amp or both are way out on some extreme - which in most cases means flawed.

You will also hear "its break in".  Uh, not in extreme. As a professional designer do you know how many new and cold things i hear? Sure they sound better warm. But they don't sound bad cold....unless they are in fact bad.

Why did you buy something without hearing it first?  All the pointless bickering here aside, that's what matters - where the eardrums meet the air
