what amps to replace your heavy weight class AB amps would depend on whether you have enough fun chasing audiophile class amps yet. I have, and I bet
@AcuDefTechGuy has too, though he's still promoting ATI amps, but at least he wouldn't push the likes of Krell, Mc, and Passlabs, except may be Bryston's just for those who value extra long warranty and are willing to pay premium for it.
I prefer big BRANDS and I'm not gonna lie. LOL.
As long as I don't have to PAY TOO MUCH for them!
If I were a billionaire, you would see me own something like a $200K amp.
A huge factor in this hobby is "pride of ownership" or how it makes you feel.
To me it doesn't matter how much money I save if it doesn't give me that personal pride of ownership, which is 100% different for everyone.
To many Emotiva fans, owning Emotiva gives them plenty of pride of ownership. To me, I would not own an Emotiva amp. Everyone is different.
Same way with Monoprice or Outlaw, although some of their amps are made by ATI, which gives them a lot of brand power. But some people still see the "Monoprice" and "Outlaw" brand and it might not give them enough personal "pride".
Krell, Mark Levinson, Theta Digital (own by ATI),McIntosh, Bryston, Pass, Classe, etc., would give me huge pride of ownership, but they fall in the "PAY TOO MUCH" category.
ATI, Adcom, Rotel, Anthem, Parasound, Yamaha MX-A amps (not pro amps),Marantz would give me pride of ownership and fall in "affordable" category.
So pride of ownership might or might NOT be a significant factor for the OP.
