Hello fellas hope everyone is doing good. I have the Lexicon MC-12 v5.25. It's amazing with my setup. Is classe better in terms of 2 channel or I should stick to my Lex. I listen to music 80% and Movies 20%.
My setup
Samsung 4k tv 55"
Samsung 4k Bluray player BDj7500
Mac Mini server Kodi
Lexicon MC-12
Carver Mt1.5 350 watts
Emotiva UPA 500 80 watts
Polk Rti12 fronts
Polk rti6 Center
Polkl rti6 Rear
SVS Ultra 13 Ported (monster)
Living Room 16ft X 12ft carpet
Here's my honest opinion:
a) If you like HDR/4K - get a modern mid to high range avr from Yamaha, Denon or Marantz
b)If you value music much more than 4k (or don't mind running audio-out from tv to processor) then upgrading speakers should be in your future and you could do much better than Polk RTI speakers.
Spending money for any electronics in your case will absolutely not bring any improvements, especially not for 2 channel listening.
