I have these speakers and have used McIntosh MC611, Naim NAP 300, and Chord Ultima 6. The Ultima 6 was far superior. McIntosh too bloated in the bass, Naim was good, but the Chord was mind blowing.
Solid State Power Amps
I’m currently using 2 PrimaLuna EVO 400 power amps. I want to try my EVO 400 preamp with solid state power amps. I am considering the BHK 300, MC830, Accuphase 250 or 300 and the Pass X260.8. My budget is around 25k. Any thoughts or suggestions would be appreciated. If there is something else please recommend it.
