@roxy1927 I would add Pass X260.8 into the mix. I had these amps driving my Wilson Sabrina and they’re outstanding. Plenty of Class A power as well. Good synergy with ARC Ref 6 that I had for few weeks on loan. Unless you really need the power of the X350.8, I’d opt for the mono blocks.
Haven’t heard Levinson in a long time and don’t know how it matches with the ARC preamp.
Coda is amazing as well but if you’re running balanced interconnects might not be a good match with ARC preamp due to Coda’s relatively low input impedance.
If you mention your speakers you might get better and more accurate recommendations.
