I don't own Cremonas nor Auditors, but I have good friends who do on my recommendation. Both use the McIntosh MA6900 integrated amp. Cremonas are 4 ohm speakers and don't put most SS amps in their best sounding load. The Mac autoformer amps sound sensational on these speakers, plus the speaker needs more power to sound good than it's 90db/w/m efficiency rating might otherwise indicate. When I considered building 2 systems around both speakers, I was consistently pleased with the synergy between all the Mac autoformer amps and the big and small Cremonas. If you can hear Cremonas and Mac amps together at one dealership, treat yourself to a few moments of amazement and ask to hear the Cremonas wired up to a pair of MC1201s. $16,000 or amps on $8000 of speakers makes perfect sense when you hear that.
