To add some fuel to the fire here. I don't have the Magico speakers but I do own the Theta Prometheus class D monos and also have, First Watt J2 and F6 and Pass 30.8 also have the Decware Zen triode tube amp. I feed mine directly from a DCS Rossini DAC/clock. I've had many an amp and no way does the Class D get stomped all over as Audio Troy says. I agree that they might sound a touch drier than the others but still I am always a little surprised how good they do when I put them back in the system. I have been going back and forth with these amps for months also switching in and out some different speakers. For me it kind of depends on the music and the volume as to what I prefer. I understand the though behind not wanting space heaters in the room, that is what drew me to class D. If that is a high priority then Class D is pretty good. I had a Coda TS400 and a Krell Duo 300 and I'd take the Theta Class D over either of those amps on sonics alone. I have a friend who has some Bel Canto Ref 600 amps that sound very good and smooth at his system as well. If I was choosing amps on sound alone I probably wouldn't go class D but if heat and power consumption was in any way important I would choose them and never look back. They do sound good and as AudioTroy says you can flavor their sound with upstream gear.
Anyone here with Magico A3 driven by Bel Canto Ref600's?
Contemplating the A3's and would like to know if the REF600M will drive them properly. Currently using Martin Logan Montis and these aren't a great indication of what these amps can and will do.
