The mids and tweeters went a long time ago by being driven with an underpowered amp for many years, but the woofers survived. In my office I have realistic Minimus 7s powered by another M-400 cube. I also have a 5.1 setup of M&K speakers that are scattered in use around the house (from their previous incarnation, including am MX-125 Mk.II sub). My main sub is a Sunfire True Subwoofer Mk.II.
How do you like the Carver Amazing Loudspeaker IIIs? I know Carver built them to use amps of fairly good power. I have Infinity Kappa 9s for front, Kappa 6s for surround, 9.1 system with two Velodyne UDL 18" subwoofers at present. I like the ribbon tweeters of the Kappas. I did change the upper midrange 3" domes for the Dynaudio 3" domes on the front two Kappa 9s. When I go to specialty audio stores to audition speakers, I can't say I have listened to any except the Genesis speakers that I can say compare or exceed the sound of the Kappa 9s, especially the high sounds.
The Kappa 9s are known for demanding power due to their inefficiency (which helps the smoothness of the response). I am using two Sunfire amps, the Signature seven channel and a Signature two channel (for biamping the front speakers). I found that the improvement of sound from biamping is approximately equivalent to a substantial upgrade in speakers. Bob Carver, an old friend, said he likes the design philosophy of Arnie Nudel on the Kappas and assured me that the Sunfire amps could handle the Kappa 9 impedance, which can dip below 2 ohms due to the crossovers (Arnie gives actual listening primacy over worrying about impedance issues), and they have done so for a couple of years without complaint, running cool. The power of the Sunfire amps and biamping results in a richness, depth, and openness of sound that I have yet to hear when actually auditioning speakers in showrooms today.
