Ditto Greenman. Although I am a fan of Rogue, other than the ability to take control of a woofer's voice coil, the sonics of AtmaSphere amplifiers are several steps up from Rogue.
Rogue M-120 to Atma-sphere MA-1 Mk.II.2?
I currently use the Rogue monoblocks to drive Von Schweikert VR-5 HSE's and love the Rogues. But I've been reading all the praises of the OTL designs of Ralph Karsten. Anybody out there have experience with these two fine amps and could advise me if you got substantially more quality for the buck when trading up to the MA-1's? I'm also not sure of the compatibility of the OTL design with the VR-5's since they have variable impedance. Thanks!
