Have aerius (not i) and got an OdysseyAudio Stratos a few years ago (150wpc, red board with extra caps, total 180microF, to handle 1ohm loads). Great punch, instruments are texturally there in 3D, my wife and I are still constantly amazed every time we sit down in front of them. Paid about $1350 or so. (Klaus is great, too.) We regularly attend Library of Congress string quartet concerts and sit in the first few rows right in front, and decent recordings are almost as good as being there with this setup (also blackgated a used Superphon Revelation II preamp, pianos are amazing).
AMP Upgrade for Martin Logan Aerius i setup
I remain pleased with my M-Ls (w/ small Hsu Sub), I have a smallish (12 x 14) dedicated 2 channel music room, split time evenly between Jazz/Classical/Ambient with a bit of R&R now and then. CDs/SACDs feed through a Sony SA9000ES, vinyl via VPI Aries/Dynavector setup. Current power is Jolida 1501RC modded to level II (Underwood). Overall I have been pleased with the Jolida, but with the recent Table and SACD upgrades, I am wondering what a $2K solution might bring to the party. I like the simplicity of Integrateds, and have been reading up on Bel Canto, Krell, etc. Any and all opinions welcome. Am I spending enough for a significant upgrade??
