The only change that I need to make would be the power amps, a pair of Lamms would be the best, (There's a lot of expensive junk out there that I've tried to listen to) & these do not run cheap, but I could dream about them. The Lamm Ll preamp. makes my whole system sing beautiful music and not just frequencies. Guided by my dear friend David Karmeli at "Damoka Intl." Thanks "my cumpa" for the tunes, now I listen to the music, and not the system. M.
