Spent some time with my wife this afternoon deciding which of 2 amps to keep. System as of now & for the forseeable future is "sources; Optonica RP 3636 TT, Oppo OPD971H CD player & a nondecript Sanyo cassette deck" into a CT 7 preamp, a M-4.0t amp driving a pair of Vandersteen 2ce's. Really impressed by the clarity & detail of the M 4.0t as well as the tight bottom end. Looking forward to many more hours of listening.
