My first great power amp was a Marantz 510 with the matching 3600 preamp - bought them in 1978.

Last year, I picked up a perfect Marantz 250 amp ... 125 WPC into 8 ohms and 200 into 4 ... bench tested this amp at 166 WPC into 8 / 252 into 4.

It will definitely get a shot at the M100's and Martin Logans.
