Incredible hybrid amps with 40 pound power transformers can drive any load. I used a pair on the amp eating Apogee Scintillas. 2 of the amps are freshly serviced by Stereo Exchange in Chicago. This amp was a Stereophile Class A amplifier. The are great sonically and sold for just under $6000 in the mid 90's. One can only imagine what these amps would sell for today. Bob
