The speakers are Martin Logan SL3's and 4ohm impedance. Martin logan's are noted to be power hungry and not real efficient.
Adcom 5802 Stereo amp
The manual states the heatsinks can get VERY warm under normal listening and this has been consistent in prior reviews. I just purchased this unit and so far it is only minmally warm.It stays on 24/7 since there is no standby switch. It operates in Class A at lower volumes then switches to A/B according to the manual. This unit pumps out 450 watts to a 4 ohm impedance. Anyone out there familiar with this amp?
