Thank you for your informative synopsis and for the memories. The Pioneer SX-1980 reminded me (especially your comments about 4 ohm loads) to some degree about a mid 1970s Sansui intergrated amp I owned. It was Sansui's largest and meanest, putting out 180 watts. And it looked like it could go toe to toe with any speaker and win with a knock out if called upon. But it quickly met its match with my first highend speaker called the Ohm F. I didn't realize it at the time but the F, which demanded a high current amp (hey, the Sansui "looked" the part), ate the Sansui for lunch. The Sansui could do nothing with the F but make it sound bad. I subsequently learned that the F had impedances that dipped close to 3 ohms (4 ohms nomimally) and that the Sansui put out *less* watts at 4 ohms than it did at 8 ohms and that it was current limited to boot. It probably ran out of gas at an accelerated rate as the load fell below 4 ohms.

Any way, I called Ohm and asked them for their recommendations. They gave me three, a GAS Ampzilla (the largest one?), the SAE 2500, which put out close to 500 watts into 4 ohms, and one other amp that escapes me (definitely they said to avoid tubes because of insufficient damping factor). I settled on the SAE which turned out to be a great match for the F.
