Counterpoint Hybrid Amps: How do they sound?


I've been curious about the Counterpoint SA-100 and NPS amps. They had a tube driver stage and MOSFET outputs. How do they sound compared to other things out there? Are they reliable? Counterpoint was famous for having equipment that was unstable and blew up. I had been told that the designer was not as technically adept an engineer, and that was why the circuit designs were not the most stable, and certain components were stressed in the circuit.

Anyway, the concept of hybrid amps has always been interesting, and very controversial. The different thoughts:

Hybrid amps have the best of tubes and solid state.

Hybrid amps have the worst of tubes and solid state combined.

Hybrid amps should use tube input stages and solid state output stages.

Hybrid amps should use solid state input stages and tube output stages.

I have owned a few Counterpoint products over the years and none were unreliable at all. Originally, I used them to feed Apogee speakers with Theta source material. I actually still have a couple stored (an SA100 and an SA220). Compared to SS of the time, I found them quite musical and reasonably priced. With good synergy, you could get pretty enjoyable sound.

I recently hooked each of my remaining two Counterpoint amps (in succession) up to a pair of Avalon Opus Speakers and a pair of Kharma Ceramique 2 speakers with Levinson digital source and was disappointed with the performance. Both were still musical, but compared to a number of amps I either own or have recently auditioned, there were a number of problems. My complaints were with what I must guess is an excessive "mosfet mist" - worse in the 220 than in the 100. The soundstage was wide and deep, but definition of individual instruments was not as precise as in many current amps, and air around voices and instruments was lacking.

The hybrid approach can be found in a number of current production amps - some wonderful (Lamm), some disappointing IMHO (AR), and others I have heard great things about but haven't auditioned (Llano).

If you have tough to drive speakers but love tubes, a hybrid may be a good choice - or a tube pre with a ss amp. I am considering the latter now or a really big tube amp.

Hope that helps...
