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.

Some of you hit the nail on the head -- 10 year old equipment has parts that are not of the resolution and finess of present day stuff. And, of course, there is the other problem of aging capacitors that have a life expectancy of 15 years (although many swear their 70's receivers are still kicking).

I'm sure the upgrades make the stuff sound pretty good; however, I think upgrades, esp. from altavista, are highly overpriced, and you lose most of your money when you sell. As opposed to buying something current, at a good price, you will probably lose very little when you sell.

There seems to be no agreement on reliability. Trejla & Ultrakaz say the preamps were the problem, Alruhl says he & his friend had no problems, but Justlisten had amps blowing right and left.

If, as Trejla believes, the amps are somewhat "dated" sounding, with some zing and electronic-sounding, I don't know if a stock unit is a good buy. I'm actually looking for a moderate size amp for a second system, and to use in my main system when I'm between amps, or maybe just to save on my Audio Research & Cary tube life.
