As Ultrakaz stated....I had a SA3000 pre-amp. PIECE OF JUNK. It picked up RF interference in the photo section in the form of an AM Religious radio station. I contacted Counterpoint tech support and was told to move because their POS pre-amp was not compatible with my residence. LOL. Eventually resolved the issue with ferrite beads.

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.
