A cheap and cheerful amp that's actually far better than you'd think on paper. The dated graphic equalisor is completely flat when centred and the electronic fet channel switching chip is bombproof, far more reliable than electro mechanical switches better units of the era used. both A-B testing this amp with better quality amps, and signal testing on a bench it holds up well, except a slight attenuation at the very lowest frequencies (if you use a separate sub this won't matter). The only problems seem to be the speaker selections switches. If they play up replace them, or bridge them out completely. If you can get one of these cheap, then its worth considering, especially as amp for a second system.



re: SX-2300

Yes the speaker selection switches acted up on my unit, but I opened it up and sprayed the switches with tuner cleaner and they work fine now. You only need to take off the metal lid. Only 4 screws as I recall. The switches had openings so the cleaner was easy to spray in. I didn’t use a lot.
