This little cube is very good in it's (fairly low) class. Typical late 70's Philips pleasant sound, very good FM reception, good sound quality from both Tape and Phono inputs. Even with the built-in speaker it sounds OK, with quality speakers it shines. I used it with 4 ohm speakers without any problems (Bonsai Akustik Ideal, Quadral Rondo).

My only complaint is the loudness circuit that has no off switch, it is always on at low levels (20k out of 100k volume pot) and it boosts bass by 8 dB, which is way too much when using decent speakers. But you can compensate for that with bass pot, so it's not a big issue.

I would still prefer an off switch for loudness, and maybe one more line level input.

Dial lamps are a bit strange, three small 28V lamps wired in parallel. I used three 12V lamps in series instead.

Very nice for a small office/bedroom system, lacks power for large rooms. Certainly not an audiophile unit, but it doesn't pretend to be.
