Got this recently and only tested couple pair of wormbox speakers and my opinion of pioneer vintage silver models are elite class amps! My friend was planing to throw this in junkyard, luckyly I make it save from that. Only minus is b pair speakers left side is dead and front panel have two corners crooked. Check3d inside there is there empty slot for fuse (dont' know how it said but from finnish-english direct translation:) power input circuit?, outside everthing else seems to be fine only little dust proplem😁

Came buy one of these at a recycling centre, works a treat and is a surprisingly well rounded amp in sound performance and power

The sound level makes it seem that 32 wpc is rather conservative in my view, more in the region of 50-60wpc. It is quite bass heavy with the loudness switched on which makes you feel that you are missing out on sound quality somewhere, turning down the bass level while the loudness switch is on helps and over comes this.

This amplifier is quite a battleship in terms of reliability, and seemless power, I have used this amplifier with misson 734i speaker s, and the sound is powerful with bass that bassheads would love, but also used this amplifier with a set of mission 732s and the sound results were rewarding, but being carefull not to damage them, as this amplifier will push speakers to there limit.
