Exceptionally enjoyable amplifier! I have had two SU-V5's now, my father had a silver one that he got from a local 2nd hand shop in 1989 approx. for about 25 GBP, but he was a chain smoker and the selector switch and also volume control both started to go very bad since about 2008 onwards (probably gummed up with tar) so I had to get rid of it in 2013.
Since I prefer black audio components, I got myself the black one in very good / excellent condition from Ebay in 2013 for about 70 GBP. Again the selector switch and volume control on this one are just slightly sometimes a slight problem but only until I turn them slightly again, it's hugely more reliable than my father's.
The sound is excellent, the treble is very bright and clear without sibilance through the 1 dome tweeter of my MS Pageant Series 2 speakers, and there is plenty of really deep bass without distortion, enough to make the Pageant's LF drivers move in and out a huge amount when playing organ music with 32 foot pipes.
The speakers (50W/ch) seem to be the weak link not the amp. The noise floor is undetectable through speakers or headphones in a dead quiet room. I love the fluorescent peak power meter which still works perfectly, and it's dual readout range (x1, x100).
Now for why I love this amp. so much, it's for the incredibly MUSICAL sound. I compared it directly with my Sony STR-DA1200ES AV amp. just for kicks and the Sony is dead flat and cold and dull in comparison, so neutral and unmusical and lifeless and boring. The Technics is nothing like it, there's a night and day difference. The Technics definitely has a character to the sound, it makes anything sound lively, musical, warm and engaging and exciting.
Particularly effective with Stock, Aitken and Waterman pop music, heavy Classical Organ music, and big American Theatre organs music. This amp. has a big sound. This amp. and the MS PS2 speakers are a dream combination for me for now! Highly recommended. It's only real drawback is the lack of a remote control capability and well-known selector switch/volume control problem as they wear a little with age (I knocked off 1 point for these, maybe electrical cleaning spray might help on the bad ones?).

I acquired this amp in mint condition from a friend back in '95 for a 2-channel home theater setup. At 60 wpc and paired with sensitive Klipsch towers. Concert DVDs sounded tonally fantastic with reasonable dynamics despite a modest damping factor of 20 at 8 ohms and 40 at 4 ohms and equal power at both impedances dynamics are more than adequate sounding even authoritative.
S/N ratio of both line and phono is not fantastic on paper if you care to look at the manual but nothing can be heard with the faintest music playing. One of the fluoro VU meters peaks a little earlier than the other but my technician said both channels were running even and that the amp's fluoros were not the best and could not be replaced or repaired, so judging for ear has since been my motto.
The thing is built like a tank; at 7.8 kg is a big chunk of all-metal amp. Not a big fan of anything Technics except for thir CD players but this puppy proved me wrong bigtime and turned out to be a keeper.
The loudness button has a center freq. of 50 hz and provides a max. boost of 9 db, very useful for small speakers and even for enhancing the punch of big subs when it's lacking. The speaker selector is managed by an audible relay which does a great job of switching between 2 pairs of speakers at any volume without a single thumping noise that could damage them. The rec selector is the most intricate I've ever seen bar some Yamaha preamps.
Compared to my Pioneer SX-980, this is a mediocre amp but at face value and compared to most current budget amps this puppy has state-ofthe-art performance, esp in the tonal department.
If you come across one of these, keep in mind it's only mediocre for its time, but better than most of today's amps, and don't pay a fortune for it.
