Very well built with extremely detailed tidy construction.

Doesn't run hot at all and the rated power consumption of 640 watt is misleading. The unit has Technics class AA technology (biased class A/B), not actually class A and nowhere near as hot as a pure class A. That said the smoothness in the sound produced when matched well comes very close.

The amplifiers base sound signature is towards being bright and easily sounds harsh. I had to balance the system with Van Den Hul CS 122 speaker cables to mellow the treble out. This amplifier definitely delivers enough punch and control. Alternatively can use the tone controls to balance.


Furthermore by-passing the preamp circuit via the direct input mode gives a better detailed sound. The tone controls are very handy but do take away a bit from the clarity from the former.

Delicate construction - The amp under repair must have had a try before by someone else, with the poor result of the tiny volume PCB split by a heavy impact. Beyond, the general change of European net voltage from 220 to 230 V~ may be harmful to net transformers sparing the few windings required for apt compensation; as a 5 % voltage rise means a 25 % rise in power consumption, the SVI 3205 Hybrid amp of the SU-V660 may be ruined in no time.

NICE SOUND LOADS OF POWER AND GOOD FREQUENCY RESPONCE.
LACKS THE ABILITY TO EASILY CONNECT A GRAPHIC EQ.

Bought this amp in mint condition a few months ago for only $70.- (Australian) and it's one of the best purchases I've ever made. I have owned a lot of amps in the past, such as Marantz, Pioneer and Denon but never anything as sweet as the Technics SU-V660. Plenty of power to drive my JBL LX44 speakers and all my music on CD, MiniDisc and Vinyl now sound full and as it should.
My search is over and I can finally be at peace.. Amen!
