This amplifier was professionally installed by Audio Design in San Jose and lightly used for approximately one year. The amplifier powered two Audison TH 1.5 Violino Tweeters and two 3.0 Voce Mids, and was controlled via the Audison bit One HD Virtuoso Processor. I listen to mostly Classical music and Jazz at soft volume. It is in excellent working condition and was updated last about six months ago. See my other listings for Audison TH speakers and other amplifiers.
