The G-7700 (120 watts/channel) is a phenominal audio product. Tuner is excellent but its the amp section that blows EVERYTHING away. I have bought and sold a lot of audio equipment (tube and SS), but this unit "spanks them all". I have owned 9090's, G-6000, G-6700, and G-9700. Sonically the G-7700 is KING. Lets look at some of the other receivers that I am compairing it to: Kenwood KR-8010, Pioneer SX-950, Marantz 2285b, and the G-9700(200w/ch.). Sansui across the board will sound better; but the G-7700, if it is set to factory specs., will dust anything in its catagory.
My dad bought the g-7700 in 1982!! I still have it running with the original sub woofers just changed the tweeters and mids The g-7700 has so much power that i never cranked the volume pass the half way mark! For a 30 year old receiver, it sounds just as good as when my dad first got it. He gave it to me in 2000 and I've had my fair share of noise complaints. I was thinking of getting a new receiver buy why? It sounds so good! I think that it sounds better than the receivers of today!!!
