Cool thread , the Old Japanese amps rock . I have receivers, as I enjoy the aesthetics more . I have a Sansui 9090, Sansui 7070, Marantz 2223B. The lower powered Marantz pairs very well with my Zu Omens and Klipsch KG 1.5’s . The Sansui 7070 is paired with Klipsch Heresy II’s and the 9090 has enough power ( barely ) to match well with my JBL 4313A’s on Sound Anchor stands . As one person stated of being dismayed after a few weeks , I concur . But with the modest prices for this gear , I can rotate and also include my vintage tube gear . I once ran the Marantz 2223 with pre out to my Dynaco MK III’s. So it was Oppo 105 to Marantz to Dynaco to JBL . Actually sounded pretty nice . I also have the brown braided speaker cables from the 70’s ( brand escapes me ). My next adventure is to restore the 7070 even though it sounds decent . If it’s a big enough improvement , I’ll risk doing it on the pricier amps. Cheers , Mike .
