Absolutely great sounding hitachi set! completely original from the first owner! I tested it on extremely high-quality (vintage) speakers, Tannoy Arden / Eaton as well as on VOTT A7 with 416-8b / 802-8b (511 horn) alnico. a huge stereo image accompanied by emotion, everything is tangible in the display! My tubes do that better and cleaner (Qaud II completely overhauled) but this comes very close! Also aesthetically it is all in a very pleasant condition, see the photos! Will be packaged and shipped extremely well!
