Rare, well crafted and very homogeneous sounding amplifier with excellent dynamics. All semiconductors from Toshiba, with very good values for that time and innovative circuit technology for pseudo-quadrophony. I have owned this device for years and recently had it for overhaul, after which I was again strengthened in my opinion, I do not need another one!
