Early 80's - late 70's best audio products

I still use (after 30 years) and have just purchased two more pairs on Ebay, of Yamaha HP-1 and HP-2 headphones. Together with the Yamaha TC800D (wedge shaped) cassette deck these were all designed by the legendary industrial designer Mario Bellini. The HP-1s have an effortless, fatigue free and open sound. Most of all, they are all beautiful to look at as well as use. That makes a difference!
My DBX 118 dynamic range expander/compressor was the most invaluable addition to my hi-fi of that era. I compressed records when dubbing to tape and expanded on playback to restore dynamic range and lower the noise floor. Brilliant. My amp was a Pioneer (silver) SA7500, average, but still in use today and well worth a listen.

ARC D79B Tube Power Amp,and ARC SP-11 Preamp,Koetsu Rosewood Phono Catridge,Oracle Turntable,SME V Arm,Quad ELS 63'S or ,Soundlabs A1,RH Labs Subwoofer.If I'm forgetting anything I will post again.

76doublebass has it right - that would still be a killer system today (although I might get triple stacked original Quads!).

Joe Grado invented the moving iron and moving coil not the moving magnet.
He used moving iron on all his cartridges,and are used today by his nephew John at the helm.Old Joe just enjoyed the royalties of his MC patent.

I think the Rega planar 3 deserves a mention. It's still competitive in its price bracket 20 years later.
