THE MOST DESIRABLE, PERFECT eq engineered in history, ever. Picked it up new the minute it hit the market back in '92 and it's still part of my stereo system. Both functionally and aesthetically, this 10 band, remote-controlled eq still looks like something out of a sci-fi movie. No sliders, just pushbuttons to set every one of its 10 band per channel individually -preferrably from the listening position via its lavishly laid-out remote. Indications come courtesy of a fluorescent display which also has a perfect real-time spectrum analizer and fortunately none of the DSP bullshit so common in the 90s. The specs are so tight they squeak and I would trade it only for say a Cello Audio Palette, which will probably not be as versatile and aesthetically pleasing as this unit. It can memorize up to five user presets (useful) and has 5 factory presets (useless), a bypass button.

Does not have a gazillion of useless decorative functions but this is a good thing. The only contendor used to be the digital paragraphic Kenwood which had a more flexible array of both graphic and parametric adjustments but was a pain to use and the size of a receive oas oppossed to this slimline eq (slimmer than a cd player)

If you come across a mint unit, pay whatever the owner wants to charge because nothing comes close to it by a long shot except esoteric gear and believe me, I've tried them all !! This is the Rolls Royce of equalizers; they just don't make ANYTHING like it anymore and never will, so there's no reasonable amount of money anyone could possibly offer me to sell it.



re: GR-777

Whoa, I got one of these bundled with a Technics SL-1300 (only issue was a burned out strobe, otherwise mint condition) for $70. Having seen the reviews here and on the AK forums, combined with the crazy prices the GR-777 has gone for on eBay, and my personal experience (I'm thrilled) with this EQ, I guess I got really lucky.
