EV-4 Matrix was also referred to as the Feldman/Fixler Matrix.
I used a EVX-44 back in the day but eventually moved up to a Lafayette full logic decoder. Sometime in the 80's I picked up three EVX-44's (probably on eBay?) and eventually sold two. I still have one NOS EVX-44 in storage - if anyone is interested, make me an offer I can't refuse. For more info, there's this thread: https://www.quadraphonicquad.com/forums/threads/decoder-electro-voice-evx-44.14311/Was EV-4 encoding / decoding any good. I don’t recall any sophisticated decoders with logic ever being released.

I found one last night on Discogs after the amazon seller phoned me to say he hadn't got a copy left (he was interested that it was a hidden Quad!), the Discogs listing said sealed, so might even be new, should arrive in the next day or so.Duncan , I think I got mine from discogs , u might try that route.
