Hello & Welcome RPG!
Nice intro & interesting history. I am delighted that someone in their early 20's is still discovering the fun side of surround sound & music. When you get a chance how about sharing what music you like & more details on your current gear? You are in the company of enablers, er, friends that will certainly be glad to help you expand both. :devilish:
My current setup is a Realistic QA-681 Amp with a pair of Baby Advent IIs in the front and some Polk Monitor 40 Series IIs in the rear. Turntable is a modified AT-LP120-USB (the usb and preamp board has been removed) with a VM540ML cartridge. For quad vinyl decoding I have a Sony SQD-2070 for SQ and a JVC 4DD-5 for CD-4. The rest is a Panasonic RS-845US for 8 tracks, a JVC KD-65 for cassettes, and a PC for digital audio. Switching is done by some component video selectors for quad sources and a DJ mixer for stereo sources.

The music I listen is fairly diverse. One day I might be listening to classical and the next day it might be metal. I would say overall most of what I listen to is 70s-90s rock. During the past month I've been playing the Allman Brothers at Fillmore East a lot as I recently got both the quadradisc and the blu-ray set and currently as I write this I am listening to the Doobie Brothers Quadio.

Is the 540ML working well for CD-4?

I currently have about twenty CD-4 records and almost all of them play perfectly with the 540ML. The one giving me the most trouble is Gordon Lightfoot - Sundown which I have two copies of and they both distort but neither is in very good shape. The others two that give me trouble are Elvis Aloha from Hawaii Which distorts some but isn't as bad as Sundown and The Best of The Doors which doesn't distort but doesn't seem to separate very well. The rest of my CD-4 records have good separation and either don't distort or if they do it's barely noticeable.

Thanks, I assumed that the 540ML is good for CD-4 but hadn't really heard much from from actual users, I have 440MLB which has been trouble free with most CD-4s.

I'm in my early 20s so I missed out on quad by over 20 years and was too young to care when dvd-a and sacd happened. I started collecting records and tapes I was probably 7 or 8. Back then I had an old realistic amp I bough at a yard sale with a dead channel and a 4 speed record changer I got from my grandpa's house that had some issues but it was good enough for me to play the 78s and Herb Alpert records I was buying at antique and thrift stores. I heard about quad records at some point probably in my early teens but didn't know much about them. My first real encounter with quad was when we were visiting one of my dad's friends from college and he showed us two quadraphonic 8 track tapes but didn't have a way to play them. I had recently started collecting 8 tracks and had no idea there were quadraphonic 8 tracks so I thought it was the coolest thing. After returning home from that trip I found the quadradisc of Danny Davis' Nashville Brass - Bluegrass Country which was one of the two albums I had seen the quad 8 track of (what are the odds of that). I was obsessed with trying to play it after seeing a video of someone using some sdr software to playback the carrier on a cd-4 record. The attempts to play it didn't go too well but I thought it sounded kind of cool despite being a distorted mess. Eventually I also found one SQ record and a crappy decoder but I really got into quad when on vacation about two years ago I finally found some quad 8 tracks at an antique store. There were probably seven or eight of them but I only bought two because I figured I would never find a player. When I got home I went on ebay and ended up wining a JCPenney quad 8 track player for only about $30 shipped and I really regretted not buying all those quad tapes. Since then I have been built up a decent collection of surround music on various formats.
