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.

Welcome to the forum :hi

Hi Everyone,
I'm 61 years old, so it's been awhile back in time, but I remember my first stereo when I was 12 years old (1972) being an inexpensive 4-channel/quad system with an 8-track player as the source of the quad sound, and can remember how cool that quad demo tape sounded when we first set that stereo up! That system was gone a few years later as I traded up for better 2-channel components all the way into the 1990's in search of that elusive "best" stereo sound (at least for what I could afford!). After the 1990's I bought mostly home theater stuff only. I currently have a new hobby of repair/restorations of 1970's (mostly) stereo equipment. I recently I obtained a Pioneer QX-949 in need of repair/restoring. My intention is keeping it to set up a quadraphonic system for playback of old SQ/QS and Quadradisc LP albums (and also maybe also some Reel to Reel content if I can find a nice machine in need of repair?). I joined this forum to see if I can get some help/advice with some questions about integrating newer components into this system? Maybe take advantage of the recent releases of old quad 4.0 content on DVD-Audio and/or SACD? I will search to see if I can find links recommending some solutions for this. Any help along these lines is appreciated! Thanks in advance!!!

Greetings & Welcome Surf!
That's an interesting history... an favorable impression of quadraphonic's when you're 12 yo old & it lingers. Until it comes back, blasting, billowing, bursting forth with the power of ten billion butterfly sneezes!

Anyway you'll find lots good folks & good info. Somewhere there is already a thread posted about the repair on the 949 including the level scope. Poke around & make liberal use of the forums search engine. Looking forward to your future posts.

Hi All,

I've been a member for awhile now, but I wanted to post this before any more time goes by! I remember when quadraphonic came out when I was in high school but I didn't know anyone in my circle of friends who had a system. I had one album in Quad, the Doobie Brothers Vices...Habits album that played fine on my stereo at the time. Decades later in the 2000s I had accumulated a few discs that happened to include surround mixes: the Beatles Love, the SACD of Townsend's new mixes of Tommy, and the SACD of the Beautiful Mind soundtrack. I put together a 5.1 system in 2009 for music playback and I've been at it ever since. I didn't really start collecting multichannel discs avidly until a few years ago. I added an OPPO last year that plays back my 5.1 FLAC albums beautifully. I used the Penteo plugin to convert all of my stereo collection to 5.1 FLAC albums as well. Anyway, you guys have helped me tremendously in so many ways on this forum!

Hello everyone. New to the forum, and yes I do have a quad system from the mid 70's. By 1980, I had boxed it up and since I retired in 2020 in May, I decided to resurrect it and bring it back to life. Here is what I have for equipment:
Pioneer SX-525 Receiver
Pioneer QL-600 Quadralizer
JVC 4dd-5 CD-4 Disc Demodulator
Audio Technica AT12s Cartridge and Stylus
Rega 1 Turntable
Yamaha CD-S300BL CD Player
Denon_DCD-610 CD Player
Sony CDP-315 CD Player
Teac A-4300SX Reel to Reel
Nakamichi BX-150 Cassette Deck
Nakamichi MR-2 Cassette Deck (2x)
Onkyo TA-R301 Cassette Deck
The cassette decks were just added last year. I had some old cassettes that I recorded back in the 70's and early 80's and wanted to play them. I also have a Robin Trower Bridge of Sighs that still works.

I had to buy a new turntable last year which is the Rega 1. My old turntable, a Technics SL-L20 Linear Tracking Turntable which is a P-mount which would not work with my Audio Technica. cartridge.

My Pioneer SX-525 had a few issues I had to fix. I had a couple of burned out bulbs, and I had to replace a cap that would cause a "thumping" sound when adjusting the bass control. Got those fixed and got the unit cleaned up. Looks new.

I really wanted a 4 channel reel to reel, but the prices are quite high so I settled for my 2 channel Teac A-4300SX that I picked up via Face Book market place. I required some major cleaning, and I had a tech replace about a dozen caps. Got it cleaned and lubed. I also replaced the 2 wooden side panels with real wood.

As for quad LP's, I have the following:
AMERICA - HEARTS
DAVE MASON - ITS LIKE YOU NEVER LEFT
DOOBIE BROTHERS - STAMPEDE
DOOBIE BROTHERS - THE CAPTAIN AND ME
EAGLES -ONE OF THESE NIGHTS
FRANK ZAPPA - APOSTROPHE
GORDON LIGHTFOOT - SUNDOWN
GORDON LIGHTFOOT - COLD ON THE SHOULDER
JACKSON BROWN - LATE FOR THE SKY
JEFF BECK, TIM BOGERT, CARMNE APPICE
JETHEO TULL - AQUALUNG
JOE WALSH - THE SMOKER YOU DRINK THE PLAYER YOU GET
MIKE OLDFIELD - TUBULAR BELLS
PINK FLOYD - DARK SIDE OF THE MOON
RICK WAKEMAN - JOURNEY TO THE CENTER OF THE EARTH
SANTANA - SANTANA
SEALS & CROFT - SUMMER BREEZE
SHOSTAKOVICH - SYMPHONY NO 15
THE DOORS -BEST OF THE DOORS
CARLY SIMON - NO SECRETS

Looking back now, I wish I would have purchased more quad LP's, but when you're young and foolish (i.e. in your 20's) and have multiple hobbies, money was tight.

Forgot to mention my speakers - they were custom made with my buddy. I wish I would have kept the info on them.

Welcome. Nice to hear about original owner quad equipment coming back out of the closet! If you keep your eyes open in thrift stores and record store dollar bins you can still turn up quad LPs at rock bottom prices, especially middle-of-the-road and classical (as you list Shostakovich).
