I'll have to do some research.
I have attempted this cd-4 in the past, a friend owns a copy of it. I was unimpressed enough that I didn't bother keeping any files or continuing attempts at getting a recording of this when I had access to it. I'll ask my friend if he'll ship it along with some other records he's sending sometime soon so I can borrow it and give it another go....he doesn't have a demodulator so he'll probably have no problem lending it out.
I have borrowed a Q8 of this, I recall it being a more subtle quad mix, but I don't recall it being something I would call fake. Just subtle, which A&M was known to do for many releases. Although I think a track, or a few, may have been faked....I'll have to review my disc of it.
As far as cd-4 *completely* working....well....that's just not something cd-4 really does. It's a tricky beast. Between worn records, bad pressing, and such, it's not something that I've ever found to be a set it and forget it type of format. There have been combinations of equipment that have achieved superb results, but whatever equipment you're using, you're bound to run into aggravations many many times when traveling down this path of quad collecting. The best setup I've known to exist for cd-4 was Cai's, which produced some great conversions. And I know he went through a lot of trial and error to get the setup he landed on, and who knows if that journey would've ended there.
The marantz cd-400 is a great demodulator to go with. But stay away from the cd-400B. These days I have the common audio technica cartridge that is often mentioned as an easy to get cartridge that performs well, which has performed adequately for now. I was using a signet cartridge, which I can no longer find a replacement stylus for. I've had better luck with my linear tracking turntable than the standard pivot tone arm table, but I rather dislike linear tracking, too much noise of tone arm adjustments in quiet passages. I've tried to dabble in getting MC cartridges to work, but with no luck yet. My Denon cartridge almost did it, but....not quite. Some will say that MC cartridges aren't meant for cd-4 and will never perform right. Cai's setup was proof that isn't the case, although it took a lot of money to make that happen. Also, ortofon seemed to dabble in it, one of their head amps for MC cartridges has a setting with a filter to be used for cd-4. I've not gotten my hands on one of the cartridges meant for that head amp, and gave up on that and sold it off, so I'm not sure how that would have performed. I did find out my ortofon rondo bronze was not meant to pair with that head amp, which probably explains why I could almost, but not quite, get that one to work with cd-4. I'm expecting that cartridge to come back retipped next week, and have a head amp that should be a better match for it....so....fingers crossed.
