I like my AT15S, not exact stats, but a AT15Sa ? Has good specs with the Shibata. Just finding one in great shape is the trick. I believe I paid about $125-150 IIRC.

In my early experience, playing my first JVC/CD-4 recording, I found the sound absolutely "mind-boggling."
I haven't found the comment yet, but, IIRC, Greg Bogantz (developer of the RCA Quadulator CD-4 encoder) said that RCA used the JVC 4MD-20X CD-4 cart throughout the entire production run of CD-4 at the RCA Indianapolis facility.

Seems like it should be an easy question to nail down right -LOLAll right, y'all. I get that recommending a cart/stylus for CD-4 is tough.
But just go with it! Knowing there are some caveats to consider, what is a solid choice to start out with?
It can't be impossible, or nobody would be listening to CD-4...
Thanks.
Are all Dual 1225's made for CD-4?I was using a Dual 1225 turntable, made for CD4 it has a CD4 antiskating scale adjustment with a Grado Prestige Red cartridge and stylus. It worked and I brought it to a quad guys house who tested it with several hard to play records including a Cat Stevens and he agreed.
Im not currently set up for CD4 and using a different turntable but I would like to try that again.
Has anyone here tried Grado cartridges or the more expensive Ortofons?
Please list carts and styli that you recommend...The ideal upper limit for CD-4 cartridges is 50kHz to ensure a linear response to likely sideband frequencies. However, even a cartridge with response to 40kHz - 45kHz will work satisfactorily because the vast majority of information is contained at that or lower frequencies. If you can, shoot for 50kHz.

Thanks!I believe this is the post Doug G. referred to:

I hear ya, Doug. Problem is keeping all the recommendations straight, when they're scattered. The other thread isn't really targeted at that. This one is.I posted the ones I have in the "What's your latest Discrete...CD-4..." thread.
I didn't see Kirk's post before this.
The Dual 1229Q replaced the Dual 1229 in the company's line when CD-4 became a serious contender in quadraphonics. At that time, I was working for a dealer selling Dual.Yes.
The better Dual of that vintage is a 1229Q also made for quad. The regular 1229 is not designated it may not have the special capacitance wiring. Both models let you unplug the turntable cables and replace them but its the wiring in the tonearm you have to be concerned about.
The 1229s have a full size platter my 1225 is three quarter size. It was kind of the budget model in the line. But it can be found cheap. They are driven by a rubber wheel no belts.
There may be a couple later model Duals made for CD4. Look for a CD4 adjustment on the antiskating setting
Carrier Crosstalk Considerations in the CD-4 System - AES Journal July/August 1977
Regular production CD-4 records (no special test records needed) can be used for this test.
I haven't tried this method, apparently a Digital Audio Workstation can be used (along with an amplifier to bring the cart level up to line level for the PC).
The limiter in a CD-4 demod can (mostly) compensate for poor frequency response in a cart, but not poor channel separation above 15kHz (where the FM carriers are).
