Whats on your turntable tonight?

That cd4 format was the reason the Shibata stylus was developed ages back.
While quad died an early death, fortunately the benefits of the Shibata ensured a long life.

Uber, I've read a lot of conflicting information about CD-4. You'll ruin the rear channel info if you use a stereo stylus, it's ok as long as you use fine line or shibata, it doesn't matter what stylus you use... confusing.  They play great with both my Denon DL-301 MK2 and my Kiseki Blue NS.

Yes a lot of misinformation out there, just about as bad as mono and stereo playback.

I do not own any quad discs so cannot comment on how well they may play on regular stylus.

If they play and sound good then surely that's all that matters.
