In Reply to: RE: Rip from a physical CD. posted by PAR on April 23, 2021 at 15:16:41
See my reply to Daverz. I thought he was talking about Qobuz.
The only problem I've encountered with CDs containing some form of watermark or copyright protection is that my Rega Apollo CDP will not output a digital signal (SPDIF or Toslink) if the CD is copyright protected. I've had to rip those CDs to hard drive and then burn a CDR disc. Plays those discs just fine.

How do you know that those discs had either watermarking or other DRM? Record labels do not advise of the fact on the packaging. One thing that is clear is that if a CD so treated cannot be read by a standard redbook player then the record company would go out of business pretty quickly. In any case watermarking cannot be removed by making a rip as it is contained within the music data and so will be in the rip as well. Anti-copying DRM should mean that no rip could be made at all.
I believe that you are incorrectly attributing the cause of your Rega's failure to play the disc. It is more likely to be something either optical or mechanical that prevented that particular player's mechanism from reading ToC.

I wasn't clear enough about the differences between analog out vs digital out. The Apollo played those discs just fine when using the RCA analog output. The Apollo would not output a signal using the SPDIF connection.
Thanks for the clarification. I haven't come across DRM that does not allow an output at all, rather that either the (ripping, recording) device attached will not accept the data stream without a key to authorise it or where the stream is encrypted and a device without matching decryption cannot recognise it.
Anyway, as I mentioned, the object of this type of DRM is to prevent ripping , which in fact you were able to do. I believe that Sony released a lot of CDs like this some years back over a couple of months but had to abandon it due to the public reception when it was found that the system introduced root code to the ripping device e.g. computer, which disabled it when ripping of the disc or others similarly equipped was attempted. Incidentally you should be able to see if the CD is protected by inserting it into a computer optical drive and selecting "Properties".

Most of the CDs that wouldn't output digital were Sony CDs. I used dBpoweramp to rip them so they must have figured out how to disable the DRM encoding.
are there non-physical CD's? metaphysical disks or quark media?
I knew what Dave meant. :-)
It is getting more complicated now that we have CDs, CD rips, CD quality downloads, and CD quality streaming. So yes, it is a bit metaphysical. I'm looking forward to extrasensory media; no more stereo systems needed.
he should have mentioned the redbook standard just to be sure
oops, gotta go let the physical dog in ... the analog version
he's a woofer that's not a speaker
"Physical CD" was short for "Rip from a CD that I have in my posession, not a download."
