Maybe this will help.
>"Since loudness measuring is based on an algorithm that builds on a study of subjective perception, in theory, program material that complies with the determined LRA and Program Loudness of a certain broadcast standard can in fact overload if normalized the traditional way (quasi-peak or sample-peak). Therefore, normalization is also part of many broadcast standards, and to comply, broadcasters must use a true-peak meter.
Many loudness meters have a built-in true-peak meter, and what sets the true-peak meter apart from sample-peak meters is a special algorithm - donated by TC - that not only looks at the actual samples, but also inter sample peaks. In effect, the true-peak mater can unveil peaks in between actual samples that would otherwise cause distortion. Therefore, a true-peak meter actually 'goes beyond 0 dB'. A reading using a traditional sample-peak meter that displays a max of e.g. -0.2 dB could go as far as +3 dB on a true-peak meter reading.
Please note that this does not indicate acceptance of exceeding 0dB on a true-peak meter, but it provides a more precise reading that helps in normalizing program material without compromising the quality of the audio. As an example, the max value of normalized program material according to the EBU R128 standard is -1 dBTP (dB True-Peak)."

This is all of interest I could find so far, a feature of an off line measuring system:
True-Peak Warning - Ensures Audio Quality Downstream (data reduction, codecs, converters, etc.)
Thanks Reuben! They have a knowledge base page I will have to navigate through.

Anybody heard the DSD version of this?
There's a DSD version?
My Sony HAPZ1 coverts the PCM version to DSD, and it sounds very nice.

There's a box set called High Vibration.
I'll be able to let you know how it sounds in the next couple of days.
Forgot about that Japanese import.
Yes, please let us know what you think.

I currently have the Yes album, 90125, and a couple of songs from Big Generator on DSD, and they all sound pretty good.
Have you ever compared PCM to DSD vs DSD on your HAPZ?
I have never compared a hi-res PCM vs a DSD of the same album. Just starting my collection, so a little early to start building multiples of the same album in hi-res, although I think the next hi-res versions of Yes I will buy will be some Steven Wilson remixes, so those will be my first multiples of the same album.
If I ever get an album in both hi-res PCM and DSD, then I will post a review.

The DSD version sounds pretty good. Forgot about Simon & Garfunkel at the end . . . which is to tell you I haven't actually heard the original CD, probably since college (early 90's).
However, I have heard it on vinyl with a friend's system (that's completely different from mine (think large Darth Vader Wilson speakers & large solid state amps)). The DSD doesn't sound quite as good as the vinyl, but it's pretty close.
"Look for America" wasn't on the original album. It's a bonus song, and a good one. It was originally on "Yesterdays."
I have some opinions about the way the 24/192 "The Yes Album" sounds, but this version of Fragile sounds really close to vinyl to me.
Keep ripping those SACDS.

Meant to mention in that last post -- if you don't have the album Anderson, Bruford, Wakeman & Howe it is WELL worth finding. Don't quote me on it, but I believe it came out in '89 when the 'new' Yes was alive & kicking.
Howe's playing on it is absolutely incredible.
It is by no means hi-rez or an 'audiophile' recording, but if you like Yes you will like it. In fact you will probably love it.
Thanks LTS. I'm aware of that album, but I've never heard it. I'll order the CD this week. No doubt about it, Howe is a true master of the guitar.
