96 kHz 24-bit super digital transfer
I have a new CD pressing of a recording from the 60s (Sonatas and
Paritas played by Grumiaux). The new CD pressing is:
96 kHz 24-bit super digital transfer
Does this mean anything? Other things being equall is there an audible
difference from the previous CD (I don't have it to compare).

>From your perspective, it really doesn't mean much of anything. The 24/96
means that the original master tape (analog from the 60's) was digitized
using an A to D encoder that uses 24 bits instead of 16, and samples at 96
KHz rather than 44.1 KHz. A lot of digital recordings, whether transfers from
analog sources or recorded live are mastered in this way. But this 24-bit,
96KHz master is down-converted to regular 16/44.1 "Redbook" CD for commercial
release. In other words, from a consumer perspective, this CD is just like
any other as far as your player is concerned. As far as it sounding different
from the previous release of this recording. I doubt if you could tell any
difference, but it's possible that by using newer, more modern equipment and
truncating the 24-bit quantization to 16 by "throwing away" the 8 least
significant bits, the new CD might have a little less low-level distortion
and perhaps more hall ambience than did the earlier transfer, but who knows?
Just being a more modern transfer might make more difference than anything
else. The art and sience of mastering and producing CDs has come a long way
in the last 20 years. I've heard modern re-masterings of CDs I bought 15-20
years ago that sound so much better than the early efforts that it's hard to
believe that they came from the same performance (most of the newly
re-mastered (for SACD) RCA Red Seals). On the other hand, I've heard recent
re-masterings of older CDs that sound just the same to me as did the
originals.

It means the analog master was transferred to digital at 96/24,
any mastering work was likely done at similar rates, and
the digital master was finally downconverted to 16/44 for delivery
onto CD.
Any audible difference is more likely to be due to the
mastering work -- EQ, levels, noise reduction, compression --
and choice of master tape, than to the transfer rate, unless
the previous digital transfer was badly botched. If previous
digital mastering was done entirely at 16bits, that too could
make a difference, if a lot of digital processing was involed.

More details would help!

Apparently, this is a remastered version of the previous CD that was
released in or around 1994.

In terms of what?
The ca. 1994 transfer was an AAD recording, which is to say it was
origionally recorded in analog (probably 15 ips analog tape), and
mixed/mastered in analog.

There's an implied remastering, which means that equalization and dynamics
processing during mastering might be audibly different.
