Shm recordings

[Alrainbow]

CAN someone explain who SHM is ?
I have many of there items sacd cd rips , downloads
while they are not perfect what I can say is most is very good in quality far better then Hd tracks on many.
I own so many rolling stand albums most be over 40 or so if I count doubles. Many analog downloads from above mentioned all kinda stick lol but there is stuff on there that is not on SHM. complies of greatest hits and so on.
Best of stones I ever found hands down.
Thanks in advance

SHM is a different compound to manufacturer CD's and SACD's made in Japan. This does nothing to the sound....

The difference you are hearing is they are mastered differently.

BRUCE
thanks but it's all it is.??? Not goofing on Hd tracks or others
but it's a world order above on many why wouldn't the others care then ? I. Mean using The Rolling Stones as an expample
most of what I own is truly a polished turd.

That's all it is.... SHM stands for Super High Material. If you take a regular Aluminum CD and a SHM CD of the same mastering, it will sound different because of how your player/transport sees the pits. But if you rip both to hard drive, they both sound (and measure) exactly the same.

Now the thing that sets SHM CD's and SACD's apart from the rest of the world is the different mastering by Universal/JVC. Most of the time they do a flat transfer with no EQ or Compression to get in the way. If they do use it, it is done very sparingly. This is what the audiophiles like!

The same can be said with Glass CD's. I purchased a couple of these (at $1400 ea. !!) and compared them to their regular "Aluminum" counterparts. They sound differently because of the way the player/transport sees the lands/pits, but if you rip both of them, they are exactly the same! Been there... done that!!

Interesting. I have a friend who owns several SHM recordings and has trouble at times getting his CDP to read them. I owned only one. I purchased just to see what they were like. It played on an old CDP But I didn't like the sound of that particular recording. When I bought my Bluesound Vault 2 it would not rip the SHM.and commit to server storage.

[Alrainbow]

Very interesting , I play my shim,s from a server not the physical disks as I like the sound of my lampi over the msb that I need to play SACD,s . It sure sounds much better and thanks for why An a,zone journey that ends in simplistic end . Makes me want to find the pepole who master our non shim and smack them in to head lol.

[Alrainbow]

Did you try any of the files I posted on here. The one from tonight is an analog master what a great sound

[Bruce B]

Sorry, have not gotten the chance to listen to them. Been busy the past couple of days doing tape transfers

[Alrainbow]

Pm me when you have some time I would like your opinion. Analog people don't seem to hear like digital People lol.

Bruce, I get what you are saying but not what you are saying. How does ripping overcome the reading issues for the regular CD? Aren't those problems captured too whether its playback or ripping?

No Myles... take Exact Audio Copy. That takes forever to rip a CD because it goes back and forth to each sector and compares it to make sure it gets everything exactly correct. The error correction software in a CD player is not as robust.... not to mention the jitter issue. Jitter is no issue with ripping a disc and transferring files. That's why Gold CD's, burnt vs. stamped and Glass CD's sound different when played back real time.

Take the advert of the SHM CD..... taken from Wiki:

SHM-CD is a digital optical disc data storage manufacturing process. It is an improved compact disc product with the greatest change being a different polycarbonate material that allows more precise physical representation of stored bits during pressing and less laser scatter during reading. These improvements aim to facilitate playback by producing fewer errors and potentially better sound quality. SHM-CDs are played on a standard CD player.

The easier you can make it on a CD/SACD player, the greater potential it will sound better so it doesn't have to work as hard with error and jitter correction.

OK thanks for the explanation Bruce!

Years ago I had some sampler discs from Chesky where he tried different combos:

Al + polycarbonate
Al + Zeonex
Au + polycarbonate
Au + Zeonex

The discs all sounded different but I wasn't sure that the materials weren't just compensating for digital's sound back then.

When Winston Ma produced a demo CD titled "Passion" for Mercedes-AMG GmbH in 1999, he was tasked with producing a CD with consistent high quality. The CD's were produced with a Block Error Rate (BLER) average of less than 10. They sound really good.

[MylesBAstor]

Yes, I have that disc!

Back then I lusted for an AMG. When I bought my AMG last year, the first CD I played in it was Winston's.

Your car is a very special car especially for its price and what a great car it is. My son has a simple s550 what a damn good car it is as is. The AMG models I had were really for speed and LUXERY as long as it did not impead sport lol. Enjoy only better is staus not really improvement over mazzarotti and Ferrari too loud and no luxury added too much attention too.
at the end i drive a Elantra and a gmc dinali pick up. Wife has a benz r550 no loner made its limo type she used for dog shows.
Bruce thanks for always honest knowlidgible inout.
