SACD & other Formats

High end Bob. Could you describe the improvements with your EMM XDS1.

SACD is the way to go IMHO. Buy the Oppo 105 and have Modwright instruments give it the full mod. The player becomes a giant killer in multiformat players. I have one as well as the 25k EMM labs XDS1 they are closer than they should be for the price difference."

Why not just buy a player that was made right the first time, like an Ayre 5 series universal player, or something similar? You will also be wasting money on video features that will never be used.

The SACD direction looks appealing because there seems to be a market push for the product.

I am running a Rega Osiris amp and the Rega Isis is very attractive given my amp and the balance of my equipment but it doesn't read SACDs.

I understand the Hybrid SACD have a SACD layer and a red book layer. Assuming both layers are from the same mastering could a CDP like the Isis reading the red book out perform or be as good as say a Modified Modwright reading the SACD level?

Do people buy SACDs for the red book layer? in theory it should contain the same mastering.

I think the biggest mistake made with SACD, was to allow both single and dual layer discs. If Sony only allowed for hybrid discs, people would have been building their SACD collections even if they didn't know what SACD's were. The format may not have failed.

As far as quality goes, that's something you have to decide for yourself. I thought CD's sounded better on my Wadia than an SACD of the same recording, did on my Sony 9000ES. But its a judgement call that you have to make.

Yes, but unfortunately most SACD's are single layer.

I've read interview with Roger Sanders. He believes that red book CD format is perfect and vinyl is inherently flawed. He quotes Nyquist etc. He forgets that Nyquist theorem applies only to continuous waves and fails short with short samples especially of high frequency (like cymbals). SACD contains 4x more information and is collected with weak or no antialias filters making for better pulse response. It is difficult to compare two, since SACD players are often not the best redbook players.
