What is this blu-spec CD format compatible with s

BTW: There are a few reasonably priced Blu-spec sample sets that contain 2 CDs; same songs on both discs, one Blu-spec, one non Blu-spec. These sets will give you a very good idea what Blu-spec brings to the table. You could then judge for yourself whether you want to to put out the extra funds for Blu-spec discs. I believe these sample sets are available in rock, jazz and classical flavors.

Blu-spec and Blu-Ray are two different things. Blu-spec can only be played on regular old CD players. Blu-Ray discs require a Blu-Ray player. Blu-Ray discs also cost much more than Blu-spec CDs. And, there are very few titles available on Blu-Ray disc.

Blu-spec CDs I have heard sound very good. I have never heard a Blu-Ray disc and it's very possible that I never will.

i've toped 50 titles so far...no disappointments to speak of. some have 'runs as small as 1200 pc....all are limited.

Ok, better understanding of what they are. But are they really any better than a standard CD? If so how much? Seen a series coming out by one artist that I would not mind having. Just have to justify the extra over the regular CD. And I do not have the special player so do you gain any extra? Or I just run through the blu ray player?

Mostly I just take and rip to my Mac and then run through the D/A converter so what do I gain?
