Hi all,I am trying to figure out why it seems to be so universally (pardon the pun) agreed upon that to play cd or sacd or dvd that one simply must have a specific cd/sacd/dvd transport. I can sort of see it on the dvd side with needing to put video elements into the same box. But for playing a cd or a sacd, i mean, what is the technical issue that makes it so different? A laser reading bits with one frequency or another depending on source then transports them to a d2a. Uh, so why is this difficult or sonically less likely to be as good as a dedicated player? Lets assume for arguments sake we are not comparing 200 dollar mass market players here but full on 'high end' ones like say Classe or Meitner or Krell or whoever your flavor is for a universal cd/sacd if not cd/sacd/dvd combo.
Regards,

There's more to it than just reading the disc. There are different, more +/or bigger chips involved. Different dacs, sacd chips...they all draw power, requiring bigger ps, for one thing...It's not really a mechanical issue.
the statement (that I believe originated from Stereophile) was a broad generality imo.
I don't think it was ever meant to imply that it was a truly dificult task to make a good universal; but rather to say universals aren't usually great players.. One man's observation.
It's just general, 'simpler is better' logic (or rant).

I remember reading that SACD uses variable pit width as part of its protection scheme. So the discs, while loosely based on the DVD platform, are physically/mechanically different.
"I don't think it was ever meant to imply that it was a truly dificult task to make a good universal; but rather to say universals aren't usually great players.."Couldn't those statements imply some causality? That is, if it were easy (or at least straightforward) to make a good universal, then there would be more of them around, capitalism being what it is.
It's definitely NOT simple. From an engineering standpoint, there are numerous issues. Different protocols, different data sizes, under-run, over-run... When you try to design it, the complexity may just be too much for the price point of most players. There are economic issues because of the size of the market for the item based on the price.
