I am in the market for a new DVD player - haven't set all my requriements yet - but I know I would like to enter invest in a system capable of playing one of the new audio formats. The question is which one? I don't really want to start buying disks of a format that may not last the long term. And I really don't want to start buying disks of both formats. After listening to a variety of sources played on a variety of SACD and DVD-Audio players they both seem to offer incredible sound quality. Infact I was unable to tell any real quality difference between them so they are obviously both 'good'. With regards to backing of various companies then DVD-Audio seems to be backed by Panasonic, JVC, Kenwood, Onkyo, and Yamaha. SACD seems to be backed by Sony, Philips and Marantz. Pioneer seems to be backing both formats (and Sony seems to have a universal player out now - is this significant?). So both have reasonable support then - if opting for DVD-Audio should I be concerned that Sony (with it's massive music archive) is not onboard? What's the position of other large music companies, e.g. Universal? Can someone also offer advice on the actual differences between the formats? From reading a number of sources a brief summary seems to be (please correct as required!): DVD-AUDIO DVD-Audio seems to based on standard PCM that the current CD-DA format is albeit with a more Dynamic range. It also carries the advantage of the high capacity of DVDs (can dual layer DVDs be used?) meaning several albums can be put on one disk (but does this actually happen?). I also understand that several audio formats can be used on one disk, e.g. Dolby Digital, DTS, or MPEG (but again does this happen?). What about 'content' accessed when using a TV, i.e. coverart, videos etc - can anyone expand upon this? Also, as I understand it, DVD-Audio is ground up 5.1 audio reproduction. What about copy-protection - can I use a DVD-Audio disk on my PC? SACD SACD seems to be based on Direct Stream Digital Recording which (I'm told) provides for more accurate sound reproduction than PCM. I understand this is because the music is not compressed avoiding artifacts or missing information. SACD disks have a capacity of 4.7GB (equivalent to a single, sided DVD) - so capacity compared to DVD-Audio isn't a major concern I suppose. I understand SACD can accommodate separate stereo and six-channel mixes of 100 minutes each. This seems somewhat limited compared to the multi-format music types on DVD-Audio (is it?) SACDs also have the capacity to include extras such as album graphics, still photos etc (again do they actually do this?)SACD players are backwards compatible with conventional CDs (which I suppose would be useful for in-car use). What about copy-protection - can I use a SACD in my PC? So that is the information I have so far on the differences between the formats. Looking at the differences DVD-Audio seems the more impressive. Can anyone add/correct/expand on that? There also seems to be some dispute over a digital connection for the formats, i.e. how does one hook them upto a AV receiver? I read ouputting via the digital/optical out on the DVD player will not give the full multi-channel audio? Can anybody shed some light on this? Is a new AV receiver required? Can anyone recommend an online retailer that has supplies of each type of disk so that I can browse the respective catelogues for each format? Many thanks to anyone who can shed some light on this.
