Alright, this is just my opinion and I consider myself to be a noob like you do. If you listen to a lot of rock and rap, then I would urge you to consider getting a Redbook only CDP. All of your favorite artists will be releasing Redbook CDs for sure. As for whether they will release a high resolution DVD-Audio or SACD offering of their latest albums, well...don't hold your breath for too long. Those high rez discs are coming but they're coming like molasses (IMHO).
DVD-Audio and SACD are basically high resolution formats. 24 bits. 96kHz or 192kHz. Far greater dynamic range (I can't comment on the numbers). Basically, it's like listening to High Definition music. Have you ever walked into a BestBuy, Circuit City, or some specialized electronics store? Have you ever watched those big, expensive, flat screen High Definition TVs? That is a good albeit rough comparison of the concepts behind DVD-Audio and SACD. I briefly owned a DVD-Video/Audio player, a cheap one I couldn't figure out, and two DVD-Audio discs. At first, I couldn't perceive an improvement. Later, as I got closer to selling off my DVD-Audio player and discs, I heard the difference. It's like night and day. Listening to DVD-Audio is like getting so close to Tupac's voice that you can tell what he ate for lunch by the smell of his breath. Ok. That's a hyperbole but I think it's true.
I'd recommend you sit down and ask yourself a few questions before you do anything with your money. First, ask yourself if you just want to listen to your favorite rock/rap artists' latest albums without having to fuss with those high resolution thingies. Second, do yourself the favor of doing your own research into specific products.
Next, please take the time to seriously consider buying a Redbook only CDP like the NAD C 541i. I got it. It's da bomb yo! Seriously, it sounds...very good. I got it for $457.00 dollars through YAWA Online. Check them out. Very reputable reseller of NAD gear. Go to the NAD website (
http://www.nadelectronics.com) and a couple of other websites like Stereophile, The Absolute Sound, Audiophile Audition, AudioREVIEW, HI-Fi Choice, and What Hi-Fi? Do a search using Google and just punch in the names that I listed and you'll find the websites. Then, use each website to do another product search for the NAD C 541i CDP. Good stuff. Big performance per dollar value CDP. You won't be disappointed.
As for the "future," I would say hold off. Right now, there are a few DVD-Audio/SACD titles but the number of new pressings is growing steadily. However, I think that the release of DVD-Audio/SACD titles is not going fast enough for me. As for the hardware to play those kind of discs, I can't really comment. I can say that I do like the idea of a "universal" player. It's a DVD-Video, DVD-Audio, SACD, Redbook, CD-R, CD-RW, MP3 CDR, DVD-R, DVD-RW, and maybe HDCD player that costs megabucks but the problem is that it's too expensive. Anyway, I hope that all this makes sense to you because it doesn't make any sense to me.
