I just got on this forum today because I was looking for a 2chn amp for my kg 3.5's, but I write music also. I have the M-audio Omni Studio, which is a delta 66 sound card with break box for connections and control. As far as surround goes, I'm not familiar with the newer "surround" cards. I can tell you that in the music writing world, M-audio is very well respected. M-audio is actually a subsidiary of Midiman, although they're starting to go by M-audio. Another great product from the same group is Propellerhead. If you've ever heard of Reason, that's who makes it. The group at M-audio are very inovative and have their sh*# together. They make good products and great prices. As far as soundcards go, the sound card is only as good as it's driver. M-audio has awesome drivers. Don't buy any card that doesn't have an ASIO driver, you'll just be wasting your money. Also, don't buy Soundblaster!!!! I repeat, do not buy Soundblaster!!! Crappiest, most commercialized card out there. I don't use my computer for home theater so I don't really know what the M-audio cards sound like. You can bring the signal out at 24bit/96khz. It's not really up to the card to decide wether or not it's surroud capable, technically. It's up to the software. Most of the music writing software out there are starting to incorporate surround mixing. I use Cubase SX. It's not recommeded for the beginner, but it'll almost anything you can think of. If the software mixes in surround you don't need multiple outputs on the soundcard. So you could use to audiophile 24/96 to encode in surround. Cubase will export a surround mix, but to burn it to disk, you need encoding software. It's a bit pricey right now, but give a year. Surround is here to stay. In the future, all music cd's will be surround capable. Most studios now days are mixing/mastering in surround already, although they don't release it. That's because they want to be prepared for the future. Here are a couple of software suggestions for encoding in surround: Minnetonka's Surcode Universal or Audio's SmartCode. As far as SACD or dvd-a? Forget about it. Can you say proprietary technology? Just in case you didn't know, SPDIF is the original format for a cd, which is 16bit/44.1khz. SPDIF stands for Sony Phillips Digital Interface. Sony and Phillips teamed up to develop the cd, so there's you inventors of the cd!!! Sony and Phillips have teamed up again on the SACD. I would bet on SACD over dvd-a since you have to have a different player for either one, plus SACD has a higher sample rate. Anyway, I thought some of this might be informative for some. Have fun with your equipment!!!
