Digital Audio Server

You definitely want to use a higher-end sound card. I recommend the audiophile 2496 from m-audio. The quality of the pci card vs a usb connection is immeasurable. An inexpensive set up is to pick up an older Macintosh tower on ebay just make sure it’s a model with Firewire connections and that it’s Airport ready (for wireless) -- you should be able to get one for around $300. Buy the sound card ($150). Then buy external Firewire hard drives to plug into the tower. Buy a wireless card ($60) buy a wireless router ($50). Apple makes software called “apple remote desktop” which allows you to control computers remotely and wirelessly (around $300).

Here’s my set up. I have my old tower as described above running Apple remote desktop with no monitor. It’s just sitting next to my rack plugged into my pre amp. I control the unit from anywhere in my house from my laptop running the Apple Remote Desktop client software. Your entire music collection is only a click away.

I would run a PC platform. Mac no longer maintains a software advantage and certainly doesnt have a hardware advantage. As a matter of fact, Macs use converted PC technology in every hardware aspect except for CPU and motherboard. Upgrades, parts, and initial purchase will all be cheaper with the PC platform.

M-Audio makes very popular soundcards at attractive prices. My recommendation would be use an outboard DAC and feed it via the Digital out (spdif) from the computer. So the ultimate soundcard wont be an absolute. Of course if you dont plan on a DAC, then the better cards will provide better analog outs. I use a lowly Audigy 2/Theta DAC at the moment and cant really complain.

Memory is more of persoanl preference. Basic sound reproduction doesnt require a lot of system resources.

If this server is to be located in your listening area I would recommend a quiet approach. Maybe a low core voltage CPU that wil run cool and wont require CPU fans or case fans. Whirring fans you probably dont want. Check out the powersupply as well, they usually have built in fans.

As of right now I use an old program called "Siren" it was from a sound engineering software company called "Sonic foundry." They may still make it, it is OK. There are probably better music serving programs available now. It can call up the names from the internet so you dont have to type them all in. I think that is a paid service, though I am not sure.

I hope this helps...

I forgot to talk about hardrives. Sorry.

Bigger is better in this case. Music is just under 10 megs a minute in its native format. Just as stated above 600 CDs will require a lot of storage, probably multiple harddrives. I would recommend tried and true IDE ADA/66/100 Harddrives. Ther is no need for cutting edge technology, music data transfer wont require high data transfer rates. The best deals on HDs are in the 60-120 GB size right now. Although, they do make bigger ones, they come at a cost.

I'm running a g5 with iTunes, using the digital optical out via an audioquest OptiLink 1 (12m) to an external cal-audio sigma DAC...

LOVE it... and i've got almost 2000 songs (all AIFF / uncomressed, ripped from my CDs) on a 160gb drive. g5 is AMAZINGLY quiet (don't even know it's on except the little white light) and apple's iTunes works w/ a cheap $25 remote-IR unit (pre-configured and all) so I can control it all from my Rotel (preamp) remote which is nice (aka don't have to touch the computer). To top it off, a sub-$20 adaptor let me run video out of the mac to my TV so i can even scroll thru songs etc - it's like having an AudioRequest at a 10th of the price (for that capacity). Plus, i can easily convert to m4a for my iPod :D

AIFF and WAV are virtually identical. Both are PCM, bit rate encodable, and sampling rate flexible.

Uncompressed each minute of music (AIFF or WAV) takes approximately 10 megs.
