[The hidden question here is: I'm looking for an external USB or FW DAC for my bedroom 2.1 setup. Budget is $300-ish, give or take. Leaning toward AudioEngine D1, unless anyone has any better ideas] I'll keep this as short as possible: I'm looking for an external DAC for my bedroom 2.1 setup (Arx A1s, an eD A3s-250, and an older Pioneer Receiver for power). So that's simple enough. But eventually, I'm likely to combine this with my living room 5.0 setup (BA lynfield towers, etc). So my question is: Should that alter my choice in DAC? It seems to me the D1 will only output 2 channel audio. That's certainly fine for the bedroom setup, but what about the livingroom HTPC setup? Does anyone run "multi-DAC"? I'd be more than satisfied with the D1 for music and something onboard from the HTPC for 5.1/DVDs/etc, but is doing something like that klugey? Does this make any sense? Cliffs: 1. Need external DAC for music 2. Building HTPC 3. Can you get a 2.0 DAC to play nice with a 7.1 HTPC, or do I need a 7.1 DAC? BONUS QUESTION: What's a good 7.1 external DAC? =] Thanks in advance!
