I just recently completed my build (14 hours - thank you very much) - and I'm now looking for the best way to play lossless FLAC or Apple files on my STA-120.
For testing I'm currently feeding from the headphone jack of my iPhone (works for testing) - but I'd really like to come up with a better way to feed music digital into my amplifier.
Some Options I'm considering:
1) A mac mini with a USB DAC wired into the Amplifier. I could then remote desktop to the mac mini and play lossless Apple Audio files out to the Amplifier at 24 bits/192KBS (the upper limit of the best USB DAC I've seen).
2) An Apple TV wired via Optical to Optical DAC Convert Box with stereo out. This would be limited to the quality of Airplay 16 bit/48 kbs.
3) A Sonos or other wireless audio system. This would be limited to 24 bits/192KBS.
What have you folks used with success? How much quality is enough? Any thoughts on using a digital home theatre receiver (like the Denon 1912 or 1913) as a "pre-amplifier" for digital music?
I'm not sure I want to go completely analog (LP's with a pre-amp) - but I would like to play my audio with the highest quality possible.
