Review: Prism Sound CALLIA USB Audiophile DAC and Pre-Amplifier

I reported on my positive impressions of the Prism Sound Callia DAC from RMAF and the the New York Audio Show which is unusual as I typically refrain from making comments on sound at shows. But the Callia intrigued me into it. If you look at the dates of those reports, you'll see it's taken some time to get a Callia here. It was worth the wait.
