Tranquility Signature vs. Bryston BDA-1?


Getting very close to buying a USB dac. I think I've pared my choices down to dB Audio's Tranquility Signature or the Bryston BDA-1. I'll be using a Mac Mini as my computer. My music library is almost entirely redbook in AIFF format. I'm looking for natural sound quality from my next dac. Has anyone compared these two dacs?

I hear the new Burson DAC (with volume control), is wonderful and it's cheaper than both of the dacs you mentioned. Look into it.
Have you considered the W4S DAC2? I have no dog in this hunt nor have I heard the others, but I have lived with the W4S for 6 months now after selling my Dodson 218, and think it is a breakthrough product at a screamin' steal of a price.
