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.

Triangleserius - Thanks for the link to the dac comparison that I was looking to find!

Nglazer - I considered the W4S but found reviews between it and the Tranquility where the consensus seemed to be that Tranquility had better mid-range smoothness. I want the most natural sound from my next dac especially in the mid-range.
As an owner of the original Tranquility and having heard the Burson AH-D160 (dac with preamp) and a bunch of other dacs, I can say: Tranquility hands down, wonderful sound compared to the Burson. My two cents...
