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'd like to concur with Robert of Ridge Street Audio.

I've owned the UltraFi iRoc, listened to the UltraFi MusicStream, the Tranquility, the Tranquility SE, and now the DAC-41, and I will be receiving a modded power supply DAC-41 in a few days.

Of these DACs, the DAC-41 far and away excels in my three systems, and if you are buying your first DAC, I suggest that you go with one. One thing I'd like to note, for some reason, the DAC-41 improves over time in all aspects of audio quality: and I mean months. Why this is, I have no idea, but they do... just my experience.

I own a Moore DAC-41 (transport is a 2011 Mac Mini) and a modded Oppo 95 (mainly a DVD spinner, SS mod by ModWright). I believe the Oppo will have some similarities to the W4S DAC as both use the now-ubiquitous Sabre chip.

I spent an evening comparing the two as I wanted to make sure the DAC-41 was earning its rack space - if I could simplify down to a single digital source, super.

I can hardly say "compare" because the differences are so drastic. I have thought the Oppo was a great digital source in the 6 months or so I've had it, and better after the mods.

But, on the acoustic music I listen to (40s-60s jazz mainly), the DAC-41 is honestly in another musical league. The DAC-41 has a midrange far more smooth and liquid and, more importantly, does not sound the least bit shrill or harsh on peaks. In contrast, the Oppo does in fact sometimes make me cringe a bit on trumpet or tenor sax blasts especially. (There is GOOD bite - like you get with real instruments - and BAD bite.)

The Oppo does perhaps sound a bit more extended on both ends and a bit more dynamic, but in terms of cohesiveness and musicality, again, it is out of its league.

Unlike what some say I will not say that the DAC-41 "sounds like good vinyl" (rather, each has specific relative strengths & weaknesses). However, with a properly tweaked Mac Mini and appropriate USB cable it does sound extremely natural - as good as digital gets, I think, and at the overall cost we're talking about this is pretty remarkable.
Just wanted to add that I do think the Oppo 95 sound is representative of the Sabre "house" sound because I have heard several Sabre players/DACs and they do all have this house sound.
I've A/B'd the Tranquility SE with the DAC-41 and preferred the SE hands down. A smoother, more liquid, analog sound to my ears that is a cinch to live with. The 41 may be a bit more transparent-sounding, but I also found it to be more vulnerable to dryness in the midrange.

The biggest issue with the 41, I think, is that it's fairly lacking in dynamics for my taste - it lacks the toe-tapping factor, and the music is a little more prone to passing you by. Perhaps this is because of the DAC-41's strikingly petite and lightweight power supply? YMMV.
You are saying the T SE has a more substantial PS? The size of the case is the same...

Anyway, I do not find the 41 lacking in dynamics at all. The Zout is fairly high, so impedance mismatch is a possible issue.
