Okay there was this other little DAC at the shoot out called the Music Streamer II:
http://www.musicdirect.com/product/87045Steve brought this over and I was interested in hearing it, but there wasn't a lot of enthusiasm to really compare it to the big dogs. I didn't think it would really be a good comparison to anything else, and I was wrong. That was a mistake in my thinking for sure. It was comparable to some of the big dogs.
This thing runs off of the power that it gets from the PC. It does not have it's own (noisy) switching power supply. That can really be a plus.
Keep in mind that it had an unbelievable front ahead of it and the USB cable cost nearly twice as much as it does.
Plugged into a standard computer and using a $5.00 USB cable, it might have sounded like poop.
However, in this system, it was very surprising.
I think it was very comparable to the Ayre, PS Audio, or Onix. Yep, I said it. However, once any of those were plugged into the balance power supply and Uber buss then they would pull away and level this little thing behind a little. I also think that even plugged into the wall, the PS Audio DAC (as a stand alone DAC) and the Tranquility were on a different level.
From a quality perspective though it was good. Some people like Chris will favor the Ayre, because it is a smoother sound. And in the right system the Ayre may really be a better performer. It is a matter or taste.
My thoughts were that it had good bottom end. And that was a surprise since it was getting power from the Mac Mini and feeding a tube buffer (Dodd Audio) pre-amp with no gain stage. Having drive was not an issue though. Highs were extended well too. The sound stage and imaging was also extremely good. It still had a bit if that digital sound though. It was not smooth or refined. It had detail but was on the sharp side.
All in all this was an extreme over achiever.
