We have it up and running.
Some early impressions:
1. A no-brainer to get this one over the Roku, as the SB is MADE IN THE U.S.A. Worth the extra $$ just for that. It is very well made, and has a solid, quality feel to it.
2. It integrates quickly and seemlessly with Slimserver, and is as easy to use as a CD player once set up. We are running ours via Ethernet, so set up took all of 20 seconds. I can't speak to how the wireless setup would operate, but hardwired runs flawlessly.
3. Slimserver gives a lot of options, including streaming RSS feeds. Besides accessing all of our CDs in full wav (plenty of storage, no need for flac), we also have all of our old time radio and other MP3 collections accessible in a separate directory. The SB is facile with both, and it is fun to listen to old time radio shows through our tube system.
4. The sound, so far, is roughly comparable to a $300-$400 CD player. Very good. But I have and have heard better. It can get slightly thin and raspy in the upper registers. I'm hoping for some further improvements after 24 more hours of play.
5. The PS is definitely a shortcoming and may account for some of the sibilance. I will likely upgrade to a linear & regulated supply. Once connected to our big rig DAC setup, it should become less relevant anyway. I have no intention of doing any Boulder mods to it for that reason.
Overall, so far, this has been a very good purchase, and for most casual listeners will be more than enough player as-is. It is nice to have our entire CD library available this way. It is also nice to enjoy our computer-based media away from the computer, on a quality audio system, from the comfort of an easy chair.
