The Aries is pretty cheap you should get that. If you can afford the totaldac you probably could get both. Use the totaldac for local stored music, use Aries to stream and find music you like!!:D
They are AB i think 200/8 400/4 but they play like they have more power than that. If you watch the video's i believe he tells more about them in them. Their web site has more info too.
