at least on my PC based server. Jury is still out on the MacMini as the main system has been taken over by Christmas decorations!

On my office system(s) I have been using either my dedicated mini-ITX that I built for audio or or my Dell XPS running foobar with the AQvox ASIO driver. The AQvox driver really helped the PC based solution. That is until Kevin Burke of Mach2 Music recommended that I try Silverjuke. The difference is really big in a good way.
http://www.silverjuke.net/en/It is 25 Euros ($38.22 when I bought it) and there is a trial period.
I pretty much like everything about it. The interface is very good. It is skinnable, does every format that you can swing a dead duck at, does sample rate conversion, has a good ripper: ie, just about everything one could ask from a player.
If you've tried it, I would like to see your comments, if you haven't I would encourage you to do so.
Of course, YMMV, but I don't think I'm daft. Well, maybe I'm wrong on that, but I don't think (or hear) so on this one.
