I just received my SMS-100 and I love it. It just works. I have been a longtime LMS user and really love my Squeezebox Touches. However, I have been looking for a replacement that handles DSD and seeing how Jesus has a Mac version of LMS that does DSD(I use a Mac as my server), the SMS-100 seemed a natural fit.
I have only had it a couple of days and it is all I hoped it would be. I use it along with a Teac UD-501 DAC and the iPeng 7 control app. For you Squeezebox users it is highly recommended.
