I did end up buying a RS250 about 10 days ago, and I can concur with thegm--it is a fantastic unit that is capable of SO much. I have several other DACs including a Naim, Auralic, and Holo Audio May and this little guy sounds great! I have it connected to two Dynaudio Focus XD powered speakers and with just the 3 boxes, you have a very complete system that covers all the bases. The Rose app can use a bit more work, but the touchscreen is worth its weight in gold--and looks just fantastic.
Really happy with this purchase!
