Well, having looked as well as I can around the Roon Partner offerings, I can't find anything to compete with the functionality and sound quality of this (outside a Meridian DSP system) near its price-point. Clearly, there are superior products with superior functionality and connectivity (much of which I don't need), but there's a price to be paid for that. I may just have to buy another.
