Thank you all that replied.
Im still debating it in my mind. One thing I have noticed is the SQ is actually improved when DLNA through the Poly, using Poly with SD card as the server and the renderer. Better match probably, it should be, Chord with Chord. My simple stack is Shanling M2s to Mojo. The above beats it in SQ terms, others have noted this also.
I must say Im extremely tempted by the DX200 though. Also my old ears are not as discerning as once they were. Should i really be fussing over what are no doubt subtle differences between players at this level. Plus that well used phrase, " it's subjective". It would be an all in one unit, thats a big plus. Its a hard choice, Mojo does sound damn good with Poly though, i guess ill just have travel and listen.
