Arafiq, I am in total agreement about the lack of info. I have been scouring the manufacturer's websites to find streaming products and I am finding very few that look like attractive options at any price. It seems this section of the industry is still quite undeveloped.
My my options seem to be to buy a $500 streaming device (bluesound node or auralic mini) to replace my mac mini and connect to the PS Audio PWD via USB, but this makes me rely on the USB which reduces the quality of playback of the PWD by not using its onboard player in the bridge, and it also means I am investing in an underdeveloped user interface in either of those streaming products. Basically, I am not super excited about either.
My other option is to sell the mac mini and the PWD and purchase one of three stand alone DAC streamers: the Sony hap-z1es, the Cambridge 851N, or the Marantz na11s1 (the Marantz being a bit north of my budget). The issues here are, I may be taking a step back in sound quality from the PWD, and the question of user interface is still there - how mature are these other options?
i think I am going to give the old college try on the PWD bridge, and see if I can get a different software other than JRiver to work. If I still find it too cumbersome, perhaps I'll audition the Cambridge unit, as it looks very flexible. Has anyone compared to Cambridge 851N to a higher end ($2500 a $5000 price range) stand alone DAC?
