Full HD network media players

Hi All,
I’ve spent the last few weeks looking for a reasonable Network Media player which will support full 1080p ( most do ) and specifically DTS -MA & True HD audio even if only passthrough via HDMI ( Receiver can decode no problems)
Reason I’m after this support is I’ve started to back up my Blu-ray collection to NAS as I’ve already done with my DVD collection.
Currently I have 2 media players ( both Beyonwiz www.beyonwiz.com.au products which perform very well with fantastic support from Beyonwiz) but can’t handle HD audio bitstream
I had purchased a Media PC but took it back 24 hours later as there was no HD audio support as guaranteed by the distributor

Any suggestions ???
