I was at Audioconnection a week ago and Johnny had an Aurender connected to the Codex (after running the Bluesound Node with the Codex).
In short, I was amazed at how much cleaner the sound (esp. Bass), was.
I contacted Aurender to find if I can hook up two of their units and play them synced (like Bluesound), they said there will be a new unit for sale soon, as well as software. Though it seems it will be limited to only 2 systems, according to the website.-Which is good enough for me.
I am still messing around with The Memory Player Mini, which I need to have Sam sort out.
In short, if things go well, I may have an interesting shoot out coming up.
