Highest Possible Sound Quality from iTunes

[Hifi_swlon]

One thing occurred to me earlier.  I have very little idea what an 'OpenHome control point is, or bubble upnp.  OK, I know that there are a bunch of control apps that can be used to control a Melco or similar, but I know very little about their functionality.  I have always assumed that they are all more or less the same as JRemote or iTunes remote.  I've also played with the Naim app for some time.  What I do not know if there is any broad range of functionality with these things, do some of them do anything interesting in terms of playlisting, sorting, searching or whatever? Or are they all much the same?
 
Ah then there is my own holy grail.....    Track ratings!  The only thing I know of that will deal with track ratings in an iPad app is Aurender's Conductor app.  Does anyone know of anything else?

I don't normally like bumping posts, it's poor forum etiquette I think.   However, I was really interested in seeing if anyone had an answer to the above, so I thought I would just this once.  I was a little worried this post had got lost behind NickB's worm can opening.  I'm now thinking maybe there is no answer to the above, or no positive answers re the track rating issue at least?

Maybe drop Womaz a note as I'm sure he'll have some Melco control Ap feedback. I imagine he's deeply blissed out with his new speakers though so might be a hard one to get hold of ......
