Ok, so I spent some time on this rather miseaprable, wet afternoon persuading Audirvana Plus to work with AIR. My setup is:
iMac, OSX 10.6.8, A+ 1.5.12, AIR 2.1.2
In order to get A+ to work with AIR I had to disable the following preferences in A+
Exclusive Access Mode, Direct Mode and Integer Mode. I selected Use Max I/O buffer size.
Maybe it was just relief after getting the s/w to work but A+ did at first seem a bit brighter and more airy than vanilla iTunes though after listening to a few more tracks I'm not so sure. I have a couple of weeks free trial and plenty of time to compare the two and will report back later.
I still don't understand how A+ could improve on iTunes through AIR particularly as some of the supposed best features of A+ have to be disabled to get it to work???
EDIT: I would add that the output from A+ seems to be a couple of db higher than iTunes which may account for some perceived differences.
