Maybe .. becourse you have not asked for it
Integra is very young in Europe and we are very found of 2 channel
and we allways search for solotions that makes us happy.
Audyssey is very good, but we do not use it for 2 channel
But maybe it will be moore common with XT32 than it was before.
We want to come so close you can get to Pure audio, but with Integra
the closest way is to use Multichannel input ..
But with Sonos your choise is digital in to Integra if you do not...
