I'd be glad to offer some insight. All of these posts are referencing his previous studio "the MTV house". They do not own that residence any longer.
I designed his current studio for David Frangioni (who is simply the best pro audio and residential integrator for this type client...anywhere). it was completed in Spring '08 and has last release Scream was recorded and mixed there (*some work was done at Kevin Churko's personal room).
The power is all Equi=Tech in new room and monitoring is all Genelec (active). I know the Bryston amp is still in his possession, but not used on daily basis.
I found Ozzy to be very together and on top of his craft.
