I have wondered about this. It's always seemed to me that some of the credit titles (can't think of one offhand) in AMG are different to those used in Sooloos.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
