There are a lot of different versions of Aja, it being one of those classic audiophile albums. Someone correct me if I'm wrong, but I'm thinking the Hoffman version is a very specific MCA pressing (Hoffman also did some mastering for MCA, which I think was his work pre-DCC). Then there is the Cisco pressing, which was mastered by Kevin Grey @ Acoustech. When Grey's name is on it, you can pretty much assume it approaches the quality of a Hoffman release, since Hoffman & Grey are buddies and work together frequently.
