I auditioned the heck out of one of these against an Eastern Electric MiniMax, and an Audible Illusions 3A (used, of course) and I bought the Minimax, which I'm still in love with. Sweet and slam in one package - it's a great preamp! The AES sounded lush, but slower and mushier, to me. Now running Nuforce Ref 9s for power, and couldn't be happier! Check it out before you buy, if you can.
Cheers!
