Some years ago, Chad Kassem of Acoustic Sounds sent me the Ron Sutherland designed AcousTech PH-1 for review. It was quiet and had good detail, terrific dynamics, and that all-important ability to grab and pull you into the music. At $1200 it was a steal. (I've not yet heard it, but the PH-1 was recently upgraded to a $1500 ''Premium Edition.'') Now, under his own banner, comes Sutherland's Ph.D., a $3000 battery powered phonostage that has forever changed the way I listen to records, and is certain to influence how I judge other phono preamps in the future.
