why just to have different step-ups and switched input?For tables like Garrard and Thorens I think you will use something like SPU anyway...
multiple TT, need 1 adjustable phono preamp
looking for a high end tube phono pre-preamp that can be used to run upto 4 turntables without unplugging. Currently I have an Artemis labs PL-1 which I am very satisfied with. At the moment my turntables consist of a Nottingham Spacedeck and a Garrard 301. I am searching for a Linn Sondek and a Thorens TD124. From there who knows. I am looking for something that can be adjusted on the fly; a button here and knob adjustment there from say MC to MM.
