I've been messing around with the voltage supply to the 301 via my P10 regenerator and I'm pleased to say that the P10 set to 230V, 50hz, heavily regulated seems to generate further benefits. Bass has suddenly developed a more tuneful extension, piano decay and leading edge of notes seem a better defined. Brush work on drums seems a little crisper. Soundstage seems to have developed more cohesion. I understand that voltage values vary with values being quoted bewteen 190 to 230 making a big difference, I guess it's a case of suck it and see really. Oh dear, lots of experimentation needed! Next step is to decouple the motor. This IS something that I have to get round to doing in January. I've only been going to do it for the last year!!!!
