I just bought a pair of SR-009s... my first electrostatic can. Will definitely be a huge improvement over my Grado 125s !
I am contemplating the driver, and am leaning towards the Stax 727 A/II, as it seems to be a better overall pair vs. the 007 tube amp.
My question is does anyone know where I can get a better power supply put into the 727? It seems like this can be a low cost way to improve the sound of the 727.
