I´m looking for a linestage for my EAR 509´s monoblocks.
They are high gain as they only need 1.2v for full output, most sources these days have over 2v, you should look for a low gain preamp, suggest a Schiit Freya.
Which has 3 different output configurations tube, solid state, or passive, and it's remote control volume is about as good as you can get being 128 position relay switched controlled. And it's balanced or SE output with multiple inputs.
