phono Symphonic Line integrated amp

Hello all,

I own a VPI Scout with a Lyra Dorian cart. This goes directly into my integrated Symphonic Line La Musica amp. This amp has a inbuild MC only phono stage. However does anyone know how good this stage is. To me this combo sounds good enough for now. But I was wondering how much I would need to invest to get a better sound of my turntable. The only thing I know is the phono stage is better the the Clearaudio Basic that I used to have. But if I were to upgrade at what level would I need to look. Any here have experience with Symphonic Line amps and the inbuild phono stage?
