I have a heavily modded Rogue Audio Magnum 99 preamp with the built-in phono stage (modded as well). I'm running NOS tubes in there now too. Real happy with the sound of vinyl in my system. Warm and very involving. I use the included record clamp always. Tried it without for a while, prefer sound with. If I ever get enough cash my next TT will be a Basis, but for now I'm diggin' spinning plastic on the MMF-7.
