I agree with Gerrym5, and his comments about the Aesthetix. I've owned the Aesthetix IO (phono stage) for a good while, and just recently purchased the Callisto (line stage). the Aesthetix line stage is the best preamp I have ever heard, and I have owned or auditioned most of what is listed on this posting. Please give it a listen for yourself. The bass, dynamics, phase accuracy and contrast is undeniable, it truly makes the music a more believable experience.
