I have had an Atma-sphere MP1 mk2 for 16 years. The only piece that’s lasted so long in my system. I’ve compared it to many other line stages and this is always the one I prefer musically to the others. I’m such a huge fan of the MP1. As far as the phono section in mine, it’s very good compared to others. For awhile now I’ve also been using an Aesthetix Rhea Sig. and really like this too. Mostly I enjoy the three inputs and programable inputs for load and gain. I run three tables with 3 arms. I won’t say one is better. They are different sounding and both have their own strengths. Both in the same league. I will say though that my preferences is all tubes all the way through. I prefer no step ups or even a FET in the input stage. Yes, noise can be an issue but worth it to me. The Thoress phono stage I heard in direct comparison to the Rhea Sig. It was quieter and a little more detailed, but no where near as musically exciting as the Rhea for my preferences.
