Not sure what you're asking here, since you seem to have answered your own question. But if you are looking for another tube preamp with a great phono stage, stroll over to the nearby VAC preamp thread and look there. But whether it competes with what you have can only be answered by you, by audition.
Best preamp with built in phono stage?
I have and love my Atma-Sphere MP-1 preamp with its excellent built in phono stage. A two box tube unit. I don’t have rack space for a separate phono stage and don’t want another IC. Not to mention the cost of a high end line stage and high end phono stage. The MP-1 was specifically designed to play vinyl. 8 of its 18 tubes are dedicated to the phono. In many ways, it seems to not have competition. Surely, very pricy line stage and phono stage can surpass it but I don’t know another high end pre with built in phono that compares.
