Are Atma-Sphere MP-1 and VSE RTP-3D similar?


Can anyone explain difference in topology between these two preamps? Look similar except for the dual volume control and tube comliment. I'm thinking of purchasing one of them.

Thanks Tvad,

I have never seen the internals of the MP-1, so I was going by the fully differential balanced topology both preamps have. Do you know a site that shows the internal of the MP-1?

Yes, the Atma-Sphere has the advantage of being a US company with excellent support. I heard VSE support can be spotty, but the RTP-3D is a beautiful preamp.

Tvad, looks like you've owned or currently own several tube preamps including the ModWright and Supratek. Can you give a comparison between the MP-1 and the others?

Dracule1; why don't you give Ralph(Atmasphere)a call and talk with him on your concerns; he will answer you honestly and will not jam his gear down you throat to get a sale; this has been my direct experience.
