Atma-Sphere MP-1 Mk II vs. MIII


I would be very curious to know how those who have heard both in the phono stage would describe the differences and how much improvement one might expect for the money between the two. Also, how do they do with a SET amp with transformer?

How do they do with low output MCs (.3mv)?

With a MkII, a .3mv cartridge will be noisy without an SUT or a hybrid SS conversion as per my MkII. About .5mv is the lowest you would want on a MkII.
Check out Ralph Karsten's site at Atma-sphere.com. He has reviews available and papers explaining his components designs. I believe that his phono stages are designed to handle .3mv and above. He has a step up transformer available for lower output cartridges.
