Atmasphere mp1 mk3.3 with phono


Looking for feedback on any members who did do the upgrades on this preamp.  Looking to improve the Phono stage and linestage, whether an upgrade on resistors would be the best for this preamp.

I think you should PM Audiogon member Pstores. He has a lot of firsthand info on Atma's.
Of course, calling Ralph(-Atmasphere) directly would provide the most accurate info.

When I had Ralph build my MP-1, I had them install V Caps (as per Pstores advice).

@zipost ,
My MP-1 doesn't have the Caddock resistors.
Though I have to say is holds it's own against an Ayre KX-R.
So, when moneys become available, I will upgrade the KX-R to Twenty status and the MP-1 to include the Caddock resistors-and any other upgrades Ralph might recommend.

@audition__audio ,
Interesting comment.
Can you provide an explanation  to explain the reason why Atma amps are improperly designed?
Are you a tube amp designer?
