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.

Bob... thanks for the heads up.  Did you get the resistors upgrades?  I have the v-caps on my preamp, it’s very nice.  
according to the manufacture they stated JJ for the preamp section (6sn7) and for the phono section they recommend the Shugan from China.  Anyone with accurate info.  let me know? 
Spoke with Ralph, he wants $2400 for both the preamp section and phono with caddock upgrades.  I think that just too steep for Caddock resistors!  
too many tubes on the phono section (10 tubes total ), no way it can handle .20v low mc, even when the manufacture claims that it has a total of 78db gain,  both chassis are the flimsiest designs, the power supply parts are from surplus ( not a single caps & resistors that are quality built in the power supply section). the silks screen letters would fade after many use.  That in all equal to very noisy preamp!
