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.

@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.
I have an MP-1 with all upgrades except Caddock resistors, which tubes are you running not NOS? Just out of curiosity?

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!  
It's not too steep when you consider those resistors are not your run of the mill Caddock. They are manufactured to Ralph's specifications for optimal performance in the preamplifier. Fiven what people pay for an MP-1 to begin with what's another $2400.
