Also seriously consider Bill Thalmann of Music Technology in Virginia. Former Technical Director at Conrad Johnson. HIGHLY recommended! The problem I had with Conrad Johnson is that their upgrade package on my preamp 5 years back was limited to their proprietary teflon caps and didn’t involve other upgrades that can provide greater realization of what is possible. Bill can explain what can be done and give you broader options.
To expand on Eric’s comments, Bill uses V-cap CUTF, great caps.
