Precision Fidelity C7/A: To modify or leave as is?


Hello:

We recently invested in a Precision Fidelity C7/A and I was thinking of upgrading some of the OEM capacitors. The original designer -- Bruce Moore -- apparently built the preamp. to sound as good as could be in stock configuration without having to modify anything, i.e. evincing the philosophy that an intelligent design should be simple and sound excellent as is.

Has anyone upgraded their Precision Fidelity with caps. such as V-Cap teflons or Auricaps and come away with dramatic differences in sonics, either for the better or worse?

Thank you.

Thanks for responding: Yes, we plan on keeping the C7/A for the rest of our lives. At this stage, I simply do not know if $800.00 in V-Cap upgrades -- as excellent as they are supposed to be -- will be a move backward, contravening Mr. Moore's engineering philosophy on the C7/A that an impeccable, scientifically rigorous engineering concept should not need upgrading.
Thanks for the response Richard. This piece is in fact the "C7/A Revised," as I recall printed on the circuit board. I think it is a monument to fine, fine engineering bar none but the perhaps a handful of other preamps. Thank you.
Pardon my initial comment that the Precision Fidelity C7/A Revised is "a monument to fine engineering bar none but perhaps few other preamps." Rather, a more appropriate and balanced statement would be that it is "a monument to the finest of engineering bar none given phonocentric systems."
