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.

Are you planning on keeping it forever? If so mods may be for you. If not, I would rethink modding as it usually does not dramatically improve the resale value against the cost of the mods.

My experience is with a modded Cary pre-amp (cathode follower stage added along with upgraded caps, power supply, & standby switch) that generated only bluebook value on resale and a McCormack DNA-1 deluxe that was modded to the A level by Steve. Again resale value added was about 20% of the mod cost.

If resale does value does not matter to you and it is only about improved performance - mod away. A final note is that some mods may degrade the performance or balance of components chosen by the designer.
