What would the result of this drying out of fluid be on the performance? I'm still leaning towards using "as is" for two reasons. Restoring is a hassle for me (I would likely damage it and not sure where to look for tech people) and the NAD is way better than the entry level I upgraded from. Sonic improvements no matter how subtle is what matters to me most so the NAD is still very satisfying compared to my old amp. However I do borderline obsess about optimal performance from my system. If I decide I really want the work done, I guess I'll learn to do it myself. In the event of a screw up, at least I would have learned a few things about one of my hobbies (and there are much more expensive amps out there waiting to be screwed up) The engineering and how an amp's components "communicate" with each other and perform their functions is a mystery to be uncovered.
It really depends on the circuit design, how bad the cap has gotten, where in the circuit it is, etc. I've had amps with a bunch of caps at half value that didn't sound much different (if at all) with all new ones in place but an amp with one bad filter cap that's throwing 60 cycle hum and you're definitely going to know.
