It can be a plus but it depends on who does the work. ARC still services everything they have ever made and any piece of their used gear you send to them will come back sounding as good as it ever did unless they tell you ahead of time that it can't. VPI, Well Tempered and MIT pretty much the same in my experience. Likewise Vandersteen and Thiel, although it's not always worth repairing speakers.
For an aftermarket repair shop, by far the best I've encountered for electronics is Stereo Surgeons in Hartford, CT.
Then there are vintage electronics: I happen to have a Hickock 539C Tube Tester that was repaired and calibrated by Chris Haedt. Documenting his having worked on it would greatly increase its sale value today.
