Momentary power interruption caused damage ?
My system consists of a Vecteur L4.2 ss CDP, an Audiomat Prelude 30 wpc tube int. amp and B&W N803 speakers.
Two weeks ago, I had a momentary power interruption event(power cycled off and then on within a second) during my listening session. I don't use surge protectors, I am in the process of evaluating conditioners and most of them seem to constrain dynamics and have decided to install a whole house tvss at the breaker panel. I take all the precautions - equipment unplugged at the end of a session and I don't do listening sessions during thunderstorms and such. Power is usually good in my area - no brownouts, sags or dips etc.
Anyways, after the interruption, I have noticed more than normal sibilance out of my speakers. I believe that the amp is probably protected by its power supply and the cdp has a fuse that may have saved them in the event of a surge. Also my amp turns down its volume when powered on. In any case this was a momentary interruption and there may have not been a surge.
Could I have damaged the tweeters in my speakers ? Is there a problem with a capacitor ringing in the amp or cdp ? I did inspect the tube amp and found no visible damage - blackening of caps etc. In any case, the system is still performing reasonably well, but I can easily sense that there is that added sibilance - which is highly irritating to say the least and making me want to shut off the system.
I am planning on swapping components to see which may be creating the problem, and potentially servicing each of the components - the beginning of a major pain. But if any of you has had this unfortunate experience or is knowledgeable in this area, could you educate me on what may be affected in my system ?
