It's not a money thing. Get a whole house surge protector and be done with it. <$500 installed. Just keep in mind NOTHING will stop a lightning strike except physically unplugging your equipment.
Surge protectors--how many $ make sense?
My power went out during the LA fires. A power spike blew my preamp's fuse even though it was plugged into an ancient Monster transformer surge protector. So, I need to buy something to plug my gear into. The prices, however, range from a few hundred dollars to many thousands of dollars. Surge protectors have never been at the top of my list of equipment to buy, but I think it's time.
I have a fairly expensive system, about $75K, consisting of VPI Prime Signature turntable, ARC PH-7 phono preamp, McCormack CD (universal disc), Pass XP 30 preamp, Moon streamer, and Hovland Radia amp. New equipment mixed in with old, but all very good stuff. I've never compared surge protectors. So, how little can I spend on a surge protector without disrespecting my previous investment?
