Bearing in mind most on here have forgotten more than I’ll ever know about high end audio, I agree with the above said.
A. I have what I consider an old mid-level system. Adjusted for inflation, everything would run you about 17 grand nowadays. With such a system I’m not much of a believer in a power conditioner. BUT... I am a FIRM believer in using a battery backup/surge protector. APC Back-UPS to be precise. The exact model you want will depend on how much power everything draws. This protects against power surges, power drops and power outages. All of that prolongs the life of just about anything plugged into it. Examples: My 22 year old cathode ray TV still works like brand new. It gets watched every weekend. All of my 33 year old stereo equipment still all works too. Yes, a few capacitors have been replaced but not much you can do to avoid that.
B. Speakers. Yeah, get the best you can afford. That and a clean amp/preamp will do you the most good.
