The OP got an interesting thread / dialogue going on with his initial post, an often debated topic of power, how big an impact it has in performance and the best solutions.
OP - your direction really depends on what you are looking to accomplish beyond Surge Protection. Are you looking to clean up “dirty” power? Are you looking to isolate each plug, eliminating any electrical interference prior to the plug? Are you looking to provide more stable power that can deliver reserves of power if a demanding unit (amp) requires more power at times to reach peak performance? If you go with a Power Filter only, it can limit power delivered to a power hungry amp which can dampen dynamics, overall performance.
Deadhead mentioned Furman - if you wanted to jump into adding a power solution to your system Furman is a great product, value. They are one if not the most trusted and used name in Professional Broadcasting Studios. They are the brand the pros go to. It’s not that some of the Audiophile brands aren’t as good but if you want a unit trusted in the field by those who are trusting their livelihood, great option. I’m not affiliated with Furman, I do own the Elite 20 amp unit. It’s a great filer but it’s not an isolated or power regenerator. It’s not ideal for someone with a power hungry amp. It is a better filter option than other units performing the same functions but not the right tool. It also isn’t an isolator, if you are looking to isolate power for each unit, this unit doesn’t do that, either.
You don’t need to break the bank to find unites that can filter, isolate and are not power limiting. Power regenerations which is another level of providing max power to a hungry unit can get pricey. There are some great boutique companies that build units using higher grade parts than most, the engineering behind design on these units isn’t a secret, so if they know how to design, build the unites you’ll get great performance with better parts for a much better price. I’d buy something that filters, isolates and isn’t limiting on power. That removes the dirty power, isolated the units you are plugging in meaning any interference or noise isn’t coming from your power grid or other appliances, items plugged in and the units won’t be bottlenecked on available power. This can make a marked improvement in performance depending on your gear, requires a well engineered product with quality parts. Doesn’t require any fancy marketing, audiophile terms or some newly discovered technology. I’m in the North East and Pine Tree Audio is a great option but there are plenty of smaller manufactures with the passion, know how that offer products with great performance and value relative to the more well known brands.
