I know battery back up is not a replacement for surge protection, but does anyone use UPS for their low power equipment, such as dac and streamer, or CD/DVD player? I use one for my router and modem in a different room have had improved reliability, likely to to less brownouts which are more common where I am at. The unit says surge suppression, but not sure if it works well for that. I don’t think I have many surges.
This is what I use for surge suppression (not UPS). No issues, but like I said, not a lot of surges that I know if in my area.
