Cardas Nautilus is a good quality one.. I recently compared the Nautilus with my old but high quality power conditioner… within a minute put back the power conditioner. This is not a knock against the power strip. Sometimes power conditioning is not required… but usually it is. Has been in the three homes I have had,
I have two direct lines. One for the amp and one for the rest of the system. 10 gauge for amp on mirrored breaker (second 110v leg). Typically one plugs the amp directly into it’s own outlet and the remaining equipment in to the power strip or conditioner.
