Fremer was using the $18,000
AC Nexus Advanced Power Distribution & Ground Enhancement System by SMc Audio, and for an additional $8K they will throw in a four-foot EnKlein David power cord.
The SMc Power Distribution device uses a 15A input. My Isoclean 60A3 is in the same boat as there are indeed three 20A outlets on the device but it only accepts a 15A style power cord. I use it to power everything except my monoblocks. I doubt a single 15A or 20A line would be enough for my whole system when SMc Audio themselves suggested providing big power to my new SMc monoblocks, each of which have a 10A fuse.
All of this is moot if @gdnrbob is happy with his current power situation. However, if not, depending on the makeup and location of his system(s) running a single big line (50-60A?) to a sub-panel located near the system may be a better solution than running multiple lines from the main panel to the room, especially if the room is a long distance from the main panel. Power lines from the panel will all be grounded the same and can then be used solely for the audio system(s).
Fremer can do what he wants. I have never had a problem using a lot of clean power grounded from the same side of the panel, front-end stuff through a filter and amps from the wall. YMMV
