What About Loom Theory?

Assuming you are referring to use of cables and power cords from a single manufacturer, as Onhwy61 inferred, see this thread. The thread initially focused just on power cords, but eventually broadened in scope to address all cables.

As is usual in audio, there was no consensus.

"Loon Theory," yes. Self explanatory...

I'm not sure it's "loom theory" as much as "loom speculation" which hypothesizes that one can/will achieve better sound if all cables are from the same manufacturer.
I'm sure you can get great sound that way but I know from experience that it can also be achieved by mixing and matching brands. So where does that leave the "loom theory"? Pretty meaningless IMO. Probably not worth any more time than already expended here.

Ok, well so far it seems like "loom theory" is pretty much synonymous with "system synergy": a synergy achieved by matching loudspeaker cables and interconnects, or, power cables, or all three together perhaps.

Thanks for the info. If anyone else has anything to add, please do.

Nordost is one company that promotes this philosophy in regards to selecting cables for a system. You can see their explanation for it in their document entitled Foundation Theory, under the section heading "Interconnects and Speaker Cables". They say that it applies to power cables as well, and they also state that a more expensive cable is not always better in specific applications.
