A Couple Little Things I'm Wondering About

@millercarbon has the best system in the world. It is certified by..(drum roll)..@millercarbon himself. If you follow his instruction you will end up not liking your system because your ears, head shape, room size and construction are all different. @millercarbon's system sounds better than anything to HIM!

Cable lifters can help separate speaker cables and interconnects from power cords, which can help to reduce or eliminate noise in your system. My previous system had issues when power cords were too close to other cables, so cable lifters helped to keep cables apart and the noise to a minimum.

Other than that, the mere fact of lifting cables off the ground does not lead to audible differences in my experience.

However, this is why I still use them:

1. Cable lifters prevent my robot vacuum cleaner from running over my cables. I use heavy ceramic cable lifters which do not budge when the Roomba bumps into them.

2. RCA caps keep dust and other particles away from my unused jacks, and I feel they also might be helpful in preventing oxidation.

My cables are draped across my wall to wall carpet and my system sounds great to me. As far as plugging unused rca jacks, I don't see how it could make much if any detectable/audible difference. Waste of money if you ask me. I'd put the money towards a nice power chord or something else....

Once you get past plugging in all the gear and music comes out of the speakers, it a GAS.

cable lifters: snake oil

RCA shorting plugs: will protect against noise interference that may possibly occur at the unused rca terminals. Shorting them guarantees no signal, noise or otherwise will feed into your device.

@cakyol +1
In addition, some RCAs have a shorting mechanism built in which negates the need for a plug (as long as the designer connects up the third leg to ground). Ironically in my experience it's the most exotic and expensive ones that do without that mechanism.
