Sharing this with my electrician. No DIY on this stuff for me. 

I ran 4 separate 20 amp runs with extra heavy wire into two hospital grade 20 amp double outlets. Looking back I wish I would have run three of them.

You might already have it, Any larger than 12  would have moved it to 25 or 30 amp, Still a single run, but man oh man, what are running, LOL
20s are 2400 watt continues right.. so 4 is real close to 10000 watt continues. I run 3 20 in the house sound room, and 4 15, in the shop, both stereo rich environments.  Both can and will exceed 145 db, with a very low THD...Glass is taped in the shop when I'm tinkerin' for sure.
Yup Yup..

Concrete crumblers at you place?

Upgrading the house wiring is the best you can do for your equipment. 1. separate phase (if you have 3 phase system)


You mean 3 phase elect, or 3 phases of something else? Lost me there.
Who has 3 phase elect. not many at all, ay. Single phase 220-240.

Voltage maintainers, and cleaners go a long way, NOT SURGE Protectors, useless, to maintain voltage..1000.00 wow, go a long
way with that, in materials. You can talk to a GOOD electrician for
about a thousand dollars... Really!!! No work though..LOL

In Europe you can have single phase or a 3-phase electrical system in your house (eg 1x230V at 35A or 3 taps of 230 V 25A). You can use 1 phase separate for your equipment and the other 2 for your all your other groups in your house. There will be no contamination from leds, dishwashers, microwaves, phone chargers etc..). If you have a oscilloscope you can check for the best phase with the least of noise from your neighbors. (I checked it at my listening hours)

If you want to do more, you can also put another earth rod in the ground for your audio system. There are some audio shops that provide this kind of service. I am an electrician myself and I worked at a cable company as a (test)engineer and I have some equipment at home (I am not on the level of a brilliant designer like Bruno Putzeys or Nelson Pass) but I understand the importance of low R,L,C values and a good foundation for your equipment. Tightening your screws and using contact enhancers is also a simple and good tweak to start with.
 

Try Pangea power cables at Audio Advisor. Very reasonable price. I use them with Spectral mono blocks and Spectral preamp. I am satisfied with the results.
