Power Conditioners

said that isolation transformers(like the Torus toroidals) are a huge RF block to the power grid and does not allow noise to travel down the lines and out away from the components. But he uses one at the power into the office near the meter. But he wouldn't want one in his audio room.He has a Denali in his audio room....Between 1:00 and 1:24 is very interesting. I'm rethinking things now.

Vinylshadow, use your Gray on the line level equipment and plug the amps directly into an outlet. Get a whole house surge protector.

Thank you @mijostyn

I was thinking about that today...The question is, is a 12A choke not an issue for my Rowland Model 102 mono and 201 stereo amps used in surround(as far as higher amperage transient peaks), Classe processor and phono stage? Really I'm most concerned about my mono amp for my center speaker as it is a high voltage component and the center speaker is very active.... All else are low voltage. Except my Plasma TV which is the highest current draw of all of my components.

I do have 2 20A dedicated lines to use. One duplex would be for my model 12 and the other would be for the Gray 1200. But, I could plug the mono 102 above the Gray plug.....And the Gray would protect the Mono 102 since it is in the same circuit....


My 30A dedicated line duplex will be where one of my Model 12 monoblocks are plugged into. I believe my dealer in 2009 recommended 30A so I could also plug my powered sub into the same duplex and not adversely affect the current to the model 12. Do you agree with that? Plugging in both components will be ok current-wise to the model 12 and the model 12 will not be limited by the subs "noise"?

Do you happen to have a whole house surge suppressor recommendation?

Someone once recommended the Siemens Pro 140.https://www.amazon.com/Siemens-FS140-Whole-Protection-Device/dp/B013WINMK6
But another suggested a suppressor that I could switch off during critical listening and switch on all other times.
Thanks again. Much appreciated!

Vinylshadow, you could plug an arch welder into a 30 amp line! You have to remember that the impedance of all these devices as as much to do with current draw as anything. They are not low impedance loudspeakers. An amplifier can put 3 amps into the loudspeakers while only drawing 1/2 amp from the wall. It is converting voltage to current. 12 amps is more than enough to run all that you mention. You are probably only putting a watt or two into the surround speakers. People have this crazy tendency to over power their systems. The power supplies represent the choke point and most line level equipment and some power amplifiers are tightly regulated. Putting fatter wire in the wall is not going to make them perform better. Amplifiers that might overwhelm a 15 amp circuit are generally run 220 volt like the big Boulder. Also frequently forgotten is that it all goes back to the same panel so from a noise standpoint it is all being hooked together. Hopefully your Gray will isolate your more sensitive line level equipment. My own system is as quiet as a mouse. It is dead silent even with the volume cranked to the max and I use absolutely nothing. When I turn on my projector when the lamp fires up it will make the system stumble I put a transformer on it and it still stumbled. I put a power regenerator on it and it still stumbled so I sold it all, takes up too much space. If you have a source of noise in the house say like the refrigerator see if the Gray protects your system from it. 
Use Balanced interconnects with your amps if you can. Tie wrap your cables neatly into two bundles one power, one line level. If a power line has to cross a line level interconnect do it at 90 degrees for less induction. Nothing bothers me more than wire thrown around like spaghetti. 
The Siemans is a fine surge protector. I'm not sure which one I have in there. The tech installed it when the generator was installed. Many of them are sacrificial so it is a good idea to keep a spare around. I'm not sure about the Siemans. The manual will let you know. You'll have to turn off the mains when you install it so have plenty of battery lighting ready!

I forgot to mention that you have circuit breakers which are going to limit the amount of current you can draw from any one line and modern breakers are quite sensitive. You will know if you are overloading a line.
