use an extra deep outlet box .
This is definitely something you will never regret later!
More questions about dedicated lines

@ orthomead Just curious, Where is the main electrical panel located? Example, garage, laundry room, mechanical room, on the outside of the house. Manufacturer of panel? Electrical panel main breaker size? Where is the sub panel located? How big is the sub panel, ampere rating? What is the handle ampere rating of the 2 pole breaker in the main electrical panel that feeds the sub panel? (Number is on the breaker handle) How many empty spaces are left in the sub panel? Number of empty spaces on each side? Panel manufacture? Any idea how big, horse power rating, the pool pump motor is? Voltage rating? 120V or 240V? Is the motor controlled by a VFD (Variable Frequency Drive) controller? |
I think you should use a separate 20 amp line to each amplifier. Use three wire Romex just in case you ever want to run a 220 volt amp. Then you need one other 20 amp line to a power conditioner/surge protector. I use a Furman 2400 IT which I can not recommend highly enough. All my other equipment is plugged into it. All grounds should go back to the panel. Ideally all signal connections should be balanced including your turntable. Any standard outlets will do. Spend the money on your power conditioner. Audiophile outlets are a bad joke like cable elevators. |
Ouch. Oh well. There are those who "know" because they "think" and there are those who know because they have done- AND HEARD. I find solace in thinking those who throw away vast sums on bad advice have such vast sums they won’t even notice. One thing I cannot quite figure out though. If the whole point is to get better sound, why take advice from people who say right up front they can’t hear? Especially when at the same time they are admitting they don’t know, because they haven’t done? Oh well. Your money. Throw a match, watch it burn for all I care. |
Wow ..... that is some serious sour grapes. I will repeat what Almarg posted, and point out the obvious inverse/square law, i.e. RF sources nearby will have far more impact than distant ones: Regarding the possibility of using the large commercial regenerator that was suggested by the electrician, if I understand correctly this sounds as if it may be something like a very powerful UPS (uninterruptable power supply). If so, what I would ask about is the possibility that the circuitry in it might generate significant RFI (radio frequency interference). I can tell you that if I bring a portable battery powered radio within a foot or so of the relatively small UPSs I use for my computer systems (which are the type that generates true sine waves, not stepped approximations of sine waves as is done by many inexpensive UPS devices that are presumably more noisy) the high frequency noise radiated by their circuitry is picked up very strongly in the AM band. |
