What about your transformer off main line? Do you share it? is it old? Are you in a urban area? What about the line from transformer is it lower gauge old or new? I would suggest a separate service for audio room all outlets run direct to breaker at min use hospital grade outlets. Many cant not address the transformer but when I has able to get one just for my home my AC cleaned up so much I have no need for a re-generator or much filtration.
Building a house with dedicated stereo room-advice
Building anew house with a dedicated stereo room. The room will be built using ASC's IsoRoom system. It will also have dedicated lines and I will purchase high end plug in receptacles (advice here?). Anything else I should be sure to include? Please advise, particularly with the electrical distribution.
