Just thought I'd share this about the wiring and electricity in my house, and how it makes a big difference in sound at least in my case.\n\nI live in a 130 year old 3 floor apartment building, with each floor a different apartment. I have a window AC unit that was blowing my circuit everyday, if I had the TV and lights on. I got an electrician to come out yesterday. It turns out my window AC, home theatre, TV, living room lights, kitchen lights, microwave, and 2 other conduits that he thought were going to my apartment but were actually going to the 2nd or 3rd floor apartments were all on one 15Amp circuit! Whoever wired up my building originally made a crazy mess and put way too much on 1 circuit. So the electrician ran some new wiring and conduit, and split up that one circuit into 4 different breakers now. He also saw that my home theatre and AC unit had 20 amp wiring already, so he put a new 20 amp breaker for that room.\n\nNow when I listen to music, I was shocked everything sounded so much better and clearer. The bass used to be boomy and indistinct, now it's a lot more focused, not boomy and I can hear every bass note distinctly like they are playing next to me. Also the midrange and treble is so much more focused and detailed. I can hear all kinds of tiny details I never could hear before. I was listening to Bill Evans Live at the Village Vanguard. It's recorded in a smoky Manhattan jazz club, and now I can hear the conversations in the club in the background and the glasses being put down at the tables and bar. I felt like I was right there in the smoky jazz club, and could hear the people talking at the table next to me!\n\nI didn't change anything with my sound system, I couldn't believe just the building power would make such a difference. By the way, I always turn off my AC unit when listening to music, so it was never even running before. I feel bad but I'm even using lamp cord for my 4ohm Phase Tech tower speakers, I really need to get some better 10 gauge cable now, and I bet that will make a good improvement as well!
