I know what you mean about amps. It can be so difficult to select the right kinds. I wish I was in a house instead of an apartment so I could have some higher quality equipment. My neighbors would hate me if I had all the things I wanted!
I can relate to that, I run into the same problems with my neighbors, and I don't even think I'm very loud. I'm all for common courtesy, but some people really overreact in my opinion. A house would be great. An island would be better.
