Like, completely gutting the entire place... building an inside wall that's not parellal so you don't get reflections... building up the floor with multiple layers of rock, rubber etc.... isolating the inside wall from the outside wall and floating it free so that it doesn't contact the outside wall in any way...
major rewiring to get rid of that constant a/c hum buzz I keep getting...
isolating the computer and sound equipment... monster cable.
I'm totally freaked with how much research is required. One of the main problems is the place I own is semi-detached... actually, all the units are attached along the coast. And most of the neighbors are exremely elderly.
