Hi: This could have gone into a few different categories (it really deals with the whole system, from CD to apmps and speakers), but I thought this would be the best place... I have been re-evaluating my speaker placement, and want to evaluate how the soundstage is. Obviously, some CD's might be engineered well, but not show a great soundtage... so what is a good CD to judge this with? Currently, I have been using Supertramp's Crime of the Century, but I would like to work more CD's into my mix for judgement and evaluation... Thanks!
