I've been struggling through some of the classic decisions that quite a few of us are faced with... Receivers vs. separates.... If so, which brands.. Models...... Prices... etc... Now I have narrowed down my budget and some options and have started to listen to a few of my choices. So, here is my question... What is the best process to listen to and compare equipment? How do you hook up the pieces being auditioned for the best review/comparison. Quite honestly, by the time I listen to "A", swap everything around and then compare to "B" it is difficult to compare critically. Am I really hearing differences or hearing what I expect to hear, or thought I heard? Is there any type of switching device that would let me hook speakers up to different sources and switch quickly for comparison? What has worked and what has not in your experience? Auditioning speakers seems like it would be much easier than source equipment. Thanks for the help!
