Do Audio Hobbyists Commonly Fail to Fully Utilize Their Systems?

Way back in the Stone Age, we used to go to customers homes to test set up. Complete with DB meters and test records! We'd discover the funniest things! We are now on our own with sometimes increasingly complex systems. What possibly could go wrong? "Weakest Link Hotline" how may we help you today?

(To Artemus_5) Did I enjoy my system for the past year even with those filters fighting each other? Yes but....I was looking for an upgrade (always) feeling there was a "hole" in the sound somehow. (Lack of cohesion, maybe) Its hard to describe when you sense something is off. I realize that may be the case no matter the condition of the music. However, I do listen quite a lot. And, after a while one can perceive various nuances that if engaged repeatedly and on a daily basis begin to stand out. I guess what I'm getting at is this...if I describe every detail of my system down to the room acoustical factors, cables, components, the potential synchrony between these items, etc...could the perceptive amongst us identify potential "weak links" in this collection? Yes, it could be done. In fact. I hear samples of this threading its way through many posts here on Audiogon. A journey? Yes, indeed but I'm actually trying to go somewhere! Maybe I'm searching for a musical mirage just over that sand dune ahead.

My son walked in our living room and said (in front of his mother), "Dad! You've designed this room entirely around the stereo!" "Come on (I feigned denial) that's ridiculous!" Wink Wink....Since I live in a 30 ft yurt, the walls are fabric. 15 ft ceiling at peak. My listening chair is positioned in the middle of the circle house. My speakers are 12 ft apart, and 14 ft from me. Above the level of the Klipsch Lascalas sits a large curved screen at the top of the wall between the speakers and above my components. Turntable on a suspension platform to the left side, sub on the isoacoustics sub stand to the right. Imaging is incredible if recording is done well.I've built angled walls 7 ft tall narrowing toward my sweet spot leaving a straight wall behind my chair 3 ft and extending to my right and left 6 ft. To the right and left of both speakers there's an open walkway of 5 ft. Sorry need pictures. I'll work on it.
