Hello,
A great topic often overlooked by folks trying to build their music room or HT room. I consider speaker postioning as one of the key framework items in this process w/o which it is amost impossible to get the best performance out of your speakers and electronics regardless of their cost. To me this audio framework covers following list of items, not in any particular order.
1. Speaker Postioning
2. Electrical framework, includes dedicated circuits, quality AC distribution units with star grounding, AC recepticals, etc
3. Vibration Control platforms
4. Room Acoustics & Room Analyzing softwares like REW
5. Cable management. Separating AC cables from other cables and makung sure that none of the cables have a long parallel run
Unlike other components none of these (excludes AC components) have a plug & play feature. I had to spend a great deal of time on each item to integrate it to my listening room. And this was not easy. But as I mentioned previously w/o this effort any money spent on speakers and electronics would lead to less than optimal performance and frustration.
Thanks.
