Another useful link, thanks.
Don't know if you've seen this or its ilk, but it has been helpful for me in room set-up. http://noaudiophile.com/speakercalc/ You can adjust according to practicalities of you room of course, and some of you have other ways to find room nodes or nulls but it's a good quick n' dirty.
I'd like to see some tests or comments via Diff Maker with some of these wires you guys are using, since to be honest, it's hard to believe that some of you are using such connections on your otherwise very good rigs.
Shots fired? Well no, I'm not looking for a cable debate. My days with that are long over. I'd just like to see if a difference can be shown and if it may be audible.
