I used the Rule of Thirds (29% Version) for speaker placement found on this site yesterday.

My room is 154" x 134." I am setup along the long wall.
Rule of Thirds (29% Version)"This is my favorite placement recommendation, and at least in my room isolated the sound from the room very well, as close to listening outside as I've gotten. I recommend starting with this and then backing up the speakers to the main wall as needed for adding a little bass reinforcement back into the sound and making room for other furniture if needed. Just watch out for the mid bass getting muddy as you back up the speakers."
Space Between Speakers 64.68" (5.39')Head to Main Wall 94.87" (7.9')
Speaker From Main Wall 38.86"
Speaker from Side Wall 44.66"
Previously my speakers were (measured from the center line of the speaker):
Speaker from Main wall 29"
Speaker from side wall 31"
I've never had my speakers placed this far into the room before and never had them this close. So far, I'm really liking the results. I'm getting a much flatter response (Vandy 2cs Sig II's). The soundstage is much more coherent and stable. The depth of the soundstage is crazy! Guitars are coming out of the front plane of the speakers. While vocals and drums sound like they are coming from 3 feet behind the speaks.
I know that good sound is very subjective. Are there any thoughts on any of the above?
I should mention that I'm using a Belles Aria int. amp. Source is a Node 2. Speaker cables are AQ Go-4. Gik bass panels behind speaks and diffusers at 1st reflection points.
Thanks!
