Speaker placement and soundstage

@danmar123 You're welcome but I learned about it right here on Audiogon. The method makes a nice difference for sure and it's free! Once placement has been done then you do the room treatment.  It then gets even better. 

I've been working with GIK for the last week to finalize my room treatments, but I'm not going to extend myself until after the summer. My bass bins are 9.5' on center with a brick fireplace in between, on a 13' wide room. We came up with 7 panels just in the front end & 2 in the rear wall.

My room is really tricky. Even a door in the corner of the back wall. I ordered a total of 13 panels and bass traps. Some panels are for the ceiling.  Not all have arrived yet. They are produced on demand so be prepared for it to take a couple months for everything to arrive. 

Like others have pointed out speaker placement is never one-size-fits-all, and upgrading your gear can completely shift the dynamics. I loved my Klipsch LaScala AL5 speakers, but upgrading my Accuphase DC-37 DAC to the reference DC-1000 suddenly highlighted a slight hollowness and glare in the presentation. By reducing the toe-in and pulling the speakers 4 inches further out from the front wall, the sound was completely transformed. Musuc has become incredibly engaging, yielding punchier bass, stronger note authority, a massive 3D soundstage, and much better coherence.

After experimenting with moving my speakers farther apart and less toe in, I was surprised how much better I liked the sound stage and the way the speakers "disappeared" during playback.
