Flinx99,
I went to your "systems" picture and your rig looks really nice. If I had the real estate, I would like to try setting up one of my systems like you've done. On the desktop, the last system I had did it all, and the speakers were almost touching the back wall. Image width, depth, clarity etc. were excellent and no sub was needed. The front end in that system was extremely good. The Temple amps I brought in didn't hang around long. The picture makes the system look more cramped than it really was.
Ultralight,
Image width, depth, and focus can also be greatly affected by upline gear (amp, source, cabling, etc.). That said, moving the speakers out into the room will help image depth, and if you have a nice fast sub it seems like a no brainer to do so. The picture below looks about as "non audiophile" as you can get, but even without the sub running, the Super 3i's filled the 13' x 25' room no problem with a huge soundstage. My only criticism was the soundstage depth, though good, it could have been a little deeper, but traffic patterns kept the speakers closer to the wall for safety. For amplifiers: in my experience, nothing images like a good SET - they're downright spooky, and I feel if a person has one they can probably get away with having their speakers closer to the wall and still have that wonderful deep soundstage - having your cake and eating it too.
