What affects front to back depth in room/ system?


I've been moving speakers around for a while now trying to maximize their placement for a happy balance of soundstage width, focus of center image, vocal height, instrument placements, etc. I want to get the speaker placement settled before acoustically treating the room. The room is 15x20 with 8' ceilings. Speakers are setup along the 20' wall. I'm pretty happy with most aspects of the sound, but what I can't seem to figure out is how to improve the depth. Honestly, I'm not sure if what I'm after is attainable to begin with. Is it possible to have depth that reaches the listening position in a 2.2 channel sound system? The depth behind the speakers is great, just not much in front of them- unless it's one of those songs that has a part where it has that inverted phase trick. Then it washes over me. I want that all the time. Any feedback and advice is appreciated.

@veerossi Please consider trying 2 Swiss Digital Fuse Boxes, it replaces the skinny wire fuse with a solid copper rod which can pass tons more current and uses a microprocessor to sense current and protect your gear, you can change values and it can trip without breaking unlike a fancy fuse.

OP,

‘Thank you very much for the follow up comments. It is great to hear what it takes to get improvements. 
 

Please mention the brands and models of the cables and other equipment you used, this is the most valuable information. It is highly encouraged. This is why there is a place to show photos and to identify brand and model of all your equipment. Please share.

@klh007 Thank you for the recommendation. I'm happy where I'm at currently with the fuse situation, but will definitely keep it in mind if (when) I get upgraditis later on.

Preamp: I went from a Shunyata Delta NR (v1) to same cable but the most current version (v2). 

Mono block power cables x2: I went from Shunyata Venom V10 NR to Shunyata Delta NR (v1)

Fuse in pre-amp: stock to Synergistic Research Purple
