need advice for sound improvement

Happy New Year everyone!
I would appreciate your help to improve the sound I can get in my listening room from the following system:
- Marantz SA14s1 SE (Ken Ishiwata)
- McIntosh C2200
- McIntosh MC2102
- PMC OB1i
- Wireworld Equinox 5 balanced interconnects
- Black Rhodiun Salsa speaker cables 10 m runs
My room measures L470 x l330 x h240 cm and has one door behind the speakers and one door on the right wall (as I face the speakers). The speakers are places facing the short wall.
I encounter two issues:
1. I cannot find the proper bass sound. Or it is boomy, or it hangs over or it is very thin (good definition but lacks the oomph)
2. The vocals are placed at 1 o'clock (imagine the speakers sitting at 3 and 9 o'clock)

What can I do to improve on the above?

The speaker cables should indeed not be a problem, unless the cables would be very thin. See here for some data: http://www.audioholics.com/audio-video-cables/speaker-cable-gauge In general, if a speaker cable has to be long, the solution is simple: use a thicker gauge. In your case I doubt this will make any difference.
The most obvious explanation is still room modes, perhaps aggravated by the transmission line design of the speakers.

I built a modified QRD 13 that's 20" deep, with the verticals 3.5" wide. It broadened my soundstage and helped my bass. I placed it flush with my front wall. Hemholtz absorbers may work, or Dennis Foley has plans for an absorber I'm going to try. Multiple subs will also help. I have about 20 wall panels made of 1" compressed fiberglass board covered with speaker cloth that really helped me.

Many thanks again to each contributor.
I received a lot of ideas and I will do my best to experiment most of them.
I am in the process of playing with the speaker placement and also I have ordered Jim Smith's book. Till it comes, I am watching the educational videos from the GIK Acoustics web site.
Will keep you informed once I have more progress.
