Next, you would want your listening position to be in the middle between the two speakers.
I see that in your setup, that will be hard to do because of the opening by the chair.
First suggestion, if you are going to keep the speakers you have OR get different bookshelf speakers, then get two stands, about 22" to 32" tall, and put the speakers on them, one on each side of the piece of furniture that holds your electronics. If you can't sit in between the two speakers, rotate the outer one so that each is pointing mostly toward your seating position. But you will still have a little problem of one speaker being farther away than the other from where you sit. Modern receivers can compensate for this, but yours can't. It may or may not be a big deal to you.
Second suggestion, I see that you have your receiver kinda crammed into that furniture, with the receiver on the bottom and other components directly above it. It has no breathing room. Receivers (or amps) generally generate a lot more heat than any other electronics components and need ventilations room, on the top and sides - but especially so with the top. The placement as it is now means the receiver is probably getting pretty hot. Over time, that can cause failures. That makes me worry even more about components going bad inside it, given its age.
If you can, move it to where the preamp is, so it has room to breath, and put the preamp down below with the dvd player and the equalizer.
