The long / Narrow room - system configuration


I have always and still do have a longish (23.5 feet) and narrow (12.4 feet) listening room. I have always put my speakers on the short wall with my monoblocks and run a 25 foot long (rca) interconnect in between my amps and my other components which sit away on the long wall down by where I sit to listen. Have most chosen to give up on this type of configuration in order to go with much shorter IC. I would have to move all my FE components which sit on a fairly massive Rix Rax Hoodoo and move them all ( including turntable)
in between my speakers. In most of all your experiences, would what I gain in shortening that 25 foot cable be worth it if I then negatively affect my soundstage with a big ol rack full of my FE components between my speakers.

I find that the room position effects are much more important than the cable effects. As for which position is best, I prefer to sit facing a short wall, with the speakers well out from that wall. So, my advice is keep your system as it is. Whatever improvement you will get from shorter ICs will be outweighed by the harm from the new speaker position. Some damping at the points of first reflection on the side walls, and floor and ceiling, can help too.
I have a similar setup; my room is 21 feet by 13 feet and I have the speakers on the short wall about 6 feet out into the room. I also run long interconnects from the preamp, which sits near my listening chair, to the power amp, which sits in between the speakers. This has been working quite well for me.
If I had a room like FJN04's, you could not machine gun the smile off of my face. My tiny dedicated listening room is 10x14 (with a 10 foot high cathedral ceiling). My room blows. Speakers go on the long wall, about 6.5 to 7 feet apart. They are pulled out from the rear wall about 2 feet. This puts my ears just a few inches shy of 8 feet from the fronts of my drivers....and that is with my back against the wall. Short of mini-monitors easily doing their thing in there, it has been a long road getting a variety of somewhat larger speakers to sound good in such a small room. Giving the speakers 3 to 4 feet on either side has always yielded better results...for me.

I have tried putting speakers on the short wall, but without exception, I find that speakers need more breathing room on the sidewalls than they do from the rear wall. Sure, sitting further away gives more time for the drivers to more wholly integrate (nearfield listening tends to slightly accentuate the higher frequencies, depending on the speaker's design) but flubby bass echo/boom from close sidewalls is the worst thing that can ever happen to your hi-fi experience.

I would take sidewall breathing room (and nearfield listening) any day of the week over the bass boom that has plagued my setup whenever speakers were placed on the 10 foot shortwall.

FJN04, what exactly is stopping you from at least experimenting with a new layout? Instead of moving every last front-end component and the big Hoodoo, why dont you just throw your linestage down there between your monoblocks (with a shorter interconnect), hook up a CD player to it (also on the floor), and see what happens. I gurantee that with the Hoodoo and a turntable on top of it, you will hear a diminished soundstage between the speakers, so dont go to all the trouble of moving those things just yet. Start by simply moving the pre-amp and the CD player over there first. At the very least, you'll get to hear what a front end component sounds like without a 25 foot long interconnect running between the amps and pre-amp, and you'll also get to hear your speakers from a completely different perspective.

Hopefully, you'll hear no difference, and just keep your present setup. As described, it sounds very convenient.

Good luck,
Jake
My room is slightly shorter than yours, 20' but the exact same width. I have a flat 8.5ft ceiling. My equipment is set-up in the manner you're considering. I keep my equipment on two low racks between the speakers. But for the distance from the side walls and rear walls mentioned by Nsgarch, I agree with everything else he said about speaker placement, seating position and long narrow rooms. On the distance from the side and rear walls I think you need to experiment. It depends on your room and speakers. I have my speakers about two feet from the side walls (measured to the center of the drivers) and 39" off the back wall (measured to the front of the drivers) with very little toe-in. My seating position is 9' from the front of the speakers. All very close to what Nsgarch suggests. I have found this room set up gives the best soundstage and frequency response. I also agree with Nsgarch that the way you have your room set up now is probably the best. If you were running balanced IC's for that length into balanced equipment, I'm not sure you would lose more than you would gain from the change you are considering. Depending on how much noise if any your 25' RCA IC is picking up or if your preamp is having trouble driving that length of cable, it might be worth at least trying it. As I said, that is where my equipment is and I have very good results. But if my room would permit it, I would be inclined to set it up like yours is now, but my system is fully balanced so the long cable run is not a problem.
