Sound is too thin. What to upgrade, add or remove?

Thanks everyone, thanks for the suggestions. I will try n work with speaker-placement first before going further; however, there is limited scope of moving the speakers closer together unless I move them forward enough to clear the credenza and then partially put them in front of the credenza; this could potentially have a PAF (see Ozfly’s note for explanation) factor. I will see what is workable on this front. The speakers are not toed in as per Kharma's manual, and if I recall correctly, they’re about 7-ft & change apart (woofer-to-woofer) now. According to the manual the speakers should have a clearance of 4-ft to the back wall – I think I have a little over half of that. The ceiling height 10.5-ft could be another issue, not to mention the bowling alley like floors (actually bamboo). The wall on the opposite side of room (opposite from stereo) is also far away, say about 22-ft. So yes, I agree with you all, the “room conditioning” is the weakest link in this setup. The problem however is, the room has to double as our living room and therefore, audiophile type commercial grade conditioning panels may not work for this application. I have to resort something a bit more clever - for now cork based modern art comes to mind :-) No really, you've given me plenty to keep myself away from bars for days. Thanks again.

a quick update: just got home from work and checked the distance between the speakers (woofer-to-woofer). I was way off, it is close to 10-feet - way too much i think. Here are the corrective actions I've taken thus far: I pulled the speakers out so they sit 4-ft away from back wall; narrowed the in-betweend distance to 8-ft so they overlap the credenza slightly; moved the rug around, it is now sitting a 1.5 ft in front of both speakers. I hear some changes but let me continue listening for a while and try out different recordings. Will update shorty.

Again, thanks a bunch...

ok folks - the sound did improve but not by huge margins. The imaging was certainly more defined, and the overall sound felt less chocked. BTW, I also liked this somewhat more near-field listening position as the speakers were now pulled forward by 2-feet. Unfortunately I ran out of testing and listening time, we had guests over!! I will continue to refine this setup based on all your suggestions. I'll separate the preamp, remove the PS outlets etc. I may also put a layer of padding under the rug.

Sol322, to anwer your questions -- i've had this setup for well over a year; and no, i did not add and/or remove any furniture etc. what i think has been happening is, i've started to go to more live acts in smaller settings lately.

I just wanted say, I'm quite moved by show-of-force - thanks :-)

Cello: Happy to see you coming to rescue outside the Supratek thread :-) I have already started scanning a’gon for a hydra-4 plus some replacement PCs. Will keep everyone posted.

Nrchy: I looked at yours as well as a few other Kharma based systems. I feel you may be right about the in-between distance. I guess I’ll do the best I can for now. Nrchy guest what we have another things in common, I too am motorcyclist – 1997 BMW R850R tour bike:-)

Just wanted to mention that I live in a NYC (pre WW-II) building which means, below my sub floors there is a concrete floor that's at least 8" to10" thick. It is quite solid and stable, no bouncing floors here like you might see in a traditional wood-frame structure. The credenza I use (blue thing between the speakers) instead of a component rack is a very sturdy Italian made unit, it is not a rickety Ikea thingy as it might appear in pictures, therefore, as far as any structural vibrations are concerned, my would say it is minimal. However, I started my search for a Hydra-4 conditioner, a few Symposium shelves and a couple of replacement PCs. I’m also thinking of swapping out the Valve-Art KT88 with some ballsy Svetlana KT88. Will keep you posted. Thanks everyone.
