Equipment Stand placement?


With so much focus on reducing vibration and other environmental detriments to good sound, I wonder where the best placement for the equipment rack in a listening room would be. It seems that with rear-ported speakers that are out from the back wall, that putting the equipment along the back wall between the speakers would be subjecting it to increased vibration. Putting it along a side wall puts it more in line with the first reflection point, and therefore more sound waves.

What are people's preferences for sound rack placment and why? -Kirk

Well there is theoretical ideal set-up, and then there is real world set-ups. Ideally you place amp only between speakers allowing short speaker cables and run long ICs back to rack along side walls, balanced ICs being ideal.

This is not so much because of sound wave effect on gear which will happen anywhere in room, but for soundstage/imaging enhancement which is improved with no obstructions between speakers. Also psychologically stage
seems deeper/wider with no obstructions especially if you use spot lighting to enhance the illusion.

Now in reality not many audiophiles do this because you almost never see 15-20ft ICs for sale here wich would be needed for ideal set-up. I would guess close to 90-95%
of audiophile systems have rack between speakers.

Also if you pull speakers out 5ft or more from speaker wall
rack effect has less negative impact on soundstage when placed between speakers.
I tried both, with rear ported speakers on a side wall and between at the back wall.
My ideal thought would be to have the power amp in the middle (if stereo) or closest to speakers (if mono) with shortest speaker cable length and longer interconnect leading to a side wall equipment stand placement.
Having not tried the different cable length but comparing with same length I could not tell the difference it made to the sound (even at high volume) with placement at side wall or between at back wall.

My current set up (in a new room) has the equipment in between on the back wall. My observations are similar sound but varing degree of change to the sound when trying out any new isolation product.
kthomas: earlier this year, i reconfigured my system placement to replicate what megasam calls the "theoretical ideal set-up." my equipment rack is now on the right-side wall, aft of the first reflection point. the only thing between my speakers is my amp. when i moved the rack, i also put up 7 asc sound panels between and in back of the speakers (there had already been tube traps in the corners.) this relatively simple change brought about, for me, one of the biggest improvements i ever made in my audio system. the soundstage became much deeper and wider. image placement was more stable and airy. bass was tighter and deeper. yes, this required a single 7 meter run of balanced interconnects but it was well worth it in my view. indeed, i'll never allow a rack, or anything else but an amp, between my speakers again. -kelly
