Equipment setup..does & donts

Veridian, so long as any room is oxygenated and/or directly or indirectly anchored to planet earth there is no such thing as isolating gear from vibrations but yes being in another room can certainly help minimize some (not all) of the sonic harm induced by improperly managed air-borne and floor-borne vibrations.

Moreover, internally-generated vibrations (eg motors, power supplies, etc.) will continue to induce the exact same sonic harm regardless of what room they are in.

Since air-borne and internally-generated vibrations can be addressed the exact same way, it makes sense (to me anyway) to properly deal with the vibrations and if I do then it won't matter which room the components are in and I won't have to worry about 30 or 40 ft speaker cable runs either.

As for the height of the components affecting the soundstage, most likely it depends more on how far out into the room the speakers are placed. If the speakers are only a few feet from the back wall then raised equipment may (or may not) compromise the beauty of a full soundstage. But in many cases if one's speakers are this close to the back wall they probably have bigger issues to deal with anyway.

If the speakers are say 6 ft or more out from the back wall I wouldn't worry much about it.

-IMO

i keep my components on the floor, on a maple base, with anti resonant materials under the component.

my amplifieres are behind the speakers and speaker cable is 6 feet in length.

Don't place the speaker's behind the rack and expect to have fine sound. You'll see what I mean if you check the system pic of a member in the thread asking about how many watts is too much for a 91db speaker.

If you can do as i have and put your system rack in the room behind your listening room you can achieve a better sounding system due to no large rack between the speakers. This also is a good move for you vinyl playing audiogoners. No more micro vibrations from playing at loud levels. I got this idea when replacing the floor and it has worked out really well in two ways sound and looks.

Stehno, as a point of courtesy, you might try spelling my name correctly when you directly address me.
