Joachim, you could use the toilet perhaps. But then the "toilet test" won't work any more !

Peter, be open minded please Pearson, Michael Fremer and some/many others are using their big speakers as “near field” monitors, and then you hear the “output” from the recording room (plus possible colorations from the system) only. The SQ is amazing and you are sitting in the middle of the performance. Now I understand why Mani is so enthusiastic with his AKG K1000 headphones. Joachim

Hi, I read this passage: ------------------- Since I was expecting Harry Pearson to be a human being and not a mythical character, other than that odd sensation of feeling his feeling my disappointment with him, I was not at all disappointed—though I was taken aback by the size of the mythical listening room in which he had the giant Infinity IRS loudspeakers and Goldmund Reference turntable. The room was barely large enough to contain the speakers! You sat but a few feet from these enormous monoliths. How could this sound any good? But as soon as he put on a record I heard good that was way gooder than anything I'd ever before heard and those four giant columns completely disappeared leaving a holographic three dimensional picture the likes of which I'd never before heard. here: www.analogplanet.com/content/audio-legend-harry-pearson-passes-away-------------------------- My speakers (not tilted) are 2,20m apart and my new listening position is now 1,5m away from the plan of the speakers and I hear that “holographic three dimensional picture”. I’m sitting just in front of the soundstage. It seems that my listening room is too big and I have to move the components into a smaller room. Joachim

But the barrydiamond idea with the bicycle tyre - ikea board - bearing really did it. Most stunning improvement it the depth of the soundstage. Unbelievable nice now. Will try the same with my amplifiers this week. For the bearings I use magic dreams of omicron. The tyre is a 14" innertube.

Here is something similar to Peters idea- floating platforms - found here: http://www.barrydiamentaudio.com/vibration.htm--------------------- Roll your own In order to provide a means of sampling what seismic isolation can do for your system, what follows are instructions for making your own equipment supports. Items 3, 6, 7 and 8 pertain to roller bearings. These can be used without air bearings to provide horizontal and rotational isolation only. Air bearings can be used to provide vertical isolation only, as in those commercial racks and platforms which use air bearings. Best results however, will be attained by using a combination of these to achieve multiple-axis seismic isolation. 1. Get yourself a bicycle tire inner tube for about $1.99. I use 18" inner tubes. The larger the circle described by the inner tube, the easier it is to balance the gear atop it. 2. Obtain a piece of plywood an IKEA board to use as a platform on top of the inner tube. I use 1" maple ply measuring 20" by 20".3. Go to a crafts store and purchase 3 wooden, usually pine, Easter egg holders and some marbles for a total of less than $2.
4. Place the inner tube on your shelf. Inflate it only enough to hold the component up off the shelf. Too much air and you won't get the benefits.
5. Place the plywood on top of the inner tube.
6. Place the three Easter egg holders on the plywood platform in the largest equilateral triangle that will fit under the gear you are going to support. I suggest trying your CD player first, though the benefits will add up as you float your other components as well.
7. Place a marble, or even better, a ½" steel ball bearing, in each of the Easter egg holders.
8. Carefully place your component atop the marbles, so they alone support it, holding it up so its own feet do not make contact with the plywood platform.Joachim EDIT: The main idea is to get the vibrations into the IKEA board.
