In Reply to: ENGINEERS: State your cases for or against isolation devices posted by Kristian85 on October 1, 2003 at 14:12:09:
Hi Kristian85,I must agree with the Duke's assessment regarding the trollish nature of your post. That said, a few considerations come to mind:
1. You mention only "sound transmitted by air" but not sound which follows the much easier path through solids. I'm referring to direct conduction of externally generated sounds via the structure of the listening room, into the components via whatever supports them, i.e. racks, shelves, etc. In my experience, these are the most sonically degrading vibrations and they tend to be very low in amplitude and frequency.
2. I too have never seen what I deem to be a satisfying explanation for how these vibrations effect my equipment. There have been some bits and pieces, for example, the microphonic nature of wire, not to mention same for tubes or the sensitivity of clock circuitry in digital devices. But overall, I find it difficult to accept that a truck changing gears 1/4 mile away or the ocean tide are somehow interfering with the performance of my stereo system.
The presence or absence of a satisfying explanation however, has no bearing on my experience, only on my understanding of the experience. These are two quite different things.
My experience has been that isolation (and by this I refer to the use of compliant equipment supports with resonant frequencies in the low single digits, like roller bearings and well implemented air bearings) has resulted in consistent, repeatable and wide ranging performance improvements in all the devices where I've tried it. This includes CD players, DVD players (where the picture improvement is as easily visible as the audio improvement is on CD players), loudspeakers, power amps, pre-amps and even power strips. While the effect is not as pronounced on solid state, no moving parts devices as it is on CD players or speakers, it is audible, consistent and repeatable nonetheless.
I know of no measurement that can quantify the perception of depth in stereo audio reproduction or even in our visual response. Yet, I can easily hear it on any decent system when such information is in the recording. And I can easily see it visually as I discriminate between objects near and far.
I repeat: The presence or absence of a satisfying explanation however, has no bearing on my experience, only on my understanding of the experience. These are two quite different things.
Happy Listening!
Barry
