Tom, I've reconsidered my response to your query regarding the cover plate. I probably don't know what I'm talking about here but I'm thinking the 60hz line frequency may be setting up a mechanical amplifier in your panel. You may want to experiment by damping the cover plate with something. Maybe smearing some silicone rubber on the back side of the plate?
What Does Holographic Sound Like?
And how do you get there? This is an interesting question. I have finally arrived at a very satisfying level of holography in my system. But it has taken a lot of time, effort and money to get there. I wish there had been a faster, easier and less expensive way to get there. But I never found one.
Can you get to a high level of holography in your system with one pair of interconnects and one pair of speaker wires? I don't believe so. I run cables in series. I never found one pair of interconnects and speaker wires that would achieve what has taken a heck of a lot of wires and "tweaks" to achieve. Let alone all the power cords that I run in series. Although I have found one special cable that has enabled the system to reach a very high level of holography -- HiDiamond -- I still need to run cables in series for the sound to be at its holographic best.
There are many levels of holography. Each level is built incrementally with the addition of one more wire and one more "tweak". I have a lot of wires and "tweaks" in my system. Each cable and each "tweak" has added another level to the holography. Just when I thought things could not get any better -- which has happened many times -- the addition of one more cable or "tweak" enabled the system to reach a higher level yet.
Will one "loom" do the job. I never found that special "loom". To achieve the best effects I have combined cables from Synergistic Research, Bybee, ASI Liveline, Cardas, Supra and HiDiamond -- with "tweaks" too numerous to mention but featuring Bybee products and a variety of other products, many of which have the word "quantum" in their description.
The effort to arrive at this point with my system has been two-fold. Firstly, finding the right cables and "tweaks" for the system. Secondly, finding where to place them in the system for the best effects -- a process of trial and error. A lot of cables and "tweaks" had to be sold off in the process. I put "tweaks" in quotation marks because the best "tweaks" in my system have had as profound effect as the components on the sound. The same for the best of the cables, as well. For me, cables and "tweaks" are components.
Have I finally "arrived"? I have just about arrived at the best level that I can expect within my budget -- there are a couple of items on the way. In any case, I assume there are many levels beyond what my system has arrived at. But since I'll never get there I am sitting back and enjoying the music in the blissful recognition that I don't know what I am missing.
I should mention that there are many elements that are as important as holography for the sound to be satisfying, IMO. They include detail, transparency, coherence, tonality, and dynamics, among others. My system has all of these elements in good measure.
Have you had success with holographic sound in your system? If so, how did you get there?

Tom wrote, "Single speaker demo rooms are the only way to audition speakers without undue influence. Empty metal containers with electronic circuitry inside are also passive radiators even when not plugged in. Audio furniture tv monitors all building materials are passive radiators. As you know everything makes a difference..for better or worse is amatter of one's own perception or not." Not to belabor the point any more than necessary, for the sake of argument let's confine the items to those that cannot be construed as "passive radiators" - LPs, cables, CDs in paper or plastic sleeves (as opposed to jewel boxes), books, magazines, newspapers, telephone books, plants, flowers. If removing any or all of those items from the room improves the sound then the passive radiator theory cannot be the explanation. Geoff |
09-28-12: MapmanThanks very much, Mapman. Your assumption is correct -- I have never had an affiliation with anyone or any organization in the audio industry. Nor with any consumer product, for that matter. My background is in defense electronics. Regarding various statements that have been made by others to the effect that opinions about tweaks are invalid unless the particular tweaks have been tried: While opinions can and will legitimately differ, and widely, about where to draw the line, I would submit that there must be SOME finite limit to the degree of apparent absurdity of a tweak, beyond which it can be rejected a priori. IMO, a lot of the tweaks that have been mentioned and/or linked to in this thread, especially in the recent parts of the thread, exceed any such limits that are conceivably within reason. And, frankly, I doubt that anything constructive can result from discussion of them, which is why I haven't posted in this thread in recent days. Regards, -- Al |
Geoff When the concert hall is full and there are not enough hangars in the cloak room and the audience takes their wraps to their seats with them this passive device now on their laps changes the time and energy response within the hall. These additional passive devices were added to the acoustic volume of the hall and are not part of the collective displacement of the hall patrons as intended by the acoustic designer. They are passive and displace air with various forms of reactive mass. Tom |
