To couple or decouple? That is the question.


This is one of my favorite subjects and pet peeves.Is this just a matter of semantics or a misrepresentation of the principles applied in the set-up of equipment. My experience tells me that coupling is what you work for. This is the principle that is expoused in the early Linn literature. The mechanical connection that doesn't introduce or take away any information. This seems important with componets with transducers primarily turntables and speakers. Different materials, like sorbothane, are used to attenuate frequencies but are used in conjunction with metal cups to physically couple to your stand, shelf, floor, etc. Coupling also allows mechanical/acoustical energy to travel away from a componet. The designers at Mission in the early 80's were right on to this. Questions or comments please.

Unless it is generating the movement and assuming it is tightly coupled to the stand. I do like the Neuance shelves on my Mana stands, however, as they have continuously variable resonance frequencies and are on the Mana spikes.
Words of wisdom:

True coupling would be to run a long I beam below your equipment into bedrock. This would add the mass of that bedrock to your system mass. There is no real isolation as everything you use has a resonant frequency and your choice is where you want it. This is true for air and magnetic isolation also. In fact coupling is also isolation but with a very low resonant frequency.

I wonder what the Sistrum cult followers have to say...
I actually worked on a project where I contracted a mason to lay cement block in a customers basement.The block went from this guys basement up through a hole or a square I cut in his living room floor.The block then went about knee high in the living room and his Oricle turntable was mounted on the block that went from his basement floor to his living room.He was able to get unreal SPL's out of the damn system based on a turntable.
Isolation by nature of materials used is a storage medium. Why would one, find it desireable to have unwanted energy stored in or around their electro-mechanical devices? I think having this unwanted energy present would reduce the efficiency of the device, in, under or surrounded by the isolation vessel. Also, now the surrounding storage vessel, not infinite in its capacity will release stored collected energy over a unpredictable amount of time and with unpredictable amplitude. This unpredictable storage and release behavior becomes even more problomatic when some of this stored energy will be released back into the very device it is trying to isolate.The sonic signature of the storage vessel will be blended with the intrinsic sound of the nearby electro-mechanical device..Whats worse than having the influences of one unpredictable storage medium? How about two or several or lets retune our whole system with a multitude of unpredictability.Tom

Good-day:

Robert from Star Sound Technologies, LLC here as I feel the need to respond and request that a correct understanding and terminology be employed here.

This “cult” image and proper name calling as some of the members here have assigned to our clients is rather absurd and intellectually incorrect wouldn’t one think? Shall we call our clients audiocults or philecults or better yet - Starcults?

We have manufactured the Audio Points® product for fifteen years as they remain the oldest surviving yet flourishing retail product of its kind in this industry. Sistrum Platforms are a well defined advancement of that invention. Would not all these Audio Point clients be labeled cultists as well? That would mean there are now over 80,000 satisfied cult members out there, somewhere.

Plus, let us not forget to include some of the finest writers and editors in our industry who review and employ our products within their reference rooms, shall we label them and their publications as cultists too?

We always relate to our clients as passionate listening enthusiasts or even more so our very good friends. In order to achieve such a high standard amongst these people, who always seem to rally around each other, you must first have to provide them a product that musters all that energy, vitality and musical feel and always be there to answer all of their questions maintaining customer service as the premium product within our inventories.

We do take a very personal offense to this on-going negative correlation between our products and clients who favor them. Therefore we request that this name association stop. We value our client’s reputations and recognize them as some of the keenest listeners in the world.

Please do not associate our clients or products again with the term “cult”.

Thank you and as always – Good Listening!
