RE: Can Passive Dedicated Line Conditioners Benefit Sonically from Proper Vibration Mgmt?




Bear in mind that I mfg'er $10k racks and this ain't them. This mini-rack was intended to be just a proof-of-concept made out of some spare hardware I had on hand.

Just rememeber that form follows function and these are all spare parts I had laying around, ok?

What we have here are:

. 4 fabulously performing Foundation Research LC-10 passive, dedicated, bi-directional line condtioners.
. Small bars on top and bottom.
. Solid and hefty copper plates underneath each pair of LC's.
. Threaded rods with red springs covering the rods.
. My custom points to ensure the rack is making solid contact with the sub-flooring by piercing thru the carpeting and carpet pad.
. Some ratcheting straps for safety just to keep things from popping out when compressed.
. Some soft material between the upper bars and top plates just to preserve the LC's fine condition.
. Not pictured is a rather large cylindrical piece of stainless steel that weighs perhaps 35 lbs. for mass loading.
. Note that the bottom row of LC's are maybe 7 - 8 inches off the carpet to minimize potential electrostatic charge from the carpet.
. LC's are under about 300 lbs. of compressive force as they are sandwiched into the shelving system.

It's not ideal but I was able to follow most of my preferred methcologies as I just slapped it together after hand-sawing the 3/8" threaded rods to length.

Between the 2 solid copper plates and the oversized stainless steel cyliner on top (not shown), the 4 LC's, and the misc. hardware keeping it all together, we're probably looking at about 80 lbs. total.

In the past 18 days I've received 6 fairly reasonable performance gains that I'm aware of.

I've been wanting to try this for years but never had the time. Am I surprised that I received any positve results? Well, yes and no. Nothing about proper vibration mgmt surprises me any more. Overall, I expected maybe half the gains I've received thus far.

But this proof-of-concept also tells me that if I incorporate the LC's into my regular rack and apply the exact same methodologies with the LC's as I do any other component, or perhaps design a custom performance-oriented mini rack dedicated just for the LC's, I just might be able to double or triple the gains recently received.

On a performance hope scale of 1 - 10 where a 10 is hitting it outta' the park, I'd probably list this effort's resulting performance at a 5.5 or 6. Not bad for 90 minutes worth of work and just enough spare parts to execute it somewhat poorly.

And now I need not wonder any longer.
