Coating the Karik with lead
Posted by: quincy on 12 October 2001
Last year my buddy Dave suggested that I stick a panel of Code 4 lead sheeting onto the underside of the Karik 3 to improve the sound quality of the system.
He was on-the-button ... day versus night.
Any of you cats tried something similar ?

Maybe he was suggesting that you drop it in the river afterwards.

The only lead that I drop into the Cumberland River is on the end of some fine trout line.

...but last Monday I noticed that the top of my Sony ES series receiver was vibrating like crazy. It is a holey kinda thing which makes it flimsy. I placed a 5 lb or so bag of lead shot on it and wow - what a difference. More dynamic, quieter, and waaaay more musically communicative. One of those, "I'm hearing my CDs for the first time" kinda things. Haven't checked the underside.
I do remember that my Naim CD3 did not like having much weight placed on top.

A one time poster used to sandwich his CDX between layers of glass in order to both support and dampen it.
Basically the player sat on one or more layers of glass which were separated/supported on ball bearings that rested within fastener nuts. The glass sheet on top was 'stuck' on with three or four large blobs of Blu-Tac. It came to be known as the 'Vukwich' in honour of its creator who was aptly named after a wild dog. (Vuk, n., p. Vook; a wild dog that roams in packs (Websters)) 
I believe that some forum members may be still be using this method of isolation in leiu of investing more heavily in dedicated supports.
You friend Dave's lead idea sounds like an easily reversable tweak worth trying.

Dave's tweak is not reversible.
The lead is permanently held in place by Walmart's finest cyanoacrylic acid.

What about a mutant version of the naim mass damper? Maybe small blobs of blutak in the corners of the lead sheet for easy reversability. Also provides dissimilar materials for vibration damping (insert something scientific here...please).

Blutak may be fine and dandy for the British climate but summer nights in Memphis would not be conducive to good listening when the Blu lost its tak.

Don't be silly all of us engineering types know it's Froggle's coloring and not his mass causing the distortion.

Ever spent a July night in North Carolina? It's so damn sticky I've seen rust get up off the metal 'n walk away saying "f*ck this sh*t"
yea boy!

Silly humans us.... I was going to model my predictions using Catastrophe Theory, weenies and wood chips .
He deserves extra flies tonite!

Quincy,
Do you have any pictures? Was the lead plced just on the base plate or the outer case also?
Would strips of lead tape do the same job? Easily reversible, self adhesive. You can even make patterns!

Lead's not much good for one's health - better to protect yourself by installing inside the Karik.
Easier to conform to contours by applying heat, melting lead, and pouring into the Karik. Allow to cool sufficiently before attempting use, though! ; )
disclaimer : if you're dumbass enough to actually do this, don't come crying. Oh, and make sure you tie your shoelaces before walking down stairs.
I was serious about the lead dangers, though.

Rico,
I suspect the fumes from melting the lead might be worse than environmental contamination from lead sheeting.
cheers, Martin

Hm.....
it must be devided by 4pi.
Reason here is that he neglected the third and forth dimension.
OK, maybe in a "flat earth" calculation he could skip
the third dimension, but at least we all know how important TIMING is ;-)
So, he missed the time in his calculation....
If you now integrate over your hamiltonian it gives the corect answer. (42)
Enjoy live!
