Question for DIY people: Butcher block shelving??

Hallo, JD!
Yes, those Winters Lessons are a classic!
Maybe I should look into your (teddy) bears scheme..:)

Still crazy after all these years! (isn't there a song along these lines?) Cheers

Lapaix -- Sean or others... you might provide some insight: when I tried using an air bladder (bicycle inner tube) sandwiched between two maple shelves and alternatively used a Neuance on top, both sources SUBJECTIVELY seemed to slow down. I *did* use dividers between the top & bottom shelves (otherwise I'd be just compressing the air in the tube).
I know that's a very sloppy way of describing the sonic result; as I neither FFT'd the thing nor did I measure (too lazy) I have nothing else descriptive to go upon:(

Any ideas as to why?/what this is due?
TIA

Interesting, Lapaix. My *thinking* was along the same lines -- but hardly as articulate as yours! Thanks

On a different note, using weight on top of the cdp did change the resulting sound somewhat. The only word I can give is "bolder", a bit like increasing the VTF on a TT. Unlike the later, however, some upper level detail dropped further to the background... wether or not this effect reflect correct phasing (or whatever, stored in the cd) I don't know. I'm going to work on this further.

Indeed, Sean -- In my case, I don't know if I was reducing ringing (although it seems likely). My objective however is to come closer to the original -- that being what's stored on the medium -- hence my remark about "what's actually on the cd":) Cheers!

Thanks JD & Sean. Actually put things into perspective -- much obliged!

As you suggest JD, there was horizontal motion that I tried to limit using cones etc inbetween the shelves -- but no cigar. But by sort of stabilising the horizontal motion I was defeating most of the purpose of the vertical isolation... and anyway, admittedly whatever I did, as you note, DID allow horizontal movement at some frequency(ies).

My cdp is cumbersome (large & heavy, a bit like yours ~50 pounds). Suspended and sitting on its Neuance, I expect it resonates at a relatively low frequency (but have never measured it). If this premise holds, I should try adding mass to it, as you've tried, to gauge differences.

I'll try this WE and get back to you.

Speaking of extremely strange and VERY audible effects, let me relate the following:
I used to have a very large and front heavy pre (~60pounds the front plate was heavy). Inside behind the front plate in the middle, were "main" caps; on either side of these were more caps, one board for each channel. The motorised volume and relay-coupled selector were linked (as usual) to the back, and the actual circuit was suspended at the back, the plate holding the usual inputs outputs, and the power chord from the outboard PS.
The effect: when I placed a cone in the front, in between the component's two feet, the sound became LOUDER (and slghtly different).
Strange, no?:)
