To Hevacl, does the sale of rubber and cork squares appear in the audio accessories section on Amazon, and who makes them, or is it DIY?? I do not want to elevate the slab more than one half inch off of the surface of the wooden table. Thanks, Jim
How Good Is A Marble Slab at Deadening Vibration
I have a marbles slab that is approx. 42" X 16X 2". A left over insert from a coffee table. I would like to lay it on top of a plant stand table that is 50" X 18X 30" The slab weigh about 70 lbs. II think I have enough space laterally to position a Rega turntable, a Bel Canto line stage, and Rega Apollo CD player and a pair of Red Dragon monoblocks, that could easily be stack vertically if necessary.(Also could place them on the bottom shelf which has a slight V-shaped dip ...probably a run off channel. This would save me three feet of speaker cable on both channels is placed near the bottom)
The plant stand is made of wood and has fairly massive "L-shaped" legs. The table weight is about 40 pounds.
My thinking is that a marble slab should provide excellent isolation from vibration. The only drawback is the left side of table will only be a foot from the right speaker. So I would start the progression of components from right to left to increase the distance to the speaker in question. Would like opinions from members about the pros/cons of this set-up. Thanks, Jim

SuunyJim, I knew bookmarking this would come in handy some day: http://www.supersoundproofingsales.com/products.asp?dept=25 They have any size you'll ever need. All the best, Nonoise |
To those who responded: Though final conclusions have not been reached, Operation Marble Slab has been generally successful producing benefits in midrange clarity, some increase in bass, and overall, a more coherent presentation of the music. However, nothing was startlingly different. The following music was used: "E Power Biggs Plays Bach" David Bowie's "Ziggy Stardust"; Steely Dan "Can't buy a Thrill" and one Belle and Sebastian's track titled Lazy Line Painter Jane...hard to believe a calliope would be converted into a powerful rock instrument; Lastly, Mott the Hoople's LP titled "Mott" particularly the last two tracks side 2: "I am a Cadillac" and I Wish I was Your Mother" One anomaly: On some music there seemed to be less slam and dynamics, mostly on LP's I have heard deeper pedal notes on the Bach LP which was gifted to me 37 years ago. On the Mott the Hoople LP, there are two mandolins that drive the tune. "I wish I was your Mother"; they had less sparkle at the top of their range from what I can recall from before. The CD playback seems to have reaped the most sonic benefits from the marble slab. Finally, though I cannot quantify it, I felt that I could hear or at least identify the weaknesses of CERTAIN COMPONENTS, AND CABLES. Mainly, the Red Dragon monoblocks amps which overall are very neutral, but have below average lower bass and resolution. In addition, the Morrow MA-3 IC which connects a Musical Surrounding Phenomena II phono stage to the Rega P3-24 crowned with a Dynavector 10X5 spike. MA-3 just did not cut it Transient response on some LP's sounded slow. OK,I know this is a subjective impression; it is probably because I have NEVER liked it to begin AND WAS NON-RETURNABLE BECAUSE OF BEING USED. The other weak link is the Audio Art SC-5 standard speaker cable which is good, but not the best wire for the AZ Adagios wide frequency response....that is why I keep looking for and asking about better speaker cables in various threads.... SO THAT IS IT FOR NOW!! I will try the cork and/or rubber matting as recommended by BW, and Hevacl. Thanks again to all. Jim |
