Redwiki - About racks, shelves...


Reading your Neuance thread peaked my interst with racks, shelves and footers and if you don't mind I would like your opinion on my setup. RACK> Lovan (lead-filled) triangle rack
with custom 1/2" glass shelves supported on hard rubber footers on rack. TOP SHELF> 3cm polished granite rests o (3) aluminum TipToes with rubber (on flat bottom) between cones & granite. Cone points sit into dimples of each rack post. Another 3cm granite shelf - with (5) Vibrapods between - sits on top of the first granite shelf. VAC TRIODE AMP> Rests on top of top shelf. Stock footers have been replaced with Vibrapods screwed into the amp, Vibrapods sit on B.D.R. "ThoseThings" bases (only). DDS.PRO TRANSPORT> Bright Star Audio Big Rock platform sits on glass shelf, another 1/2" glass base rest on the Big Rock with Vibrapods between. Transport rests on glass base w/stock footers. M.P.S. (power supply) / DAC> M.P.S. rests on 1/2" glass shelf with Vibrapod footers. Dac sits on M.P.S. with down-pointed B.D.R. cones between. 10 lb. lead bar rest on dac. PASSIVE LINE ATTENUATOR> Sits atop 150 lb. concrete Inoic column. Vibrapods between column & Bubinga 2" (hardwood) base. Down-pointed B.D.R. cones between wood & passive. VPI brick sits on top. SILVERLINE SONATINA SPEAKERS> Rests on 24x12x4"
polished granite platforms. Stock footers replaced by up-pointed Poly Crystal cones which sit on 3x3x1/2" Ebony. SHUNYATA HYDRA PLC> Rests on 15x13x6" polished granite with down-pointed B.D.R. cones. R. Crump suggested i dump the "kitty box" and replce w/Maple platform. The Neuance bases look intersting an alternative. While still evaluating the Hydra's contribution (burn-in process) - I'm looking for a more open, neutral sound with less additive devices to color the presentation., thus considering re-evaluating my set-up.
Whats ya think? Thanks in advance. Reference system: http://

Oh, yes: the components. All on the heavy side (12-25 kgs) each, one comp. per shelf. Power supplies (3) not on rack.
Sorry.
Gregm. Because neither the Corian or Perspex are totally neutral, you may get the best result using Corian on the source (and maybe also preamp) and perhaps Perspex on amp. Mixing different shelf materials together will hopefully avoid any too obvious resonances. I found Corian everywhere to be something of a problem. By the way I did find Maple Butchers Block to be OK too - it sounded slow and murky, but not nearly as much as MDF did. It was able to be improved with cones. I mention it because it may be OK with the very heavy stuff and provide still more variety to your tuning of resonances. I believe you have got my point on the steel wire - it sounded very much like there was a steel stringed guitar playing along with the music.
Thanks for sharing the information. I'm in the mist of evaluating my Shunyata Hydra PLC among other unforseen changes (tube dying) so I think I'll let everything settle
and then look into my rack / shelves / footers.
