Boost system performance via isolation?
Hi
I need help.
I found out last year just how important isolating devices can become. I've taken some steps in that direction but feel there may well be a better path than the inexpensive Vibra items. Which for the money surely are worthwhile devices.
In isolating components such as CD player, tubed preamp, and over a hundred pound SS amp. I have a rack from “HE..” (a bit south of Heaven, if that helps).
I do understand the rack itself, plays a big part but I’ve been unable to address that aspect as yet. So I’ve tinkered with it enough so the sound is pretty good now. Using homemade and mainstream products such as Vibra Pods. Currently Vibra-pod cones & pods, as well as doing some ‘layering’. Using a sandwich sort of configuration….
ON each shelf of the rack, from bottom up, I used a piece of ¾” MDF > CONES > ½” particle board (shelf) > Pods > component. Results aren’t bad but i would like to improve upon things, especially with the amp and preamp. Also a 400 disc carosel and a couple lightweight items too such as a DAC and DVD player.
I've done nothing with the amp... just CDP & preamp.
Anyone using something other than ‘Vibra-Pods’ & Vibra-cones, that have seen definite improvements in their system… I would sincerely appreciate hearing from you… and how it changed things… and naturally what those devices are.
I’m not looking to go off for tons of bucks here but would sincerely like to get an idea of who really does make effective isolation devices for components of varying weights andd function… eg., rotating, tubed, SS, etc….
Many thanks

I should explain. While rollerblocks are directly coupled to the shelf unlike isolation devices like sorbothane, pneumatic, or magnetic levitation; they are still undamped in the horizontal plane. Undamped IMHO, means the CDP rings and adds strange harmonic content. There was more detail perhaps due to the metallic feet tipped up the FR. Damping out the feet with stainless steel instead of aluminum material, rubber or cork pads between the metal roller surface and CDP case lessened but did not eliminate the problem. Maybe some folks would prefer what the rolling effect does to the sound, as I did initially; in the long run I did not think the sound was natural. |

Hello Blindjim, I do not know if you have looked into the isolation system I posted under my systems. I go through the products and reasoning for each. I have also attempted to discuss the philosophy that I have put behind my isolation. This is the culmination of ten years of experimenting with as many ideas as I could find. I hope you take the time to read this, my isolation system and feel free to to contact me if you have questions. I also suggest you read free tweak... and winter lessons and tweaks and how my system disappeared. This should give you plenty to ponder. I have spent the past eight years on this site focused on cables and isolation. There is a lot of information out there, and this is just my opinions, so... Good luck, it ALL makes a difference!!! jd |
