Even for concrete floors structureborne vibration is an issue, trumping airborne vibration. The Earth's crust motion forces the building structure, including cement slab, to move at low frequencies circa 0-20 Hz.
Isolation for DAC/Class D Power Amp
Hi,
There are many threads on isolation, but I have a more specific question. I understand isolation has great benefits for mechanically sensitive devices such as speakers, turntables, CD players and tube equipment. In your experience, do fancy racks, isolation, coupling etc. have any major improvement in sound with (solid state) DACs / Class D Amps. My flooring is very solid: hardwood glued on to concrete, so floor borne vibrations are not really an issue. The only remaining issue is air borne vibrations from the the music itself.
Thanks.

I have done extensive experimentation with isolation of my own components, and every piece has benefited. However, what sounds best under my tubed integrated amp (Final Labs Daruma) may not be what sounds best under yours. With that said, to answer your question, I'd say your equipment would most likely benefit too, but it will require experimentation on your part to find what works best. |
Many times in the past I have trumpted the benefits of vibration control and the benefits it has reaped and saved me from changing. I am using Bright Star peices for both my CD player and my integrated amp and will never part with them! I have the CD loaded with an Air Mass/ Big Rock and have 2-2 lb. Brass dampers atop it from Eden Sound and for sure as I added peices (starting with the Air Mass, then Big Rock, Then Eden) the differences were jaw dropping for me, so much so that I purchased a Big Rock for the integraged (SS) and heard further improvements. When I first started in digital I realized the differences using Sim Feet but, I now understand better (from hearing) what mirco vibrations due. Now, oh course, this is just my hunble opinion but hearing has made me a very strong beliver. |
... only remaining issue is air borne vibrations from the the music itself. Not necessarily. How about vibration generated within each device? Some (as me) believe it requires a path for escape.
