Butcherblock Acoustics "feet" effecting sound and isolation
Hello, general question here do you believe the feet being used under a Butcherblock Acoustics platform effects the overall sound? I'm using metal spikes resting on metal decoupling discs that I ordered from Butcherblock instead of the stock rubber feet it came with. I have maple butcherblock under my phono preamp (3 inch), all tube preamp (3inch), and amplifier (1.5 inch).
Also do you think I could be over isolating with all that? I'm gonna do some experimenting this weekend but just wanted to see if anyone had thoughts or opinions on it. I've read good and bad things about isolation and over doing it. Thanks for any responses!

+1 Excellent explanations. I have a high end Silent Running Platform isolation platform under my turntable (the most sensitive component). I am using sandwiched elastomer / ridged platforms (Black Diamond Racing composite), with Nobsprings on my other components. Each change has improved the sound. As I can afford additional isolation platforms I will add to other components replacing the inexpensive Nobsprings.. |
Dang, I'm going to sound like Amir. The right way to do this is measure the frequency and amplitude of the device you want to isolate. The next best is to put your gear on solid bases and hope you are addressing the issue. I've been dragging a 200-pound piece of granite around for 50 years...not sure if it works but it makes me feel better. |
@russ69 Makes you feel better is key. Your granite may be large enough mass that the noises in the room cannot affect it. the natural frequency of a spring system (from memory to excuse me if I get a constant wrong) is sqrt(k/m) where k is the spring constant. so your very large m makes the natural frequency so low that it will not get excited by sound. |
