Yeah but a PCB board is liable to vibrate just as much as casework. I think of PCB material as damper than steel and resonant at a different frequency. FR4 compared to aluminium I'd be more uncertain. Your probably correct but if the PCB is attached to the Casework it will vibrate along with the casework? only way to see if damping with Silent coat does anything is to suck it and see! |

Yeah, unless you happen to have a tool that precisely measures surface vibration, which is unlikely, you just have to experiment. A few years ago I found that nylon standoffs made for a mushy and masked musical experience. I thought I'd done something wrong with my soldering or circuit layout, but couldn't find a problem. Changing to brass standoffs corrected that. |

Everything vibrates at a different rate depending on material it is manufactured from so experimentation is the key I guess.
Thanks for putting me onto this stuff Bruce as it has made a significant improvement both attenuating vibration and improving SQ.
I have been looking at ways for taking as much vibration out of my system because every time I do some I hear an improvement. This is especially so as I play mainly vinyl and use valves. All susceptible to vibration.
I have spent so much time and effort doing this but never thought about going down the route you suggested. I always thought from the perspective of eliminating vibration from the outside rather than from the inside.
I have one piece of my set up that is still a nightmare and if I could sort it I would take a huge leap forward I am sure. This concerns my turntable motor which is independent of the turntable and vibrates like a box of frogs. I may try and work out if I can use some Silent coat with this unit?

Listening to some more well played vinyl tonight and I am astonished at the sound I am getting since damping the amps.
I feel the transparency to the recording has increased massively like something has been taken away that I had not noticed before. Quite strange really and difficult to put into words. Almost like the system is invisible and you are in or part of the recording?

Just a few more observations regarding the Silent coat damping of the Croft amplifier cases. I have noticed a lot more precision with acoustic instruments especially where notes stop and start. The background to the recording also sounds quieter and the acoustic space around the instrument is more noticeable. As I mentioned on first hearing the difference with the damping on the cases everything in the recording is now more focused.
Sometimes you don't know what is there until it has been removed?

I had 5 or 6 sheets of Silent coat sitting around in the garage. I decided to add a sheet under my poweramps bamboo isolation platform which also sits on a sorbothane sheet. I've added a little intrinstically to the Croft Epoch preamp - some on the Tx's and around their bases. It can'y do any harm and can be easily removed. Slight more bass definition and maybe a sense of ease to the soundstage. Notes just seem to float bewteen the speakers.

The Silent coat maybe very good as a layer between turntable isolation platforms. Currently I use Vibrapods so may swap these for Silent Coat. |

I looked at minimising vibration getting to my TT. So, the silent coat in the preamp was one way of trying to combat that. I also have my TT sitting on Townshend seismic platform. It's difficult to say how things have improved the soundstage. I'm at a stage now where I can't be that far off the zenith of what can be achieved with what I own. I'm very reluctant to try new gear and prefer to see how far I can push currently owned gear. Presently, my soundstage has several layers of depth, I'm blessed really in that I can hear musicians sitting and playing, spatially in differing areas of the soundstage. I think that adding the silent coat has helped things, how much? I'm afraid that's something I'm not going to try and quantify, things are sounding pretty bloody good at the moment!!!!!!!!!!
