Oh sorry, I thought it was your room. Yes you are right about that compromises.

Juan

I thought I had too many panels until I saw the Joachim's room. Spectacular room treatment!
There's a problem in my opinion placing the rack so far away, you have to run very long interconnection cables, unless you use XLR cables of course, or long speakers cables.
To place the the NOS1 in an isolated cabinet is also a good idea that could be complementary of other anti-vibration treatments.
Great system, Joachim

PS. Joachim, about WAF, if a wife accepts the panels I think she will accept easily any cabinet hahaha

Again it could be the placebo but the sound with that viscouse pads seems fuller with a deeper bass, perhaps a bit darker but it looks to me like a more serious sound in the sense of more grown, more consistent sound. The image is very well defined. Now I´m using W8, non isolated Silverstone card and I haven´t touched the wire inside the NOS1 yet.

Looking around at home you can always find a solution. This is useful for back pain and ... to isolate the NOS1!. These little bags have some sort of viscouse fluid inside. The effect? not worse than the the rubber balls I had before, in fact not bad at all. Sure Peter has a more sophisticated solution 

Juan

Hi Alain,

Before opening my NOS1 I wonder if you noticed something after disconnecting the cable.

Incidentally, I think you just have to disconnect the black wire to avoid doing so in the USB cable that is more difficult. At least this is what I understood from Peter posts.

Best regards,
Juan

Edit: these are Peter words: "under the top right bolt of that PSU is a black wire; unscrew the bolt, detach the wire (it is not soldered), ...do NOT detach it from the USB interface as of now because it is too fragile there."

Some time ago I also used a waterfoot for my self

Oh, I see you are talking about the viscouse fluid or...was it water? It was water! I don´t know why I thought it was some kind of viscouse fluid...

Juan

Never tried those ESD (electrostatic discharge?) pads. I guess they are difficult to get. What about those waterfoot, what do they look like?

Juan

Peter, I did not get those pink pad with my NOS1. What kind of material is it?

Regards,
Juan

Peter, the dumpers I use have a felt underneath and the metal is demagnetized, there is no metal touching the metal plate of the NOS1. When I tap on the NOS1 plates with the dampers on it there is a deaf sound not like a metal sheet vibrating.
If you were talking about the plates to be attached to the inner part of the NOS1 what I wanted to say is some kind of dampening material glued to the inner part of the NOS1 plates.

This little brochure about Damping Tecniques for Noise and Vibration Control is very instructive http://www.earsc.com/pdfs/engineering/understandingdamping.pdf

Juan

Hi Alain, I could not answer with the laws of physics in hand, maybe others can do it, but what I can tell you is what I have seen in other electronic components, some of them have placed plates of some material glued to the inner part of the component plates with the intention to change the resonance or decrease the vibration.


Hi Peter, I could imaging that you already thought about it but what do you mean with "devastating"?, do you mean that isolating the plates could be for the worst?

Here I post some pic with the dampers, the rubber balls feet and some Vibrapods underneath.

After a few days away I returned home yesterday and connected the system to see what was going on with the famous isolated card. I put my favorite album, one that has voice and various instruments and after a few seconds I realized that the sound was great ... but the voice, that voice was not in the center, seemed rather to the left, maybe not, maybe the voice was back in some place or in all places at once, sh..t!, that´s what Peter said!, I thought. Well, as that seemed to be out of phase I changed the cables inputs in the amp to change the phase but all was the same. It was strange because the instruments seemed well placed, was the voice that was not located in any particular place. So, I decided to return the card to its normal situation by removing the insulation. Everything went back to its proper site. However the sound appeared to be a little harder, less sweet. I insist, the feeling is as if it was out of phase, although really is not.

At the same time the possibility of returning to W7 appears. It might sound better, do not know, when I did my testing I found that W8 was the best so far. What is the main reason to go back to W7? are we talking about to test W7 because we have the Silverstone card or do I missed something? Ok, I know that some people think that W7 sound better...

About isolation, I always use those iron discs on top of the NOS1 to avoid vibrations and some kind of rubber balls as legs. Peter, have you thought about the possibility to isolate the different plates of the NOS1 with some kind of absorbing material bonded to the inner side of the plates and even with some rubber tape in the junctions of the plates?. Anyway, it looks interesting that experiment with the carton but I think you have to upgrade the tool you use to fill the box with the viscous liquid. Throw away the watering can and watch this video. http://ecorptv.com/video/283/Instapak-900-Series

Hi Alain,

Yes, in my case I had less hum but I only could listen with the isolated Silverstone for a couple of days. What I remember was a fantastic sound, very enjoyable indeed. Peter was listening it for one week, I don´t know if being in the same situation would make me feel the same, if that´s the case it will be a small disappointment. I´ll let you know when I come back home and listen again for some more days. It could be also system dependent, as you say. Anyway, it seems that the experience is divided between those who perceived an improvement and those who not.

Regards,
Juan

Hi Peter,

For the ones that don´t use your PC and even for the ones that already have W8 installed could be some advantages buying your hdd, mostly due to the around 500 OS modifications. I wonder if there is other way to get those 500 modifications.

Juan
