RE: Clean power for Devialet - David A - 19-Jan-2019 Well, one +1 and one -1 :-) I'll take that as meaning it could go either way and I'll agree with that, "Audio is subjective and each to his own" to quote audio–engr. My experience was that I found that the results of stacking vibration control products was unpredictable, tended to reduce one problem at the cost of exacerbating another problem, and that the overall result of a combination was rarely better and usually worse than the result with whichever one of the stacked devices I preferred on its own. I have no doubt it's possible to find a situation in which stacking devices actually does deliver a better result overall but I can't remember finding such a situation when I was playing with this sort of product and I definitely didn't get around to trying every sort of combination of products possible in every sort of way they could be combined. Given the limited amount of information provided by the manufacturers of this sort of product we've usually got very little reliable information to assist us in working out which products might be good in combination so it comes down to trial and error and, given the number of products out there, you can go through a hell of a lot of trials before finding a successful combination and you may never find a successful combination because there's too many possible combinations of products for any single person to try them all. I'm not going to try and stop anyone from trying combining different vibration control products, after all I spent a fair amount of time doing just that over several years. You can have fun playing with this sort of stuff and I learnt a lot from it, even from all of the failures. I learnt a lot about what aspects of the sound I was getting were important to me, what sorts of things about sound I liked and what sort of things I disliked. I became more skilled in listening critically and I learnt things like how much easier it was to make a mistake about whether or not something was an improvement if you were simply focussing on whether you'd reduced a particular problem rather than on what the overall sound quality was. A lot of what I learnt continues to be useful to me in everything to do with system setup when I make changes so I don't regret my time spent experimenting but I didn't find any really beneficial combinations of the products I experimented with. It wasn't wasted time because of what I learnt, but it also didn't produce the kind of outcome I was looking for. YMMV.

Long read but I finally worked up the stamina too carry on through to the end...great post! I agree with most of your points and, incidentally, did wonder about stacking the two D's....don't currently have a second set of Bronze but will experiment at some point in the future...perhaps they are responding in identical modes so stacking may be advantageous...I certainly have no idea about most of this stuff but agree with your summary about simplifying the support structures by using one modality only, one or the other, so not mixing coupling and isolating systems. (as you posted). RE: Clean power for Devialet - David A - 20-Jan-2019 Re stacked Devialet's and Oreas (bear in mind that I have no experience with Oreas, I'm basing my comments on experience combining other devices in stacks): You basically have 2 options: 1- stack the Devialets normally, one on top of the other, and put one set of Oreas between the bottom Devialet and whatever it's sitting on; or 2- as above but add a second set of Oreas between the 2 Devialets. The bottom set should be rated to handle the total mass of both amps, the top set rated to handle the mass of one amp. The main thing you are probably trying to do is to prevent vibration transmission between the amps and the shelf or whatever they're sitting on. Option 1 above works to do that. There's no moving parts in a Devialet so there's going to be little if any vibration produced internally so little vibration transmission between one Devialet and the other. If you get a benefit from the Oreas I think you will find that the biggest benefit will be with them placed between the bottom amp and what it's sitting on. I think you'll find you get a lot less benefit from a set placed between the 2 Devialet's and it may not help at all if there is no vibration transmission from top to bottom Devialet because the Devialet's have little internal vibration to start with. If you want to try it, start with a single set under both amps, live with that for a few days to get used to it, and then try adding the set between the 2 amps. Live with that for a few days also to get used to it and see what you think, and then also try removing the second set and going back to the original setup with only one set of Oreas. See which way you prefer it. I don't think things will be significantly worse with 2 sets of Oreas arranged as in my option 2, but the result may also not be significantly better than your result with a single set of Oreas as in option 1. Since you currently don't have the second set you need if you're going to try it, either borrow a second set to test or make sure you can return the second set if you have to buy them.

The second arrangement with two sets is far better than a single set below the stacked pair. You can see the pix on the Orea thread.

On the advice of Raidho designer, I have made dedicated circuites and changed the aging floor to get a better result and saved a lot of money not buying the isotek) RE: Clean power for Devialet - mmorrison55 - 25-Jan-2019 (25-Jan-2019, 16:51)Alve Wrote:Wow!

RE: Clean power for Devialet - Alve - 25-Jan-2019 Understand your doubt I’m in Russia, things cost differently here the titan was over 3000 euro. Circuit breakers and local wires were 400 euro; 300 euro for the sockets. 1000 euro for the floating floor and the labor here is significantly less than in Europe |
