Isolation feet/cones for PS Audio NuWave DSD DAC

Believe it or not the paper label should be removed from any and all DH Cones as it degrades the sound a smidgen. It has to do with the whole idea that the interface needs to be very hard. The only exception I can think of are DH Squares, which are not particularly hard in the extreme sense of the word.

Thanks again for the tip, Geoff. This makes me think that adhesive might not be such a great idea either. I suppose some adhesives might work better than others. The only reason I thought of it actually was that it should make  it easier to ensure the cones stay in place when trying to get them under the amp.

@agriculturist the adhesive is a huge no-no. You want to avoid anything that will introduce another interface between your footer and the amp. Some sort of squishy gluey stuff will just reduce the effectiveness of the coupling amp to footer. Many manufacturers make add on footers with threads that you can swap for the OEM feet but I don't think this is necessary. If you follow the setup method I recommended and/or use some shim blocks as @lak suggested you should be fine. I actually went so far as to buy some low jacks to assist when I needed to swap the feet under my amps stand while leaving the amps in situ -- something like this may make your job easier (although they have a minimum height of 4.75" which is still pretty high)

OK got it thank you @folkfreak.  Very good to know.  The super jumbo Golden Sound cones are 1.5 inches so these jacks might be to too tall.  But I now have some good working ideas from all your advice how to go about doing what I need.  Thank you!

Thanks a lot for the help @folkfreak and @lak.  I got a pair of 2 inch high stainless steel block shims from Amazon and that worked like a charm to get the GS cones under my amp.  

@geoffkait, since you are quite familiar with the Golden Sound cones, another question for you please.  Are the super jumbo cones OK or even better than the smaller GS cones for less heavy components such as a DAC which weighs say 20-30 lbs?  I have a second set of these super jumbos on their way to me and I wonder whether I should put them under the DAC or under my pair of stacked BPT balanced power conditioning/isolation units.  I am wondering whether I would be better off with one of the smaller cones for the DAC.

Thanks again.
