. . . give this very inexpensive effort a shot and judge the benefits in their systems for themselves.Thanks for your report. I've done pretty much the same to my system albeit using different products. (I can't find a UK distributor for Steve Herbelin's stuff and found his US-to-UK shipping costs a little steep for a trial purchase.)
I used a car audio sector, no-longer-made British brand of damping sheets called "Brown Bread" (presumably London rhyming slang for Stone Dead) to dampen sheet-metal casework then, following a tip from Mad Scientist Audio (MSA's Beautox posts here), covered it with 100mm wide, ebay'd, self-adhesive copper (stickyCu) tape which I connected to Gnd. I followed that by making stickyCu'd cardboard covers and shielding for various digital and analogue PCBs.
Next, I tried MSA's "Magic Tubes", a product I've discussed elsewhere (see link). Most recently, I've been experimenting with a bottle of a luridly-coloured, Canadian-made goop called "Anti-Vibration Magic" (AVM), again on digital and analogue PCBs both. (I had prior used dollops of BluTak but have since removed them.) I can recommend both prodcts - for how to use details, see the pertinent web sites.
The improvements were probably as dramatic as yours but they were also galling because I have for years derided those who stress the effect of steps like these. I've now got over that and have been enjoying a very much improved sound at, for the changes I've obtained, modest cost and, strikingly, without changing a single electronic component.
So, yes, an independent though, of course, anecdotal only confirmation of your report.
Whenever I have used tube dampers they always deaden the sound
When I reported a similiar experience to an engineer whose opinion I respect, he suggested that I'd not damped vibration, merely changed its frequencies. Which made sense. I got better results using AVM as described on its web site (though less generously than suggested as I was running out of the stuff). A Magic Tube resting on an MSA "keg" atop the tubes in my DAC's I/V section was also very effective. (Again, see link but go to full thread and scroll down.)
