    Firstly it's been tested, solid state amps and DACs have been subjected to large amounts of vibration whilst output was measured, nothing changed.

    Also if you think about the levels of vibration in an aircraft, and all the solid state electronics controlling the aircraft, if their performance was affected by that vibration it might have serious consequences. Gauges reading wrong and so forth, it would be a known issue in the real world, not just in hi-fi.
    Ahhh, just because you can’t measure it doesn’t mean you can’t hear it, or some people hear it in some systems to be more precise.

    I don’t buy the aircraft analogy, the vibrational noise is low enough to keep the aircraft well within its operational parameters to keep it in the air.

    I do not deny psychoacoustics , but I think most people with decent hearing could hear when I swapped out those 3 bases from under my system components.

    Now, I’ll never convince some people of that on an internet forum but from my experience (and lots of experimentation with vibration control products). Vibration control can make audible improvements and its not just about analogue components. You can spend a lot of money on this stuff and it may make no difference in your system. IMO then you have exceptionally well designed and engineered kit that they have designed to dampen vibrations , or you kit is just not resolving enough, or some folks may just not be sensitive to hear it. I’m not going to debate this anymore than that, this is a subjectivists forum and these things just go circular.

    Let your ears be the judge , but you should be able to repeat hearing these improvements.

    If you want bang for your buck FO.q dampening tape ta32 and ta102 a pack of each about £40 a pack from japan. Extremely versatile in what you can do with it, if you just want to try 1 go for the thinner one its much more versatile.

    Indeed but I wouldn't want anyone reading this thread to draw the conclusion that there is in any way a consensus on the matter.

    I was always cynical about such things, although going from a good old black ash MDF MFI rack to a cheap set of Apollo shelves didn’t half make a difference! Mainly in lack of wobble, admittedly...

    Then, a few years back I reviewed an Atacama Equinox Celebration rack with the twin layer isolated glass shelves.

    Let’s just say that rack never went back to Atacama and I’ve since bought two more!

    From what i read, there is very little consensus on most things In audio reproduction apart from possibly in room speaker response where measurements tell you most of the story

    Totally in line with my experience Discopants !

    The EVP's [https://avroomservice.com/evp-2/] are the only product that provided a significant sound improvement [repeatable] to my Sony Hapz1ES...

    These were kindly donated for a "warts and all" review for my facebook group " hi fi tips and tweaks" unfortunately the whims of customs and excise decided that the advice given on there website ie products for review or demonstration purposes are free of duty The Operative with whom I had a very long correspondence over several months said " just because its say so on our website does not mean I can't demand duty from whom I please ".......yes and I am still annoyed 3 years down the line. So to release the items I paid the duty ..therefore I now own them rather than being a group demonstration item ..hay ho. I only say this to put my relationship with the vendor into context.

    If you then marry the EVP's with say a TNT Flexy stand [ http://www.tnt-audio.com/clinica/flexye.html ]
    you will have an equipment stand that will rival many at 10 times the build cost.

    The old "sound organisation" tables (that started it all?) can still be found on eBay for reasonable money, I have some myself and think that they look quite cool. Whether or not they improve the sound is debatable (some would say they adversely affect solid state electronics by putting all the equipment transformers in close proximity).

    Lol - do you *really* think that's why I've got my kit under about 15 levels of Mana?

    Come on... You should know what I'm like by now, mate; I *only* use stuff that genuinely WORKS!

    And I've been using and experimenting with 'foo racks' for well over 20 years... As I've said before, one of the reasons my system sounds so good is because of the dedicated mains and what it sits on, including all other aspects of supplying the system with the correct 'infrastructure', and the huge attention to detail I've paid in that respect to those areas.

    Or I'd hope also any consensus or implication that those who, from years of experience, *know* that well-designed equipment racks make a considerable difference to the sonic performance of the partnering equipment, are somehow 'imagining' the effect

    My turntable sits on an extension to a brick fireplace, and the electronics sit on either a wall-mounted shelf or on a record storage unit.

    What does that Concorde 'DJ' cartridge sound like, Barry, and what on earth possessed you to buy it?

    Love the Revox CDP. Looks like it was used for broadcast purposes.
