Can I go wrong with Stillpoint Ultra Mini anti-vibration isolation feet?

@skyscraper yes it's just like choosing cables,it's all personal taste.I tried the roller blocks under every component,couldn't hear a difference at all though I expected to.Regarding the air pods mentioned above,I haven't tried them - but I've got an air platform under an ss integrated amp in another room which I like,tightened up the sound.Under tubes components it was awful!
What I personally like(which you may not) are sand boxes.The Dac sits on a ceramic tile, on a sandbox,on Orea mini pucks.The pre is on Orea pucks and then the sandbox.The amp is on IsoAcoustic Aperta200 speaker stands.I actually bought those to use for my speakers but once again,didn't like the sound.I like a spruce board under the speakers.All of my components are tubed.

I guess my point is to think about trying many things before spending $$.Corks,marbles,metal screws,bricks,mouse pads,dishes from the kitchen,sponges,etc.It gives you an idea if a springy footer is what you might like or something firm or spiked.Before I went with sand platforms I filled a plastic storage container with sand just to try.The sound was really night and day,so then I could move on to something more aesthetically pleasing.

@select-hifi,

Spoken like a good salesman. Not that I disagree. ,,(I own a Rock 7).

I think like most of us audiophiles, we strive for more. We've heard things...and we like it.

@fsonicsmith ,

May I ask the total weight of your TT that the Minis were supporting? They are rated @10lbs .each. I have a feeling that you overloaded the Minis.

As fate would have it the best AND most cost effective way to get outstanding iso performance in all or almost all directions of motion is by combining roller bearings of sufficiently good design with simple springs of appropriate design. The springs afford excellent isolation in the vertical direction 🔝 - probably the most critical direction - and roller bearings in cups afford excellent isolation in the horizontal plane 🔛 (infinite number of directions, no?) PLUS twist, rock and roll rotational directions. 🔄 Problem solved! 🤗

For the advanced student try a double layer mass-on-spring system for extremely low resonant frequency.

I use townshend speaker bars under my speaker stands and they make a big difference to imaging.

I have stillpoint ultra ss under my down firing sub, makes a big difference to the sub performance.

I also have black ravioli mk 2 big pads under my isotek sigmas mk2 power conditioner, again big difference to imaging and much more relaxed presentation. Beware though that I had to wait a week for the sound to settle and on day one and 2 the sound was muddy.

For my ss amp, ( Lyngdorf TDAI3400), and my Etheregen network switch I have black ravioli mk1 pads a stack of 2 plus and oak cone for eack footer (4 footers on the amp 3 on the switch). Tighter soundstage but less of an improvement than speakers and power conditioner.

Apple TV just has 3 black ravioli mk1 pads and I weight the top of the unit. Improvements as above.

All my isolation above equipment bought 2nd hand at 30% to 60% retail.

Buying 2nd hand let’s you try and you can move on for minimal loss.

I would like to try the stillpoint minis under my amp at some time but it’s not a priority.

If you want ultimate vibration control bang for your buck, I would reccomend getting some fo.q ta32 and ta102 from eBay Japan and research using it throughout your system including power outlet plates, cabling, equipment chassis (especially near iec inlet), speakers cabinetry and drivers including stands), pcb and electrolytic capacitors(careful it is conductive).

I had a pack of each so far I want to get another pack of each as it is incredibly versatile if you are careful and not concerned with warranty of your equipment you can really deliver much more SQ than what you could achieve with 1 set of stillpoint minis. If you are concerned with warranty then you can still achieve much on external chassis, cabinetry, plugs, cabling and sockets. It is adhesive but its very easy to use and remove.

Fo.q and oak cones may make a very cost effective footer option too.

Good luck with your vibration control journey.
