Monosaudio 4Pcs 40x20mm Speaker Isolation Feet Speaker Spike Pads with Non-Slip Rubber Rings for Audio,Speakers, Subwoofers, Home Theater, Turntable DAC Feet Pad (Black Color)

Great quality indeed

They work as expected

I recently bought some new amplifiers, to make rear access easier and to increase airflow around the amps, I wanted additional space above the shelf, and between the amps. I searched for taller feet than what came stock, but about 20mm (3/4”) is where most top out. So I asked if these could be stacked and indeed they can. I bought two sets of four for each amp. This also required me to buy longer screws, but the feet easily accommodated the change. At first I even tried putting the manufacturer’s feet as a third set on the bottom amp (you can see the solid black puck on the very bottom in the second picture), but that made the top amp too high, so I decided on the original plan of two sets for each amp. I used 35mm (1 3/8”) screw lengths for stacking two pucks, and 50mm (2”) for three, my equipment required M4-0.7 machine screws, but you’ll want to match the size and thread for your gear should you decide to stack them. The included screws are stated to be (metric) M4-0.75 x 14mm, as they were too short for my purpose I didn’t try them. The feet work great and space my gear perfectly in the rack, this makes it easier to hookup the many cables in the rear (14 channels between the two amps), the extra space also allows for cooler running equipment which makes it last longer. I find these feet attractive, and an upgrade from the manufacturer’s original aluminum feet (though after I panted those black they also looked better). As it turned out, I probably could have gotten by with one layer of these feet, and the original feet pained back on the bottom, but my end result looks slightly better. So all in all I recommend these feet for single, double, and even triple height configuration. My personal (experienced) opinion is that feet of this type do not affect the sound quality of electronic equipment—like Amps, Receivers, CD/DVD players, etc. I also don’t think the small and fairly dense rubber ring is going to ‘decouple’ a subwoofer from the floor; the original feet or a specialty product like the (much more expensive) SVS SoundPath, will likely do a better job, but every situation and piece of kit is unique. This is an attractive, simple, well made product at a fair price.

Super acabado, le quedaron perfectas al tornamesa

Good quality, solid construction and an excellent replacement for the rubbish feet on my Compact Disc player, DAC and Amp. They came with screws which were unsuitable for the job, but I had a pile of 3M pads that did the trick. Worth every penny.

Nice feet! Solid aluminum, nice rubber o-ring. Installing now. Hopefully the rubber ring doesn’t come out as this ages. These look nicer than what comes on a lot of audio equipment. I’m happy with the purchase.
