Any plugs even non-shorting plugs like Cardas Caps etc. that are inserted into unused inputs or outputs will improve the sound and make it more 3 dimensional.
The effect of the Silent Plugs is far beyond that of other vibration and rfi plugs and devices. Far beyond.
You said far beyond twice. Would you say the plugs doubled the performance? What other vibration and RFI plugs are you referring to? Not all others, one assumes.
Acoustic Revive, Cardas cap, and although not promoted as RFI/Vibration device, the digit (?) plug made by the Belts
Had you tried another RCA plug device that was to be put in unused RCA jacks that has/had both RFI/EMI and vibration damping? I wasn't aware of another on the market. I have Cardas caps that do not help much if any. I'd like to try a set or DIY clone them.
Acoustic Revive (don't know the model)---a friend had several pair. While I could hear an improvement, I would not break out the credit card for these. My experience w/the Cardas caps mirrors yours. They became a set of cat toys for a brief spell before the cats batted them into cat toy heaven. Good luck on DIY. I have no idea what the damping material is. They rx'ed a positive review in 6moons which gave a fairly good description of the construction and also had an interview with the designer who may have mentioned the damping material. I'm no techie, so I don't recall. Also I don't know if the silent plugs shield from RFI. They're not metal, so... Keep us posted on your DIY experiments. It would be great to have another method of reducing vibrations.
I find Herbie's Audio Lab HAL-O JR. Interconnect Damping Instruments to be potentially effective devices to reduce interconnect cable borne vibrations. However, I also find the curious affectation to be quite cable/application dependent, so YMMV. See link:
I have tried the Herbie's IC dampers....but I got the Titanium ring models and not the ones Duster showed (nylon ring) in his picture.
I did not like them. They made a change just like the pads on them...soft, squishy, took some of the life out of the music.
But good thing is Steve (Herbie's) does offer a refund if you do not like his products.
It's a cable/connector sensitive device, so I'm not surprised -- it hasn't been a good thing for a number of my cables, too...
I made my DIY HALO's from some screw-in teacup holders and silicone round discs I found at Target. I used some side-cutters to cut the half-round teacup rings to a sharp point, then just pushed the circular discs through in the middle. The silicone discs come in various sizes, so you can custom them to your needs. You can trim the portion that fits against the RCA connection to make a perfect fit. The silicone discs are not too squishy and definitely made a small, but clearly audible improvement in my system. In places where too many cables did not allow for the DIY HALO's, I cut some square silicone pads I found in the same section, in a diagonal, forming two wedges and simply fit them between the closely placed connectors with the same effect. Every little bit helps, especially when it's cheap.
Thanks, Duster. I'll give these a try. I have several types of Herbie's feet and pads in my system; I find them very effective. I overlooked these.
I just scanned the 6moons review again and the plugs are made of aluminum, so they may have some RFI shielding effect. And no mention is made of the type of damping material (other than "special damping material).
Also the Acoustic revive plugs came with a sheet of damping material that one could apply to the back of the plugs if one wished for more damping.
