cones under your tube amps??

Personally, I prefer to isolate my tube preamps from inco ing vibrations as opposed to coupling them to the floor with cones/points, which I do not believe, despite propaganda to the contrary, isolate anything by themselves. FWIW my amps are SF SFM 160's.

Yes, it's worth experimenting with cones. The results can
very by product but the potential for improvement is significant Particularly good cones can be found at the
Mapleshade web site.

Hi Klk,

Please be aware that pointed cones are rigid devices and will not isolate your amp from floor-borne vibrations generated by the speakers. In addition, using only three pointed cones will leave two of the corners of the amp unsupported thereby allowing them to be more easily excited by air-borne vibration.

Rolling ball type of devices are also rigid in the vertical plane and will allow floor-borne vibration to be a factor.

Both pointed cones and rolling balls do not address air-borne or internally generated vibration so at best, they can only be partially effective.

I am not a manufacturer,just a Starsound dealer..Before I became a dealer I had a buddy who was looking for a new amp to replace his Conrad Johnson that was driving his Thiels. I lent him a Sistrum Sp1 to put under his Conrad,he thanked me and told me the improvement was so great it was like having a new amp..It's been 3 years since he purchased the Sistrum Sp1 and he still has the Conrad amp..Oh he later bought a pair of Sistrum Sp004's to put under his Thiel's.
