Best isolation cones


Wanting to purchase some new isolation cones for my amp and Oppo 105. See Nordost isolation cones however wondered if they are really worth the extra money or are there any alternatives? One of the things I don't like about Nordost cost is how high they make your unit sit. Also I have seen other isolation components like Vibrapods or Pangea audio Mega feet at a fraction of the price.

Advice please

Thanks

No question about it, the NASA grade ceramic Super DH (diamond Hardness) Cones from Golden Sound.
I placed some of the Nordost Sort Kone TC under an Art Audio Vinyl One phono preamp and they made an easily audible improvement.
You need to try a bunch of different cones. They don't all sound the same. Sometimes you get lucky and they don't make any difference at all.

Regardless, I use Cable Company for this. They sent me a whole assortment of cones to try first. I ended up liking Polycrystal and DH cones the best.
I am using herbies tenderfeet on my OPPO 105.
Cardas wood blocks were a disaster (sympathetic resonance with the drive went out of control), therefore I would tend to recommend against solid supports like cones. I removed the OPPO feet and placed the 4 tenderfeet in the vacated locations. If you dont like them, herbie has a 90 day return guarantee.
For those who recognize that isolation will only exist in the absense of matter the same people may also recognize the products and methods described above only change the material Q of the chassis placed on top of the so called isolation device. Pick your color or flavor of the day, add your spice or take it away. Isolation if it were possible would have no descriptive adjective attached.Tom
