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

Of course. If isolation were possible, we wouldn't even be talking about it.

Now you tell us!
Theaudiotweak is correct, but as I don't have absolute hearing its not too important.
If isolation didn't exist would man have to create it? One wonders, did 50,000 audiophiles get hoodwinked into purchasing isolation devices since the advent of Seismic Sink and Vibraplane 20 years ago? That would be one big honking scam.
FWIW, I received my 4 BC Kones today and put them under my
EE Advant 8 tube pre that AC's had done little or nothing for.
Wham-Oh slamo, good jump on what was already a very good sound.
