Whether he did or not (honestly, I am not sure whether his last post is just saracasm or not), he did bring up a good potential opportunity to further improve the Comet’s sound - vibration control. I tend toward using conductors to transfer vibration to a dissipative interface, so I thought the hard metal bearings on the bottom of the Comet that are direct coupled to the chassis would be ideal, but perhaps improvement is possible through experimentation. I have had great success with Symposium platforms as a dissipate membrane.
Also, since the Comet uses an external power supply, isolation (not rubber!) of vs conductance from the DAC itself might be beneficial. I plan to test these things next.
