Just upgraded to the DK VS-1 Signature

I just traded in my VS-1 Reference for the VS-1 Signature. There is a $2000 price difference between the two units. I was already in heaven listening to the Reference, however, the Signature definitely takes the performance up to a new level. In a way that I cannot explain there is a certain glow and a certain airiness that is musical in a way that reminds me of single ended tube amplifiers and yet coupled to a rock solid bass foundation that can shake the room with no transient overhang. The high frequencies are also stellar, that seem to extend out to infinity with a pitch black background. In my opinion, and I might start another shark feeding frenzy here, the Signature outperforms every amplifier that I have heard under $20,000 - making it a true breakthrough for the price.

Any other opinions on the new VS-1 Signature?
