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?

How about listing all the amps you've heard under $20,000 so we can have an idea of what you've compared?
Please list all of the amps under 20K that you have listened to in your home with your present equipment. As it stands all we know is that you like the more expensive DK than the cheaper one. I applaude you for your perserverance in the face of adversity.
Procalc,

Does DK actually give you the newer unit design or just replace the innards of the Reference unit?

Thanks,
