I don't know about DK amps but I'm sure you can't go wrong with the Boulders. Try them if yo can...
DK Design Group vs. Boulder
Has anyone here compared DK amps with Boulder amps? I am currently using the Wilson Watt Puppy 7s with the DK VS-1 Signature with great results but I have been thinking of switching to the Boulder 1050 monoblocks and the 1010 Preamp. Will this be a meaningful upgrade worth the extra costs? Or should I leave well enough alone?
