Rcprince is right. With a piece that expensive, you should work through a dealer who will loan one to you. If you are planning on buying used, then you will have to pony up the $$, but you should not loose much if anything with a piece with the rep of Boulder if you decide its not for you.
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?
