Snofun, clearly the reviewer says that based on the performance and the build of the amplifier, "I figured I was listening to an amplifier that would retail somewhere between $5000 and $7000". So, what is your beef? This is definitely an outstanding complement to the DK.
I am also surprised that no one brought this up yet, but there is actually a mistake in the review. The reviewer states that Siemens NOS tubes were used in the DK during the HE2005 show where he heard it first and thought so highly of it. But, the tubes that were used in the DK during the show and driving Von Schweikert speakers were the Mullard Cryo CV2492.
I actually tried the Siemens NOS in my DK VS-1 Mk. 3 and did not like them very much. But the Mullard CV2492 did make a phenominal difference in sound quality.
Despite all this commotion about the DK, I have never talked to anyone who actually heard the unit or owned it that did not enjoy their time with it; I wish the same could be said about Krell, Levinson, and a few other brands that appear in Snofun's system...
