McCormack DNA 500

This amp is at the top of my (very) short list for a near-future amp upgrade, so I am very interested in the responses to this thread, not only by those who have read the reviews, but by those who have actually heard (or preferrably owned) one. I did notice the Kraft and Moncrieff reviews referenced a slight lack of focus in the HF, that wasn't mentioned in the 6Moons or Jim Merod Onsoundandmusic reviews. Can anyone shed light on what would seem a deficiency? I liked Chip Stern's 6Moons review the best because of the interview with Steve McCormack, and because I thought the article was well done. Other amps I am looking at in the price range include the SimAudio W6 monos, and the Belles 150A Reference monos (see gushing review by Doug Blackburn in Soundstage).

I have owned a stock DNA-2, DNA-500, Signature DNA-2, and a totally rebuilt TLC-1 Signature preamp that is very, very, close to the SMc Audio VRE-1.  That preamp is outstanding and bettered about 20 others I previously owned.

I am currently awaiting a pair of Steve's new top-of-the-line SMc Audio DNA-1 Ultra G Monoblocks with the new Gravity Base System.  I have also owned several other highly regarded Class A, D, and AB amplifiers but none I was quite ready to consider my end game (although the Clayton M300s I have owned twice were very close).  I can't wait to hear these new SMc amplifiers - they are supposed to be here on Monday.
