Has anyone heard a DNA-1 with the Gravity Base upgrade?

@willhifi  Thanks for your update -- I'm very happy with mine, too, and surprised we haven't heard more about them on Agon.  Hopefully, the word will get out eventually!

Thanks @jaker — I went ahead with the mod, and I agree!

Sorry I didn't see this question earlier. I had my DNA-1's updated by Steve last summer and got one of the first base system installations. It, is, frankly, as big a positive surprise as his VRE preamp was when I bought it years ago. I've yet to hear an amp that sounds as good. Sound emerges from a dead quiet, black background and is dynamic and revealing, yet warm and musically engaging.

From the absence of replies, it looks like you're not the only one.  C'mon, Goners, nobody's heard one of these yet?  Crickets...

Sorry, my bad.  I am unaware of this offering by McCormack.

@br3098 thanks for your response; I didn't realize I was unclear.  I was referring to McCormack Audio's Gravity Base System upgrade, which involves taking apart the amp and integrating the electronics with a brass base in a specific way.  I had never heard of the Pillartech approach, but from their website it appears to be just a more rigid rack on which to place the amp.

McCormack DNA-1 or (better) DNA-1 Plus - yes

Pillartech Gravity Base - why?  Do you really think it's going to make a substantial difference?

My advice: buy a nice piece of end-grain maple butcher block to fit under the amp and use the rest of the budget to buy a ton of LPs or a lifetime subscription to the streaming service of your choice.
