The DNA-2 Revision A amp is a beautiful sounding amp and I too intend to keep it for quite some time.
The previous owner of the DNA-2 Rev A replaced it with a DNA 0.5 Rev A Gold because his Vandersteen Model 5s have active woofers and he didn't need the added poundage nor powerage of the DNA-2 Rev A.
As I recall, he stated that sonics of the 0.5 Rev Gold and the DNA-2 Rev. A were near identical, except that there was a bit more weighted presentation with the DNA-2 Rev A because of the power differences.
-IMO
