JTINN will tell you that I told him the same thing with my DCC2 and NAGRA PL-L tube preamp.
That is until I let the DCC2 break in and got the CDSD.
I agree that tubes gave slightly more of that "air" but at the expense of pure transparency,detail and precision.
After A-B'ing many times it was clear to me that I preferred the accuracy of the DCC2 and was happy to recently cash in on my NAGRA & xtra VALHALLA IC.
