Hi, as WHF did the tests of both 851N & Nac-N272 recently, I wonder how they comapre when connected to ATC SCM50 ASLT active speakers that I have. I already own 851D, N, E and I am thinking about Nac-N272 + XPS DR as alternative upgrade. Which option will be the best? Understanding that Naim is one-box solution, where with CA we have several "flagship" units, one for streaming, one as dac, one as analog amp all with xlr balanced outputs connected to each other and to ATC. Thanks.
