Howie, I haven't heard the dCS in my home (any model) so I can't make a fair comparison. The NADAC fed by HQPlayer is very good. My guess is that is very neutral and that the dCS Rossini may have more body, but without having both in my system I couldn't know for sure.
Thanks and I understand your point. I have an MSB and love it for it's "body" and incredibly smooth presentation. I am really interested in the NADAC now that I have "unfortunately" been exposed to HQPlayer and it's incredible abilities with DACs such as the NADAC, etc. Not that I am ready to get rid of my ladder DAC but know that a DAC such as NADAC must be amazing with HQPlayer uspampling to 256DSD. Maybe the answer are two DACS.
