More open sound-NAD C542 or Mus Hall CD25.2??

I have Silverline Audio SR12 and the new NAD C455BEE and
im looking for a cdp. Im deciding between the Music Hall
and NAD...which one would be more open, airy and detailed??
I have the CD 25.2 with upgraded op-amps and couldn't be happier. It has all the attributes you want, which became significantly better after some basic acoustic treatment (foam for now) behind the speakers.
