Meitner DCC2

I have asked this question in another thread but would appreciate more feedback if any.

That CDSD-DCC2 is great is not much in doubt. My question is with regards to DCC2's pre-map funcationality and specifically its quality.

Would u recommend hooking it up directly to power amps, thus suing its pre-amp funcationality, or by passing and thus using a separate quality pre-amp? If so any in particular? I have Linn Klimaxx 500 Monoblocks.
