is my system set up correctly?

Hi all-

I have a Creek Evolution 50a and a Creek Evolution 50D cd/Dac.

I recently read this on Creek's website:

"Excellent measured and sonic performance has been achieved with this analogue integrated amp, but when using digital input signals via the matching EVOLUTION 50CD, the analogue pre-amp can be bypassed completely. The EVOLUTION 50CD has a very high-end volume control in the digital domain and ‘Class-A’ balanced audio outputs. Connecting the output directly to the 'Power amp direct' inputs elevates the performance to an even higher level."

I can't figure out what this means! I have a pair of Analysis Plus RCA interconnects running between CD player and amp on line 2. Should I be doing something differently?

Thanks!
Margot
