All Benchmark System Question

Long time lurker, first time poster. So question relates to my all Benchmark System. I am using the all Benchmark system (AHB2, HPA-4 and DAC 3B with my P3SER’s and loving it most of the time. But if I wanted to add a little more warmth for that 20 percent of the time I think I need to, What would be the best way to do that. My thoughts are maybe switching out the DAC 3B some of the time with an Audio Mirror Troubador, keeping the rest of the system the same. My other, more expensive thought is to leave the DAC 3B and i swapping in the Coda 07x part of the time as I have heard the AHB2 and Coda 07x is a great combination. Obviously that is an expensive fix for 20-30 percent of my listening.
What do you people think?
