Thank you
Yes, to maintain absolute phase with your DAC as the source you would invert the phase on the preamp. As long as the DAC is your only source that's fine, but if you have other sources with non-inverted outputs you'd have to switch the preamp back to non-inverted. Not sure if the C2450 allows you to select phase based on input, but if it does that would allow you to select proper phase specifically for each source you have connected. Another alternative would be if your DAC has a phase inversion switch you could invert its output and then keep the preamp set to non-inverting.
