Cardas Clear Cynus vs. Neutral Reference XLR

Does anyone have experience with both of these ICs? I currently use NR between my pre and power amps and wonder if the Clear Cygnus is worth trying out. My system has been stable for a long time and I’m not looking to change the basic tonality. I would like a little better defined transients, such as found in acoustic guitar music. Will the Cygnus give me that or is it a more lateral move?
