I have a Pace Car 2. Adding it to my system resulted in better perceived resolution, improved imaging focus, less shrillness in high frequencies, and a lower noise floor. I wrote a review of the Pace Car if you would like to know more about my experiences with it.
I have not heard the dac's you are considering so I cannot advise about which change would result in greater improvement.
Good luck.
