What DAC to use with a Sony XA7ES

I find my XA7ES which is a stock unit is on the heavy side of sound. Meaning I feel I have to much low end and not controlled. Want to get more excitement into this unit. I can use more detail in the mids and less boom on the low end. I want to try a Dac and hoping someone else is using the XA7ES for a transport and what Dac you may be using with good results.
Any help on picking out a Dac would be appreciated.
Thanks,
Dave
