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

I am using Signal Cable for my speaker cables and Acoustic Zen Matric Ref. MKll rca's. for interconnects. In the last couple days I have been wondering if it's not the speaker cables.

TVAD,

I agree 110 percent on the cables. The Integrated only accepts Bare Wire and I am gun shy on buying a pair of $$$
Cables and having to cut the termination off. If it comes down to just being a cable issue I would do it in a minute.
I got get a pair of DH Labs and at least try.
Thanks again for your input.

Tvad,
I will do that, I am not familiar with the MAS but will check that out. When I had my last system ( love to change ) I used Harmonix though out. Prior to that I used many others but another I preferred was the HT Pro 9 Plus.
