Anyone familiar with the Matrix Audio mini-i pro

[marioed]

I'm looking for a new dac/headphone amp to use in my office computer setup and was wondering if anyone has any experience with the Matrix Audio mini-i pro, Matrix Audio Mini-i Pro, and what your thoughts are about it. My current setup is a 3rd gen Intel core 7 based computer running Windows 8.1 to a Cambridge Audio DacMagic into Adam A5X monitors. I'm specifically looking for a dac/headphone amp that does dsd and has both balanced & rca outputs. I'd like to keep the price around $500.

Regards,

Ed
