OP can try better music server or CD transport.
The law of diminishing return is stiff for Dac.
I have been using EMMLab Dac2(paid 9K$ for new one) for 9 years.
It is time to upgrade but no easy choice under 20K$..
Also it is possible that some innovative Dac can come out in a year or two at reasonable price which may crush all existing Dacs.
