DCS Bartok vs Jeff Rowland Aeris Dac


My current system is all Jeff Rowland equipment, 925 Amps and Corus preamp including the Aeris Dac being powered by the Jeff Rowland PSU. I have a feeling that my Aeris DAc is the weak link in the system. Has anyone replaced or added the DCS  Bartok Dac to  a Jeff Rowland system and if so, was it an improvement? Love to hear your thoughts.
