Hi new here, I read a lot of good and interesting blogs and reviews about GUSTARD X20U DAC, Have a question, it has 2 x ESS Technology ES9018 Sabre Reference 32 bit Dac chip
There are new chips out now the top of the line one is the flagship , ESS Technology professional series ES9038 PRO Sabre series. It has a dynamic range 0f 140 db.
Can the chip be swapped out and the new chip put in for upgrade tweak, or does it have to be done at the factory. ?
