I ordered an CS4398DAC card from China. Replaced to good quality parts in Powersupply stage. Audio grade capacitors and plenty of power. I wanted to replase the output op-amp stage with transformer stage. Replaced with Lundahl 1690 1:1 transformer. Im really happy with the result and fits my tube rigg really well. Really better sound than my Rega DAC.
