@clearthinker I don’t intend to debate what you are saying. But what you are saying doesn’t apply to my specific situation. The amp I have and the DAC I bought are meant to go together. You can say it was "mandatory" to buy the dac. There’s an optical cable that does not carry audio signal, that cable connects the dac to the amp to unlock a current-injection function and allow the amp to perform optimally the way it was designed.
Please disregard my basic stock cable, I’m awaiting delivery of a better one =P
