I'm a new audiophile so please don't get mad at me for asking this dumb questions as people in Facebook are giving me different feedback and I'm very confused.
I currently own a Hiby R6 Pro which I pair with the Sennheiser 660s. I have just ordered a new Drop+ THX AAA 789 yesterday. Is this all I need to have or I definitely need a separate DAC? I thought the R6 Pro already has a built in DAC and don't require anything else, as the 789 is just for the amplification purpose. I have not yet received the 789 yet since I just ordered it yesterday from Amazon but I would like to get some feedback on this.
Thanks in advance.
