I am by no means an audio gear expert, but I have the O2 amp and HD 6XX (the combination you mentioned). O2 has a headphone jack (to plug in your headphones), a port (for power), and RCA cable inputs. So, the only possible inputs to the amp are RCA audio cables (For Left and Right channels, in white and red). So, how do we connect the music source to the amplifier? One possible way is, use a 3.5mm to 2-Male RCA Adapter cable. But I am not sure if the audio quality will be clear, since music will be amplified but the clarity will be as good (or bad) as the in-built DAC in your laptop/desktop or phone. It makes sense to buy a DAC, from all the sources I have read. You can buy the 3.5 mm to RCA cable for 9$, and check the audio quality (Frankly, I have not checked it too, though I assume it should work). I have ordered a DAC (Topping D10). It is not very expensive, has very good reviews, but delivery takes time. I am still waiting for it. In the meanwhile .. I am using 2 devices as DAC. End-to-end connections: (1) Laptop (source) -- > Centrance DACport HD (DAC) --> Objective 2 (Amp)--> Headphones (Senn HD 6xx) Apple Mac --> Centrance's USB 'slot' =Centrance= Headphones 'slot' ---> 3.5mm 2-Male RCA Adapter cable to the Objective 2 amplifier --> Headphones. (1) DAP (source and DAC) --> Objective 2 (Amp)--> Headphones (Senn HD 6xx) Shanling M0 (Headphones slot) ---> 3.5mm to 2-Male RCA Adapter cable --- > Objective 2 amplifier --> Headphones. The DAP acts as a DAC since it has a very good DAC chip. I connect HD 6xx directly to it too. It works great (as loud as I can handle, and very clear). I almost don't need an amp.
