It's been two days since I bought the smsl sp200 amp for my akg k712 + sennheiser gsp500 and I paired it with my ifi zen dac by the rca output. My problem is that during my listening to the test I noticed that the treble and bass are more detailed on the zen dac headphone output compared to the sp200, at the same time the output of sp200 is cleaner with good separation of the instruments and more power.
-1) is it normal that the ifi zen is more detailed on the treble and bass than the sp200?
-2) is zen dac not the ideal solution to power the sp200?
-3) does the smsl sp200 amp require a burn-in ?
-4) do I have to change the Zen dac with a better dac like topping d50s to take advantage of the performance of the sp200 amp?
