Thank you for the reply. I think i will stick with the qudelix and save some money for now. It is good to know that there are no night and day differences.
I just bought my first set of headphones, the Hifiman He400SE and also ordered the qudelix 5k dac/amp.
Since i am very new to the hobby, i am wondering if the topping dx3 pro+ with more power would be a better choice for the headphone?
