I will add the Sennheiser HD660S (refurbished for 300€) to the current stack:
- Bose QC35
- Beyerdynamic Tyger
- Koss KPH30i
- Sennheiser GSP 300
Because of the addition of HD660S, I would need to add a headphone DAC/AMP combo. The combo would need to have a USB connection (using a KVM).
As mentioned in the title, I’m looking at the ifi Zen DAC or Topping dx3 pro. Both are below 250€ (my limit) here in Europe.
Is there any other option that I can get on German Amazon/EU? Or any of these two options a clear favorite?
I looked at the Fiio K5 pro, but I can’t stand the design, and it’s not on the contender list.
