Hi

Focusrite 2i2 Gen 3 vs Sound Blaster ZxR vs Soundblaster AE-7

Which amp would be better for driving

Beyerdynamic DT770 PRO 250ohms,

HIFIMAN HE4XX and

SENNHEISER HD6XX from the PC?

I have all 3.

The AE-5 offers the best headphone amplifier, better at driving lower Ohm headphones, then the ZxR.
SB-ZxR should give the AE-7 a good run for the money, with higher Ohm headphones.
2i2 would not have as good a DAC chip, or as powerful headphone amplifier, as the AE-7 or ZxR.
