What is your room size?
I own the XA30.8 and I’m pretty sure it would have no problems driving your Dynaudio C1 speakers in the small to medium size room.
It has no issues driving the Martin Logan Montis where the panel impedance could drop under 1ohm. I doubt the Dyns are that unstable.
The amp also pairs amazingly well with XP-12 preamplifier.
