Practically of course it can be used. No technical incompatibility. Why not try it since you will have it.

But how you will like the Khozmo 10k log + DCG3 combination is for you to judge. Squarewave rise time will be faster and bandwidth will be wider than with a 20-25k log for sure. That can be subjectively interpreted as clean but also as lean if an audio system as a whole lacks warmth. Including your room acoustics.

These are the dimensions:

Dissipation is 10.2W at 150mA +/-17V for two channels. No worse than 1C/W (K/W) sink for 10C rise above ambient should be used. That's in free air and optimally oriented. Expect higher rise when boxed. Ventilation holes should be in vicinity. For mechanical stability & heat transfer the sink should be bolted in touch with the chassis. Apply thermal paste between their meeting metal surfaces. An adequate example sink type:

Fischer SK 85/100/SA
