If you already did so good work with design of PCB, I would suggest you to consider of using a free convection type heatsinks instead of forced air one, and to orient them properly.

Also, capacitors in close proximity with heatsinks is not a good idea.

I hope it helps to improve your kit!

My newest project will be the overkill and a need more time from the idea to the listening enjoying (see the other thread)...
