moon vs bel canto power amp

I would like to know if someone had the chance to compare both brand, regardless the model.

Could you tell me what is your fisrt choice and for wich reason.

Personnaly i have to make a choice between moon w3 and a pair of bel canto m300 whitout trying it.

thank you
I dunno about the W3 but I'd avoid the M300. It uses IMHO one of the worst ICE modules around. Get a REF1000M or 500M, heck even the REF150S would sound better.
