Cdente,
I don't have Joseph's DAC, but I'm going to assume that the Claritycap will raise the level of quality of sound just as it does in the preamp. Joseph would be better qualified in telling you if one or all caps should be changed out to Claritycaps. If you want to see if the AH preamp would synergize better with your DAC than your Bel Canto, try out the AH preamp yourself in your own system with their return money-back guarantee. If you like the AH preamp the best, I would imagine that you could resell your Bel Canto on Audiogon for a reasonable price. Maybe someone that currently owns the AH preamp who might have previously owned the Bel Canto pre can chime in to give you some first hand experience advice.
