I have been mulling mono blocks over my current class D amp as winter creeps in and my basement listening room requires some heat.
The JC5 - an amplifier that is engineered as "dual mono" but can be bridged to feed one speaker seems a bit redundant to me. Was it engineered to be a dual mono amp, or engineered to be a dual mono channel amp that secretly sounds better as a mono-block? Nice that it is versatile, but, wait, what? Stymied is what I get out of it. While the topology may just be my issue, the heat one puts out vs. the other would be, I dunno, maybe not even an issue either. But it is most likely that you will love the mono-blocks but they produce enough heat that you consider keeping the JC5 around for the summer months. Hope you can give yourself a monetary buyout in best/worst case scenarios.
My interest in running mono blocks (Schiit Tyr just dropped in price) would be to push (energize) my Wharfedale's that I purchased some months ago. The probability of some added clarity in definition (class D to class A/B) is another selling point.
Considering the quality of your newly purchased B&W's, however, I would have already pulled the trigger on MC mono-blocks if I had recently acquired such a beast. You must be itching to see what they are capable of and I would think that is what you had in mind when you bought them - to mono block them with a vengeance!
