so it's just better technology giving the perception of 'sweetness/ warmth' (emotional engagement?) rather than a deliberate aim to do so. I find my older bryston to be consistently 'neutral', clear and clean, but never 'sweet/ warm' (highly emotionally moving at first listen) in the way some other (fuzzier sounding) amps are. I'm not sure whether that 'warmth' will be communicated via my PMC MB2 speakers though; whenever I've tried such gear on them (audio note, myryad, couple others), they sound excessively smooth, dark and very bland instead of sweet. If it does work on the PMC's, I think I'd want to buy one; such gear is easier to listen to during casual listening and entertaining, not to mention the increase in ease and dynamic impact at normal volumes.
Btw what time is it where you are James? ( bryston would be a lost cause without you; I hope you have equity in the company; if not, they'd better give you some!)
