The Yamaha and Onkyo receivers are generally brighter sounding and have turned more toward the marketing hype sceme. H/K maintains their integrity by continuously underated their amplifiers and just as well they have a warmer sound character to them.
HK simply plays it differently, by turning to other hype such as specifying high instantaneous currents such as 70A, without telling whether that is the total of all 7 channels driven to maximum, or for how long, like microseconds, mini seconds etc. They also specify their "maximum Power consumption", e.g. 890W for a 335 at the specification section (page 54) of the manual while specifying their power consumption (they call it AC input) at the rear panel (see page 7) of only 370W, that is in line with similarly priced receivers from Denon, Yamaha, even Sony etc., again without specifying under what condition.
So I agree with Nick, Yamaha, Denon or HK at the same price point will not sound much different. Example, I listened to HK, Denon, Yamah and others, they sounded just as bright (or detailed) to me. IMHO you are safe to just go for the one with the features you want and the look you like most.
