i have not heard the Onkyo line, but i have heard the Hk, Yammy, and Denon line. IMO the yamahas and HK's sounded the same.
I own the hk 525 and although the triple bass managment is nice, i would much rather have YPAO and upconversion (which is available on yamaha 1400/2400)
Reasons why quadruple bass management is not that useful-
Most center channels(including vp150) do not dip below 80hz. A crossover wont be useful since it has a built in crossover

Bass is not sent in high quantities to the surrounds. Last time i checked surrounds were only good for producing rain and wind(rant-been dissapointed lately with amount of surround sound on my dvds). Anyways, since bass is not sent in high quantities to the surrounds, why bother having a crossover?
