I'm looking to buy seperates (pre and power). There are a lot of great bass pre's out there so no problem. Power amps on the other hand are somehwhat generic (I know except for class, transient response etc and of course quality). BUT, it's not too hard (or expensive) to get to well over a 1000 watts bridged. At what (or watt) point is it just overkill. It seems to me that it would be better for an amp to be performing in the middle of it's range rather then one that's idling while pumping out 120 db's of sound. I know that bass requires more power then higher frequencies but for the most part you just don't see the kind of power in bass heads as you do in sperate power amps. All things being equal - cab, pre etc - there is certainly a point of overkill on power - but where?
