The truth on low efficiency speakers like B&W?

I've been learning a lot lately, but I'm still questioning the true amp requirements for speakers such as B&W 802s. I've seen mentions of using 45 watt tube amps all the way up to 600 watt mono blocks. Seriously, what is too little and is a 600 watt amp over kill? Can the speakers ever be pushed hard enough to overcome an amp like the Parasound 2250 with 250 watts/ch @ 8ohms and 400 @ 4 ohms? Is heavy bass music require the upper ends of power? Thanks. Owners please chime in with issues you have had with low power amps.

Whatever one's motivation, for better, complete bass at higher volumes, more power will only help and seldom ever hurt with speakers like the B&Ws.

If you only listen at low to moderate volume, you might get away with 40-60 good SS watts.

Tube amps + B&W speakers are not normally an optimal match from a technical perspective TTBOMK though some might still of course like the sound.
