I'll let someone else with direct experience of these units chime in and answer your question, but you usually don't get replies about Sim products over here and might have a better chance on Canadian forums...
there was a review of the B&W 800 being driven by a Levinson 533h ( using two channels only, 532h below has the same ratings) and the reviewer raved about both components, now the 533h has similar output powers to Sim W-8:
Levinson 532h : clips @350/8ohm, 500@4ohm,660@2ohms
Simaudio W-8: clips @310/8ohm,590@4ohm,1000@2ohm
But the internals are a different story with W-8 having much larger transformers, more capacitance reserves etc.,...
my point being that if the 533h could drive the 800s without a sweat then W-8 should be able to do the same or perhaps better...
I feel you need not worry about this amp being able to drive your speakers, unless your room is as large as a warehouse...
BUT SHOULD RATHER SEE IF YOU LIKE THE SOUNDING OF IT THROUGH YOUR SPEAKERS & ASSOCIATED EQUIPMENT.
here is the link for 533h and the 800s:
