B&W 803D3 vs Avalon Opus Ceramique

I’m using a pair of Avalon Opus Ceramique speaker, and I have test a B&W 803D3 recently, it sound very nice. My questions are:

1) Will you consider these two speakers is in same level? 

2) Also do you think B& W 803D3 is more difficult to drive than Opus Ceramique?  I’m interested to change my Avalon to 803D3 but worrying if my amp can handle it well.  I’m using Electrocompaniet AW-180 mono-block, my amp drive my Opus very nice. THX!
