Disclaimer: I am a dealer for Pass and Proac, however if you like Totem speakers why not go right to Proac. Similar look, sound better (I find Proac's more transparent and dyamic though) similar price and are easily driven with the XA30.5. Email me if you want more info, but I use Proacs and the XA30.5 for my main display and it is magical.
Almost all Proacs can be driven by little as 10 watts or sometimes less.
