My Krell which is a class a/b amp runs class a for 50w and my Vandersteens are 86db/1 w. Not being a headbanger with the volume control and with the size of my room I don't believe the amp has ever run above that point. I like the Pass Aleph 5 class a at 60w and those are below $2000 and should work great with your Dalis.
