25 watts of tube Luxman current is substantial enough for most speakers. I would pay attention to db efficiency, but not live by it alone. Take the amp with you to demo speakers if necessary, I'm sure it will suprise you.
I've a Sugden 30wpc class A amp that drives silly anything I've hooked up to it.
