Prepare yourself for the bass ... I believe the 10T's are one of the great "underrated" speakers especially for rock music. I had the pleasure of trying a pair out for a couple weeks ... I have to tell you they like plenty of clean power. I first powered them with a Nak PA7 and then plugged them into an old Pioneer Spec system (Spec 2 @ 250 WPC). It was pretty amazing... I finally hooked them into a Denon 5803A receiver and thought they lost a lot of their magic.
Not bad mind you, but matched with the PA7 put the 10T's in a whole different league. I'm not sure what you looking for in terms of sound, how big your room is or what your music preferences are but I think the Classe 301 will be stellar. It will almost be better to run them on a receiver first as it will give you a good contrast when you bring the Classe into the mix.
Curious what pre are you planning on using?
