Here's another option you might consider that should have no problem driving your speakers. Not tubes, but SS Class A that does a nice job blending virtues of both tubes and SS. Read the reviews.

I've heard Ralph from Atmasphere say that you don't want to push tube amps to the higher end of their output range as their sound quality begins to suffer, so you may want to consider that as you search for an appropriate tube amp.
Best of luck in your search.
