Since the OP likes his amp (just not enough power) the obvious thing to do is to get speakers that are easier to drive! If you want good sound, don't make your amplifier work hard (or it will make distortions causing the system to sound less detailed and harsher).
Its easy to find a speaker that might be as much as 6db more efficient that won't sacrifice bandwidth or detail. That's the same as increasing the amplifier power by a factor of 4. Think about it.
