Amps and speakers should always be considered as synergistic pairs, in my experience. It is entirely the luck of the draw if you don't make one contingent on the other. So, if you're going to start by just buying what you think will be a great amp, be sure you consider which speakers it will match best with and be sure those speakers would fall within your universe of great speakers to own.
I much prefer to start at the other end of this equation and select my speaker, and then search for the amp that will be the great match to will bring out the best capabilities of that speaker.
