You have great speakers! The Bryston....well.......as long as you don't compare it to anything else it is nice; but there are products outthere that can deliver the emotion and musician intent in the music! The best solid state amps that I have heard are Pass Labs, Odyssey, and McCormack (in order from most to least expensive).
Of course, tubes are a whole different ball game!!! Tubes do realism like no solid state device can do! To answer your initial question - amps impact more than speakers.
