Aragon makes awesome amps, as well as Krell and Meridian. If your looking for a serious change in sound, I'd consider DSP speakers or different analog speakers.

There is no really right or wrong match to the preamp unless one was wildly out of the norm. If anything it's of a match of speakers and amps more so than preamps and amps.

If you think listening to music is fun, try learning an instrument.
