Never look at the specs and for sure you will wind up doing it by trial and error. Get on target first with objective parameters, then you can start with the audiophile approved "search for synergy". The last part is the crux of subjective audiophilia: the match you make may or may not have widespread audiophile approval (ask three audiophiles about anything and you will get five different opinions) that's ok so long as the sound pleases you.
