All aspects are important,however;I feel that a pleasing tonality is the key ingrediant.I can't consider the "soundstage" or "air" if I cannot get past a harsh treble or lifeless midrange.Remember that this "tonality" can change drastically with different ancillary equipment(amps,preamps,DACs,and cables)and room placement.Speakers must be auditioned in the context of a specific system (where a synergy is achieved) and in a specific room placement.
Speakers: What's MOST important to you?...
When you demo a pair of speakers, what criteria do you use to judge the quality of sound? What must the speaker have or do that will bring out the check book or credit card?
