For me: I originally started with speakers I liked which had a sound of their own...mainly because I had not learned about system building. I got Celestion SL6sis...and then just bought whatever integrated I could buy...and my source was my boombox with a lineout. That was just out of college. Then I got to amps which I liked...CJ MV60 and bought the accompanying pre without really searching/auditioning seriously. Very happy...just not focused on true system integration/building. fortunately, i never had a system i did not like. I moved to Guarneris and then Strads...and it was at that level i really understood what a difference a system approach makes. That is when i moved away (for the first time) from speakers with their own fantastic sound...to speakers which are much more chameleon-like. I moved to a Wilson X1/Grand Slamm...and kept all my electronics (as below) with the precise voicing i really enjoy...allowing the some what scientific-instrument- like X1s to see their sound thru. And for me, that has proven to what i look for in my speaker at the moment, with perhaps just a designer-added bit of warmth of mid-forward something as a safety net from getting hard. The keys for me specifically are: effortless, effortless, effortless dynamic range (macro and micro) to give the sense of space, a decent facsimile of the scale of 'live' power, full range, pure speed to reflect nuances naturally (not etching/carving out differences which is rarely if ever how one hears it in real life), solidity of frame/lack of vibration and quiet noise floor to keep signal density and purity of tonality high. AT least, that is where i am today. My favourite SOTA speakers for me: XLF, Altair...though i suspect also Arrakis, Genesis 1 series.
