@mayoradamwest… you are so right... any such discussion should begin with the criteria one values most in their sound reproduction.
For me… that is… the utmost in transparency, detail resolution, clarity, soundstage, imaging, and the tone, tenor, texture and timbre of instruments (especially bass texture and resolution), all in which the Legacy Audio Aeris is unmatched – they make a double bass, cello, or piano sound live / real. Though, the Focal 3 certainly comes close, as do the higher end Magico’s, Tannoy’s, Gamuts, and ATC professional monitors.
Other factors, including aesthetics, are of secondary consideration for me. Moreover, I value the capability of the Aeris to correct for the idiosyncrasies of the room.
For others, these attributes may make them sound a bit strident on occasion - they may value a smoother, less resolved sound. The same is true for the Sopra 3, or the Magicos – they may seem too strident at times (too transparent).
As you say… “to each his own.”
