The time interval from electro-static Acoustat 1+1s to 4Pis was about 20 years but there is a bellwhether that I can't forget. The first cut on side two of Joni Mitchell's "Blue" features 12 string guitar. The Acoustats present the ringing and decay of the harmonics at the end of phrases far better than the 4Pis, or any other dynamic speaker I've heard. Sounds almost like a Sitar.
OTOH, the 4Pis have greater texture in the bass, image better and, as for dynamics, are unequaled.
