The Scintilla 1 ohm stands alone. It has benefited the most through the use of new ICE amps. Bel Canto can't do Scintillas. t least one member I know of has sold his Evo Gen II amps in favor of H2O amps.
Divas, Duettas, and Calipers are the other big Apogees. I know I left out the Full Range. It is a special case, and is the rarest.
The Kapton backed ribbon speakers have a more in your face presetation. At 4 ohms, they are relatively easy to power. All three sound splendid, loosing just that last bit of resolution the Scintilla affords. Their bass panels go deep, and are very fast, allowing wickedly quick articulation of deep bass notes.
