Mike, I once owned the Innersound Eros MK II and I agree with you concerning the sweet spot ---- way too small. On the other hand, the sound they produced was exceptional. I've gone from the Eros to Von Schweikert VR4 Gen III's, Meadowlark Osprey's, Source Technology and others ----- all good speakers but none of the 'cone' speakers captured the magic of the Eros.
I sold my Von Schweikert's to a fellow Audiogoner who also owned a pair of Martin Logans --- he had the Von Schweikerts up for sale and sold within a month.
I am currently waiting for a demo of the Eminent Technology VIIIa's.
When going form an electrostat to a cone speaker, I would make darn sure you listen to all of them at length (if possible) before you commit to purchase.
Best of Luck
