A small floorstander might do the trick too, but so far none have piqued my interest. Any suggestions?-- Living Voice Auditorium sounds to me like your perfect speaker, but they’re way above your budget new http://www.borderpatrol.net/livingvoiceloudspeakers.htm
Another variable is synergy with a given amp and interaction with your room, hence the need to go visit some dealers and just get some initial pointers on viable systems.
Brands/Models I’d recommend to try to hear are the Nola Boxer, various Totems, Harbeth P3-ESR and the ATC SCM11s. All have their attendant compromises, but broadly fit your stated sonic preferences.
Two current listings that catch my eye both happen to be Italian!
