Gary: Congratulations! Sounds like you made a terrific sound quality choice going with the Sona 32C's:

Looking forward to gig feedback & seeing pictures of your new setup in action. I assume you're slimming down your entire setup, including taking out hopefully just one keyboard (PSR2000?) now, right? This way you can send your vocals thru the PSR2000, and then go out directly to the Sona 32's, avoiding the need for an external mixer, to reduce your travel load even more.

Also: I'm curious, what type of carrying handle(s) are 'built in' to the Sona 32's, and how comfortable (ergonomic) it is to carry considering the speaker box is pretty square (angular) vs rounded (JBL Eons & EV SxA100s)?
