Hi - I got ~$600 for the pair of EV ZX1As which will almost half pay for a pair of the new ones. I will use whatever speakers often (like once a week), but the times I *need* battery-only operation is probably more like 10x per year, roughly. I have a feeling I'll find other uses once I have them, as well.

The idea of Bluetooth won't apply in my case, as I'm always doing live music, and the Bluetooth delay (latency) doesn't work with live music. But I can see using the BT option now and then, for break music, or for when I do events other than my live-playing type events . . .

Thanks for the various ideas/comments/topics ... interesting discussion! -Jim
