The stock aerco has RCA outs and some have an additional 1/8" out. The maker, jerry I think, can customize with xlr outs I believe. There is a 6+ month wait time on new builds. New they are $750, custom will run you more I would imagine. They hold their value well and sell for $650-$680, as of late. You do have to open up the case to change the batteries and there is no low battery indicator.
