Hi Richard,
I see that you have several Bernings. I am considering a used Berning EA-230 and was wondering what you think of it espeically when compared with the ZH-270? I used high efficiency Field Coil Speakers (Feastrex D9e). These have a 16ohm impedance though. Your thoughts and comments are most appreciated. BTW, I also have a Galibier Gavia.
