I love my Berning ZH270 Amplifier! The only thing that’s missing is a bit of high treble ‘shimmer’. Any suggestions on who I can contact for upgrades or suggestions for tube choices or other adjustments that can be made to bring out some sparkle at the very top of this amp?
yes, David’s a very nice guy. Even though we’ve become friends he still takes a week to reply to an email from me. He’s is sort of semi retired especially since Mark has really kicked in their production.
Mark is also a good guy to talk to over the phone. I believe he is still out of the country but will be back soon.
