Berning ZH-270 Replacement

Hi

Many thanks for all those who have responded so far, some very valuable feedback for which I am grateful.

I would however appreciate if this thread does not continue to get off track into a debate about if the Berning is or is not an OTL design, that is not the question I asked or even remotely wish to have debated.

I would like to get back on track and hear of peoples experiences with the Berning and other integrateds they may have heard/tried and consider recommendations opinions on sonic abilities etc of them all.

Thanks
FF

You're correct Bpinder.

One need only search the archives to find Ralph's detailed and comprehensive explanation concerning the Berning and why it is not a true OTL.

Or email him directly.

Bpinder, just a FWIW, This topic comes up again and again, and every time I wind up with a bunch of messages about the thread in my email box. I try not to respond unless there is just plain and simply misleading or outright false 'information'. That will cause a response, simply to set things straight.

In this case, my company was mentioned specifically in conjunction with false statements about our products.

Ralph, A basic principal of Futterman tube amps is they use banks of tubes in a series, agreed? Atmasphere amps do likewise yet you claim the Atmasphere are not derived from Futterman. Tweaked and much improved, yes and kudos to you for that!

Not fully understanding the highly advanced Berning design is something that you cannot be blamed for. However, to call it a non OTL design is absolutely mistaken and incorrect. The ZH is DC coupled for crying out loud! The DC to DC converters are NOT transformers, their role is for matching impedance in accordance to load. But you should know this already, as this has been explained on the threads and elsewhere time and time again.

Barry, how much power do you need to drive the Sonus? What is the impedance of the speaker like?
