[quote user="Merlin"]... my own feeling is that David Berning's solution is both neater and more practical - the only impediment ot it's acceptance, the dogmatic approach of many thermionic die hards. My experience suggests it's their loss. [/quote] ...

An Audio Amplifier Design Philosophy

I became interested in audio at a very young age because I liked music, but was too uncoordinated to be able to p...

Hi Montepilot,Thanks for your thoughts. I'll certainly let you know how I get on high-passing the Druids... with and without sealing the port.Mani....

Well,Berning is a genius to be sure. Here he fixed his sights on the "evil" output transformer. Every part of the circuit alters the sound somehow, of course, and the goal is to find the least damaging topology. The question is aske...

Wow! Paul, I have to say you really hit the nail on the head this time; whereas usually you strike me a bit more obliquely:[quote user="Paul S"]...the Berning ... makes the music happen as oposed to letting it happen...[/quote]This is exactly w...

I was so impressed by the concepts Berning put forward, though Romy correctly points out that it solves some problems whilst creating others. As is always the case, topological change is like a chess game. Anyway I actually bought a Berni...

And I do not mean this as a criticism.I had for some time an "original" Music Reference RM9, which was made by another well-educated genius, Roger Modjeski. The RM9 was AB PP with adjustable bias and feedback/gain, with 6DJ8 drivers and a ...

Welcome to the club:"Debuting the new Quadrate Z, David Berning was displaying a new amplifier designed to output 200 watts per channel. The design is comprised totally of tubes and incorporates ZOTL technology. The amplifier retails for $29,900."...

[quote user="manisandher"] Do you think 150Hz is too low with a 7W SET?
In all honesty, I think I was heavily influenced by the Zu Druid 'hype' myself. I had bought the Berning (without really thinking too much, really - it seemed like a good ...

Meriln, this is one of the subjects that disturbs me in your description: your bring OTL consciousness to justify Berning and you bring all those foolish OTL people as witnesses to give credentials to Berning. We all know Doctor Gizmo and all know hi...

I don't know why the Berning topic gets everyone so worked up. No need for another ZOTL screaming contest. Is this not a hobby where we explore many solutions? It is a difficult subject technically. I for sure can not speak about th...

Merlin,
as the person who read my site you might know that one of the few dominating idea of my site and my personal audio interest is the recognition of the following rule as an absolutely desirable aim:

No, I wouldn't dream of driving my SL600s with the Berning. My understanding is that with their low sensitivity and lowish impedance, the SL600s need current. The Rotel is capable of delivering 150A into 0.1R (for short 10 microsec bursts), and seems...

Hi,I have just received a Yamamoto A-02 amplifier from Shigeki. It is a 2A3 / 45 switchable amp, not available in the EU. It is supposed to be Yammies top amplifier. I bought it in JP and sent it to Shigeki for new 230V transformer...

Thanks, Merlin. Do you know what switching frequency Berning use for his pulse converter?...
