Post Subject: Observation from 2006: Zarathustra IIPosted by Romy the Cat on: 1/1/2007
Over the course of the enter 2006 Dima and I were involved into the Zarathustra II saga. It took countless phone calls, countless emails, a lot of thinking, numbers of shipments and many hours for Dima and me to propagate the project to it semi-completion. Actually, Zarathustra II if pulley Dima’s project and he builds the amp I juts provide some administrative help. It was a big surprise to me that to PROPERLY make a hybrid amplifier is way more expensive and complex then to make SET. Sure, we went in Zarathustra II for some very obnoxious demands. The amp is slightly more then 150W in pure class A, without switching into class B… and semi-regardless of the load… (!!!) It has quite a few very interesting features that I never seen anywhere. Also, I think it is the smallest class “A” 150Watter then I ever seen. On the negative side – it is expensive (It would be around $7K of self-cost) and takes a LOT of blood to make it. Still, the 6E5P in SRPP wth Melquiades' bias driving the in-choke-regulated 5A output stage with Dima's own “Newton-bias” and sitting deep into the mode of “ static current and voltage sufficiency” (regardless of load!!!) should be VERY-VERY interesting. Will the Zarathustra II a conceptually “perfect” powerful amplifier? Well, we throwing effort and money to the problems and try to see what will happen. Anyhow, it will be coming through soon and if some of you have a serious installation around sub-95 sensitive speakers within Boston-Philadelphia corridor and if you would like to experience “what else is possible” in powerful amplification then let me know and I might swing by. I will not be able to use the Zarathustra II in my own installation full-range and I would like to give to the Zarathustra II a run on somebody else’s big, full-range speakers.
