The Fidelix Staccato

There seems to be a Japanese maker of high-end audio equipment that makes his own Stax driver. Looks very cleanly-made, but I don't know how much of this is a unique build versus knowledge already known in the Western Stax community. I'm particularly interested in hearing the DIY group's thoughts on the simplified schematic he's posted. Is this anything unique/interesting? Or just a rehash of existing designs?

It is very much a rehash of older designs and nothing unique there.  The "special bias supply" also doesn't hold a lot of water but good for them to get somebody to give them a patent on something nobody cares about. 

In terms of performance this is worse than the new SRM-400S for a lot more...and the 400S is a pretty crummy amplifier.  A huge step back for Stax in performance. 

Thanks for confirming, spritzer. I had a feeling, the description was focused on a lot of fairly flowery technical language— the only part that sounded potentially interesting was the "special bias supply". 

It is also fairly low powered too, those transformers are just two 12VA units and with a resistor current source for the output... not a whole lot of potential.
