Back in 1996 Be Yamamura and Robert Churchill introduced to the UK, a range of full range bicone speakers driven by current source amplifiers. Very stylish products, even their retail studio was located in a wing of a castle!
Their Dionisio 27 was listed for 25000 UK pounds ex VAT back then! Gallery stuff.
Mr Pass did you ever have a chance to listen to those products?
Having read an interview by Be Yamamura at the time your new stuff and findings brought a Deja Vu feeling.

No, they forgot to send me a pair.

I was under the impression that the amps were tubes, but
haven't gathered any more info that except the photos. When
it came time to revamp the Claw, the Yamamura shape was an
inspiration. Of course I had to make it bigger, if less elegant.

:cool:

Mr Yamamura used to make excellent tube amps but in that interview he actually said that when it comes to drive a single loudspeaker unit at a certain impedance the 'trans-impedance' amplifier is a world apart. He also maintained the importance of excellent resistor component quality for such amps. He certainly converted to current source amps since those findings. His amp products could burst into flames if illtreated though due to lack of protection circuits!
