By looking at it this looks like a magnetostatic (isodynamic?) design rather than a ribbon. There's a Danish guy who has done good research on the subject: http://www.soundimage.dk/Different-col/Magneto.htm (you can click on "ribbon" for more info). It might be useful
He himself uses a Dynasonic @ ~97dB -- which means you'll need to double up the power for the target ~103... Haven't heard it.
I have heard the expensive Raven which is over 103dB over 7 kHz or so. The smaller and cheaper Raven-2 was a bit over 100 over 10-11kHz. Also the equally French produced "Audio Valve 3"(i think it was 3--a cylinder) is very similar if not identical electrically to the Raven 3. There, too, you get ~103 at 10kHz or so. Finally, the same guy that designs the Ravens has his own line called "Alian" -- but again, rated sensitivity is ~98dB.
Last, there are the chinese products -- under a number of names. I assume some of the above are also sourced in China, but am not sure.
