Up to 1,2kW output at 1 Ohm, yes : your windows will rattle. And in Class A mind you !
That feat is possible by way of the Hyperbolic Conversion Class A circuit which you can read all about just by clicking the USER button below.
Also part of this extremely rare monster are 100µ thick copper film / glass epoxy boards, hi fT (power buffer amplifiers), six pairs of Sanken's 2SA1216 / 2SC2922), four pairs of Toshiba 2SJ123 / 2SK442 MOSFET's, four ELNA Great Supply caps, strictly non-magnetic metals for the enclosure, chassis and 2,5cm extruded aluminium front, walnut sideburns, carefully designed heatsinks for optimal cooling and absence of resonance, gold-plated brass terminals, oxygen-free copper bus bars and large logarithmic compression peak level meters.
And even a photocoupler remote terminal so the MX-10000 can be powered on by the CX-10000.
And specs to die for.
And pity only around 250 MX-10000 were made.
This 2009 post was culled from several sources : the german edition of the dedicated 10000 catalog, various japanese publications (Stereo Sound, Audio Accessory etc) and the english edition of the dedicated 10000 catalog.
The latter was sent by Richard Burn, without whom putting all of these partial sources together wouldn't have been possible.
2011 : I have finally found the original japanese catalog but it hasn't arrived in Paris yet.
