Probably the most remembered "Jubilee" or "Anniversary" series.
Yamaha spared no expense for the Centennial Series and could do so : this was before the 1987 crash and subsequent 1990s gradual retreat of all japanese brands toward the mid-end and low-end segments of the market.
The CX-10000 is a monster, a real monster with everything tripled - the chassis, the ICs, the possibilities, the VCAs and... the rarity.
The CX was highly reviewed in Japan back then, with a dedicated "Exciting Component" section in Stereo Sound. In other words : top of the pops and crème de la crème.
At least very exciting because DSP was a novelty.
Sound-processing-wise, the CX-10000 is divided in two : a digital parametric EQ plus associated side functions and a Digital Sound Field Processor ; both parts have their own D/A converters: Hi-Bit Yamaha for the DSP and Burr-Brown PCM-56P for the EQ part.
The other ICs used are exclusively Yamaha's :
3x YM3818 for DSP
3x YM3619 for 4fs digital filter (225th + 41st FIR)
1x YM3623 for digital i/o
2x YM3608 for DEQ, low/high filters & slopes
3x YM3901C for 16bit/48Khz a/d
2x YM3020 for 16bit/48Khz a/d
1x YM3615 for 18bit FS/H d/a
1x YM3023 for 18bit FS/H d/a.
The 3-band parametric EQ handles 4-step Q (0,7 / 1,4 / 3 / 6) while continuously variable low and high filters can see their slopes set at 6, 12 or 18dB/octave. All this per channel, of course !
D/A is arranged according to Yamaha's Hi-Bit fashion. Output opamps are JRC 5532D.
Two transformers for the left and right analog channels and a third one for all things digital ; the six boxes (à la Accuphase or Sony TA-ER1) hold the VCA and LPF/HPF boards while the one at the bottom of the main board shields the A/D section.
The bottom plate is made of 5mm thick steel ; gold-plated terminals (53 in toto !) are present. No S-Video plugs, though - this is 1987 !
Another touch to note is the balance ring which is exactly like that of Yamaha's 1st CD player :)
Made to feed the MX-10000 Hyperbolic Conversion Class A powerhouse.
