Sony CDP-5000
Sony CDA-5000
Sony CDP-5000S
(1982 - 1984)

While several other brands had players like the CDP-5000 at the time, taking on the "console" look of the pro LP or RtR machines of the 70s, the Sony was the very first CD player available to the (rich) public, in its CDP-5000 + CDA-5000 guise. Denon and JVC/Victor quickly followed.
Sony then officially launched the famed CDP-101 and CDP-701ES.

Available at first (but shortly) with the CDA-5000 unit, a 1 meter-tall computer with a monochrome display, meant to access servicing data, key-chaining units and look damn' futuristic :-)

The CDP-5000S (shown here to the left, still tagged "CDP-5000"...) had 16Bit Dual-DACs, 13,3ms locking/programming accuracy and 52kg on the balance. Yes : fifty-two.

It may seem like an old thingy, sure. But it ain't: the 5000 and 5000S used Sony's first Fixed Pickup Mechanism !
A system reintroduced in 1994 with much marketing efforts (and raving reviews).
What do you do when you've made a full circle? Start all over again, at step 1982 :-)

The 5000S was fairly quickly replaced by the (much smaller) CDP-3000 and CDS-3000 professional combo, at the time when Philips introduced the tentative LHH 0502 and, rapidly, the monster LHH-2000.
