BeoSystem 5500. Manufactured: 1986 - 1989 Designer: Jacob Jensen Colours: Aluminium, White Beosystem 5500 - raw power, civilised manners At first sight Beosystem 5500 looked almost too refined to be a musical powerhouse.
The clean, streamlined design, devoid of buttons and dials, gave no indication of the massive potential beneath. Looks are deceptive, however. Below those polished surfaces was a technologically-advanced record player, tape recorder, radio and compact disc player, plus an amplifier that could more than hold its own among the heavyweights. Intelligent remote control Beosystem 5500 was technologically at its best - extremely powerful in design, wonderfully easy to use. Each time you gave the system an order, the light display would tell you what was going on.
Where you want - and when you like The modular design of Beosystem 5500 gave you complete flexibility in where you placed the different units.

Preliminary Pretty rare - almost Invisibilia status.
If the Dragon CT was engineered and built on Etsuro Nakamichi's specifications by Junichi Okumura at Fujiya Audio Ltd, the TX-1000's origins are... not so clear. But it isn't a wild guess to imagine Micro Seiki having a hand if not twelve fingers and just as many toes into the consulting and/or manufacturing of the TX-1000 - among others. Mr Teragaki probably had a hand in it, too. If the Dragon CT has two platters (one that is nudged, placed above one that isn't), the TX has only one platter, the rotating center of which is nudged by two motors through two plastic rotating washers.
The Quartz PLL motor itself runs in an oil bath within a "Pressure Regulation Chamber" and the shaft is finished within 1/100µ. To perfect the "multi-sourced" parts and engineering, an optional VS-100 vacuum stabilizer coud be ordered. A very interesting review (with music in mind) is available here. A real TX-1000 here. Nakamichi Dragon CT on thevintageknob.org. Preliminary Pretty rare, almost non-existent.
Given the poor sales of the TX-1000, Nakamichi needed a cheaper solution to carry its warmly received solution to the radical illness of the LP format : enter the CT. If the TX-1000 was designed by Etsuro Nakamichi (but quite probably built by Micro Seiki), the Dragon CT was "sourced" elsewhere : Nakamichi commissioned Junichi Okumura, then at Fujiya Audio Ltd, to design the CT after the basic goal outlined by Etsuro !
This explains the large differences in approach and engineering between the TX and the CT. Nakamichi DRAGON on thevintageknob.org. At least, this one is well remembered :) The usual debate surrounding the original DRAGON isn't as interesting as what this monster did represent in 1983 : it was the most one could do without actually altering the Compact Cassette format's physical structure like the ELCASET did (ie. open-reel in a cassette) or Luxman's X-3K prototype should have done by completely pulling the tape out of the cassette's shell thus removing any rotating movements from the tape.
HiFi-Do McIntosh/JBL/audio-technica/Jeff Rowland/Accuphase. HiFi-Do McIntosh/JBL/audio-technica/Jeff Rowland/Accuphase. 4430/35. The 4430 and 4435 Bi-Radial Studio Monitors were amongst the most successful professional loudspeakers ever produced by JBL.
They were in production longer than any other JBL main studio monitor, being introduced in 1981 and not discontinued until 1996 for the 4435 and 1999 for the 4430. David Smith was the engineer responsible for the system design of these monitors. The following is his account of the background and design of these systems. I came to JBL in September of 1980. It was my second job in the industry. At the time JBL had a good line of studio monitors including the 4350, the 4343 and the 4315 (a product I much admired).
Don Keele had just gotten his constant directivity horn design software going. To explain the biradial name, there were a lot of radial horns at the time. One part of the mechanical development of the 4430/35 was of the 100 by 100 horn castings. As an aside, a lot of the evolution of horns has been tied to their construction processes. Marantz Music Link Series - DutchAudioClassics.nl. The Marantz Music Link series was designed with a specific goal in mind: To provide absolutetly state-of-the-art-sonic performance in a rarely seen design package noted for both its advanced construction and its understated beauty.
Judging from highly positive reactions to the Marantz Music Link Series by audiophiles both internationally and on American shores, Marantz has achieved their goal. The Vintage Knob - Online vintage audio museum, forum and image bank. Pioneer RT-909 on thevintageknob.org. The people who designed these loved their craft and it sure still shows.
If the beautiful blue meters were already announcing what was to come all too quickly (lights, flashing leds and mute electronica), the RT-909 probably is one the very few units that properly embodies the fair balance between efficient modernism and great work. The 909 is powered by three motors within a closed-loop dual capstan path, has 4 heads (the 4th being for reverss playback) and fair but not exceptional specifications - we're not in TC-880-2, RS-1700U or even GX-255 territory. Seeing a 38cm/s or a 1/2" tape version probably would have allowed to cut some sales off the Technics RS-1500U and secured the RT-909 a place in the audio museums or more audiophile studios...
