PHILIPS CD-850 (1991) | Bitstream Conversion

 

For those who want to enjoy the purest, undistorted digital sound. For those who desire even more accurate reproduction of the weaker passages, and for those who opt for the most advanced user-friendly features. After one of the most renowned Japanese Hi-Fi magazines has named this innovation (PHILIPS ONE-BITSTREAM) the greatest sound innovation since the invention of the Compact Disc, Stereo Sound magazine named Philips' new CD player with this technology "Component of the Year." Radio Technology magazine of Japan gave it the title of "Component Grand Prix" - and Stereo magazine promptly named it "Best Buy." It's all about the small but crucial part of the CD player: the D/A converter. Its job is to convert the CD's 16-bit digital signals into analog. BIT-STREAM CONVERSION. If the signals are not converted accurately by the standard 16-bit D/A converter, there are 65,536 possibilities for distortion to occur. In an attempt to develop the technique, some have gone from 16-bit to 18-bit and so on. The ability to control the sound curve increases, but unfortunately so does the risk of error. This is where Philips found the philosopher's stone. By converting the 16-bit signals to a 1-bit data stream with 256 times oversampling, the risk of both nonlinearity and distortion is eliminated. This unique Philips technology One-Bitstream is the only system on the market that works with true 1 bit resolution. You will hear the difference immediately; smoother midrange, a better defined sound image and a firmer bass reproduction. For the top model, the CD 850, Philips have developed a sophisticated high-end solution. Equipped with two One-Bitstream D/A converters that work differentially, the signal-to-noise ratio is increased by a further 4 dB. With this remote controlled CD player you can play your favorite songs or passages from your entire collection. Store CDs in two separate FTS memories. For example, split them into classical or pop, his music or her music. You can also program the tracks. This is very convenient, because as soon as you play a CD, the name of the track, composer, soloist, or singer automatically appears on a display. This extensive display also provides information about the extensive operating options. Besides FTS, you can also play directly or pre-program a specific playing sequence using 10 numeric keys. Music Scan gives you a quick overview of a CD's contents by playing the first 10 or 20 seconds of each track. Another new feature is the ability to customize playback mode and display brightness. This CD player also features all of this, including a headphone jack with volume control and all the classy features of every Philips CD player.

Aurex Micro 15 (1978)

 

The micro 15 components from Aurex(Toshiba) from 1978 feature a digital quartz synthesizer tuner, double-sided circuit boards, a novel through-hole soldering process, improved copper plating, and a novel capacitor winding. But the most revolutionary aspect is the super-chip technology. This simply means that all the electronic circuits necessary for a high-quality hi-fi system are packed onto the smallest possible circuit boards. This allows the individual components to be built so compactly that they can be installed anywhere. And so powerfully that they deliver their full potential in any location. After all, 100 watts is something that even untrained ears can quickly grasp. Power Amplifier SC-M 15: 2 x 50 W @ 4 Ohm, Distortion: 0,02%, Dimensions 257 x 106 x 211 mm.
