On the evening of August 31th 1982, SONY, CBS/SONY, Philips Netherlands and POLYGRAM jointly held a press conference on the digital recording format CD, and decided to start selling it in Japan from the autumn onwards. The diameter is only 12cm, recording lossless digital signals, non-linear playback, which means free and fast music selection. Being able to be used semi permanently, CDs have achieved the dreams of many music fans. And Sony launched its first CD player, the CDP-101, on October 1, 1982, with a price of nearly 170000 yen, which is difficult for ordinary consumers to accept. After entering 1983, other companies' CD players also went public one after another, and the sales situation was very good. However, the following short period of sales stagnated. It turned out that the people who purchased CD systems at that time were mainly Hi Fi enthusiasts, and most people still preferred LP that had already integrated into their daily lives. In the United States, VHS video tapes also stand out, and people cannot find a reason to replace them. In order to save this decline, Sony's audio business unit led by Takashi Daizeng developed a product D-50 with a thickness of about 4 CD boxes, which is the ancestor of modern portable CD players.
In the 1980s, DISCMANs generally had the same sound quality and powerful headphone output power as low-end CD desktops, but their shortcomings in portability and power saving performance were fatal. At present, there are still quite a few of these super antiques for sale in second-hand markets around the world, and they have become the target of collectors and the favorite of the student group among HIFI earphone players.
The D-50 was launched on November 1st, 1984. The selling price is 49800 yen. 127×36.9×132.5mm. There are two colors: red and black. Powered by a massive battery pack, it has all the functions of the CDP-101 except for remote control and repeat playback. The early DISCMAN, due to its large size, was equipped with a dedicated strap for carrying when going out. It has been in use for 5-6 years since the D-50. The combination of D-50 and SONY active speakers unexpectedly became a popular small CD player combination at that time. Since its initial launch, its sales in the depressed CD player market have been better than expected. The small CD player after D-50 was named Discman by Sony and is now called CD Walkman.
On October 21, 1985, D-50MK2 was launched. The selling price is 49800 yen. Using a 16 bit single crystal D/A converter, the battery box is separated to form a base, and the body is made thinner, which makes it much lighter and greatly improves portability. Has extremely calm timbre, extremely wide sound field, and excellent transparency/sound density/image density/spatial performance. It is SONY's second CD Personal stereo and the world's first CD Personal stereo called Discman. This model of DISCMAN has become the prototype of most DISCMANs in the next four years. The design of the modern CD Personal stereo is not divorced from this design. The materials used for this model are not comparable to ordinary low-end CD players.
The D-700 was launched on October 21, 1985. The selling price is 49800 yen. 130×48.7×193mm. This is a fully functional DISCMAN, which not only has most of the functions of a desktop CD player such as a maximum of 16 songs RMS, one track replay, interval replay, random playback, and AMS for track search, but also has an FM radio head built-in. It is a model with built-in AC power supply, strictly speaking, it cannot be called a DISCMAN but a desktop computer. It was the first car mounted model and one of the ancestors of car mounted CD playback systems.
The D-55T was launched on April 1st, 1986. The selling price is 57800 yen. 125.9×31.1×131.8mm. Equipped with powerful radio functions, including 4 to 12 channels of TV audio, FM 76-108 MHz (TV1-3 channels), and medium wave 525-1605kHz AM radio. The playback function is the same as the D-700, and the D-50 adds functions to reduce power consumption to 2.6w. There is a battery case base that can use 8 No. 5 batteries. When using this battery case, the CD usage time is about 3 hours, and the radio reception time is about 25 hours, In the CD Personal stereo market at that time, it was definitely a long time to play. Although the D-55T was very power consuming by current standards, it was regarded as a leap in technology at that time. The sound was thick and thick, and the radio effect was excellent, almost comparable to the low-end radio head.
The D-100 was launched on November 1st, 1986. The selling price is 49800 yen. 125.18×19.8×132.8mm. The playback function is very complete, with 1 track/full track/interval replay, 21 tracks RMS, and for the first time paired with a remote control. The attached dedicated charging battery base is very thinly buckled at the bottom, and the included charging pool can last for 4 hours. Compared with most of the later DISCMANs, the sound of the D-100 is extremely neutral and less stained. As a DISCMAN, it is impeccable. As always, the thrust is huge, and it is no inferior to many Headphone amplifier.
D-30 was launched on February 21, 1987. The selling price is 39800 yen. The same size as the D-50, the continuous playback time has been increased to 5 hours. This model of DISCMAN is said to be one of the most powerful DISCMANs, with high impedance headphones that barely break the sound.
March 1987/D-2001 introduced. The selling price is 79800 yen. This is an alternative DISCMAN, strictly speaking, it cannot be considered a DISCMAN. This magazine sized DISCMAN has a built-in 50W amplifier, which allows for direct promotion of speakers, but the market is not buying it and sales are not high.
D-600 was launched on June 21, 1987. The selling price is 32800 yen. The appearance of a round head and a round brain, with its massive volume and astonishing output power, is unfortunately a bit rough.

November 1987/D-T100 launched. The selling price is 59800 yen. It is an improved version of the D-55T, which is smaller and thinner, and has longer playback time. It is the radio model of the D-100.

Having a calm tone and excellent air sense, similar to the taste of early landlines, the sound field/transparency/sound density/image resolution/spatial sense/dynamic performance is top-notch. The first time the battery compartment was integrated into the DISCMAN interior was the Ultrathin D-100 Evolution Edition. But compared to previous products, the sound quality of the D-150 has shown a downward trend, but it is still a beautiful DISCMAN, and the thrust is still as high as ever.
The D-40 was launched on March 1st, 1988. The selling price is 39800 yen. 9v. Available in white and black, it is a successor model to the D-30.

The D-20 was launched on September 21, 1988. The selling price is 27800 yen. 9v. It is SONY's first DISCMAN that takes the civilian route. To be honest, the sound is not very good, and the selling point is probably 6 hours of playback time.
D-82 was launched on October 21, 1988. The selling price is 22800 yen. 9v. It is a popular model. It is still a rare DISCMAN that can play 8cm CDs, with low sales.

On January 21, 1989, the D-250 was launched. The selling price is 42800 yen. 20.8mm. Using the same D-Z555/150 series bearing plate general type, made by German Burr Brown, PCM66P D/Ax1. The timbre is bright and warm, with excellent performance in sound density, layering, positioning, and imaging. The sound is very sweet with a good musical atmosphere, especially the magnetic nature of the human voice and the wiping box sound of the cello. It is most suitable for listening to human voice and string music, which is difficult for most landlines to achieve. Born out of the D-150, the sound of the D-250 has regressed compared to the D-150, with a much thinner sound base and a pseudo hard embellishment in the mid range. It can be said that the sound of the D-250 is a typical cold and hard Japanese sound. Of course, if compared to the current trendy CD WALKMAN, the D-250 still has high-quality sound quality. It is the last DISCMAN designed based on the D-50 and is a mature model mass-produced by SONY.
D-90 was launched on February 21, 1989. The selling price is 37800 yen. 8MW. 9v. For the first time, using D.B.B (DIGITAL BASS BOOST) sound technology and achieving universal use of DISCMAN dedicated batteries and No. 5 batteries, it is also SONY's first model to reduce the output power of headphones to around 8MW.

The voice is extremely soft and beautiful, clear and gorgeous, with high resolution, transparent sound quality, clear hierarchy, and very appropriate audio-visual ratio. The timbre of each frequency band can be handled very roundly and delicately. Listening to string music and small weave chamber music is the best of Personal stereo, but it is weak at low frequencies. The D-Z555 has little natural power, and has no connection with the big earphone with fever. It was Sony's top tier model back then, the Sony Discman 5th anniversary model, and also the king of Sony Discman. It is a very awesome DISCMAN. Its appearance has become a model for CD Personal stereo to overwhelm low-end desktop computers.

In a 1-bit DISCMAN, the sound quality of the D-303 is outstanding, with a very transparent and gorgeous sound quality, a wide and natural sound field, and strong resolution. However, compared to earlier multi bit machines, the D-303 is clearly not an opponent in terms of sound quality. There are too many sound dyes, and the output power of only 5 milliwatts has been reduced to the point where it affects the performance level of headphones. The workmanship of its circuit output end also shows obvious signs of laziness. It is a DISCMAN praised by domestic Personal stereo players. It is a high-end machine, famous for a time.

It is a very convenient design. The sound is very neutral and balanced, with no unnecessary rendering. The transparency is excellent, and the mid frequency performance is commendable. The sound quality is round and delicate, with clear layers, and the sound field is wide. The sound density, speed, and proportion are all excellent.

In terms of wire control, the orange red backlight wire controller RM-CD01ELT, which is still dedicated to E01, is used. The clamp can rotate 360 degrees, which is very eye-catching. The 1400mAh strip battery has a playback time of up to 62 hours. Made in Japan. The performance of transparency, sense of hierarchy, degree of image and analytical power is quite good. The sound quality is clean, clean, elegant and transparent. It is suitable for Light music, pop music, and classical music. From the rigorous and less stained sound, we can vaguely distinguish the shadow of early DISCMAN. Unfortunately, the taste is just a taste. Strictly speaking, its beautiful voice is not at the same level as the classic. It is the 20th anniversary model of the Personal stereo, the 15th anniversary model of Sony Discman, and the crystallization of Personal stereo technology. It is the most modern and futuristic model with great collection value. It was the final swan song of SONY DISCMAN, even though it was no longer called DISCMAN at this time. After that, Sony continuously fought for the world record of thinness, and the sound broke the record again and again, with output power decreasing again and again. By March 1999, CD Walkman had sold a total of 46 million units.
D-E815 was launched on October 1st, 1999.
D-Ej915 was launched on October 1st, 1999. The sound is soft and elastic, with good performance in high-frequency, low-frequency, and layering, making it a good machine to listen to. It can be said that this is truly the sound quality of a CD, which is of course compared to other models he has launched before and after.
From the perspective of sound, appearance, and market reaction, the SL-CT570 should be Panasonic's iconic product in the mainland market. Therefore, let's briefly introduce the early products before the 570. (Technics information is difficult to find and is not easily accessible to ordinary people, so no such information was collected)

Since Panasonic is mentioned, how about not mentioning Technics. All three masters are classics. Especially unique is the XP7, which is used to connect with Lehmann or SOLO, and there are also people pushing HD600 and K701. The sound is astonishing.
Perhaps too much energy has been put into the research and development of tape Personal stereo. In the field of CD Personal stereo, AIWA is completely inferior to SONY in terms of quantity and quality. However, it would be biased to say that AIWA's CD Personal stereo does not have a desktop model. Among AIWA's high-quality CD Personal stereo, XP-7 is undoubtedly the most outstanding representative.
XP-7 was launched in 1992. Using 1 BIT dual DAC, 8x ultra sampling digital filter, 2-segment DSL dynamic ultra linear bass system, plastic material body, heat resistant design of the host, 30 minute fast charging, 24 music programming playback, 1/all/A-B interval repeat playback, random playback, battery level check display (LCD), already equipped with square port fiber output at that time. Accessories: Card type remote control, capable of playing directly with 10 buttons; The earplugs of the wiring controller are gold bar V14; PB-50 lead-acid rechargeable battery; Use two No. 5 battery racks; 9V power supply with model AC-A98. The upper cover design of the host is very unique, with a transparent edge design, which allows for a clear view of the disc's rotation during playback. The most unique feature is that when using the power supply, the edge of the transparent upper cover has a circle of red backlight, which is very beautiful. At the same time, the LCD screen also has an orange backlight. It is the leading model of AIWA CD Personal stereo. The sound quality is very warm, and the DSL bass gives a very shocking feeling. The low-frequency feel is full and extremely strong, making it perfect for listening to pop and rock music. Although an 8-fold oversampling digital filter is applied, compared to the SONY D-Z555, which also uses this technology, the sound of the XP-7 is clearly not delicate enough, and the lines appear relatively rough. Compared to SONY's contemporary high-end models, the XP-7 also has obvious disadvantages. Firstly, there is no metal body used, and the entire machine is made of plastic material, which is much lower in grade; Secondly, when using the power supply, the heat generated is too high, and the buckle of the car tray bracket at the bottom of the body is too hot to touch with your hands.
XP-6 was launched in 1992. It is a sub product of XP-7. Except for the absence of a remote control, other features such as appearance, functionality, and accessories are identical to the XP-7.
XP-77 was launched in 1993. 1 BIT dual DAC, 8x ultra sampling digital filter, heat-resistant design, 2-segment DSL dynamic ultra linear bass system, 24 music programming playback, 1/all/A-B interval repeat playback, random playback, battery level check display system replaced with a 3-point LED indicator. Added oil pressure (liquid) shockproof device without fiber optic output. From the perspective of appearance, the XP-77 is basically not different from the XP-7, but the workmanship appears not to be so delicate. Functionally, it is almost the same as XP-7. When using the power supply, the LCD screen also has an orange backlight. In terms of accessories, there is also a card type remote control that can play directly with 10 keys. The earplugs of the connected controller have been replaced with V16, and the PB-50 lead-acid rechargeable battery, which can cause significant environmental pollution, has been improved to a nickel hydrogen MHB-120. The power voltage has also been reduced to 4.5V. The effect of XP-77 is much inferior to that of XP-7, with stronger bass that only adds volume and sounds very enjoyable. This may be the most powerful bass for listening to sound, but the sound permeability is not as good as XP-7, and the sound field is not as good as XP-7.
Introducing XP-66. It is almost identical to the XP-77 in all aspects, except that there is no remote control, and the MHB-120 rechargeable battery has also become an option.
Launch XP-33. Continuing to streamline on the basis of XP-66, it also eliminates the backlight function of card remote control, rechargeable battery, and LCD display screen, especially the AIWA logo is not metal, but directly printed on it.
Launch XP-R90. It is a model equipped with an FM/AM synthetic tuner. Other aspects are basically the same as the XP-77, except that the XP-R90 does not have a card type remote control. However, the bass of the R90 is very good.
Launch R970. It is another CD with a radio receiver, not very good in appearance, but the sound quality is very good. The high and low frequencies are very harmonious, and when paired with the original 141, it can achieve the best sound. However, using the 553543 loses the original sound of the device.
The XP-80G was launched in 1994. The output power is 14MW. Using 1 BIT dual DAC, 8x ultra sampling digital filter, heat-resistant design, 2-segment DSL dynamic ultra linear bass system, 24 music programming playback, 1/all/A-B interval repeat playback, random playback, 3-point LED battery level indicator, oil pressure (liquid) shockproof device, 3.5mm video recorder output terminal. Equipped with complete KARAOK functions: a 3.5mm microphone socket with volume adjustment, a digital echo sounder with volume adjustment, and singing sound attenuation/attenuation function. It is a very special model. The suffix G of the model represents the ability to play CD G, including various formats such as China, Europe, the United States, Taiwan, and Japan. Accessories include V16 earplugs, audio/video cable, and power supply. This machine is not much inferior to the XP77/R90 in terms of sound quality, and its main selling point is its support for CD-G. Unfortunately, this unpopular CD can hardly be found in the world, so it has little practical significance.
Launch XP-S35. In fact, it is a combination of XP-33 and dynamic speaker SC-A25.
Launch XP-55. It is the first model equipped with an EASS electronic shockproof system. Interestingly, the XP-55 not only has EASS electronic shock absorbers, but also is equipped with old-fashioned hydraulic shock absorbers, which can be considered a dual safety device.
In 1995, the XP-700 was launched. It is the first model to extend the old EASS electronic shock mount from 3 seconds to 10 seconds. Equipped with a 1 BIT dual digital analog converter, heat-resistant design, 2-segment DSL dynamic ultra linear bass system, 24 music programming playback, 1/all repetitions, random playback, 3-point LED battery level indicator, and a 600MAH NB-3A rechargeable battery, the capacity is half that of its predecessors.
The XP-300 was launched in 1995. It is the first model equipped with a DSP sound system. Equipped with 1 BIT dual digital analog converter, heat resistant design, 24 music programming playback, 1 song/all repeated playback, random playback, three-point LED battery power indicator, DSP digital echo effect processor has five modes of pop/rock/jazz/live and digital bass, similar to the M.S.P sound effect system used on tape Personal stereo. However, in order to achieve balance and save costs, the XP-300 is not equipped with the EASS electronic shock absorber that has already been standard equipment. After 1995, AIWA CD Personal stereo basically has no models worth collecting.
Philips is the number one electronic brand in Europe, with stable and reliable product quality.
D1, the use of Philips' discontinued rocker arm smooth head CDM2 makes data as accurate as possible and has a longer lifespan. The simplest operation method is to have only three controllable buttons and one switch on the entire machine. Turn on the switch and the machine will automatically play without stopping, without any programs playing, or any programs unrelated to playing CDs. Proud of the super shock resistance of current models in the same class. It is powered by 8 AA battery inside, and can also be driven by an external 9V power supply. There is also a hanging hole on the side that wears shoulder straps. This is a super portable CD monster. Exquisite craftsmanship and advanced materials ensure that all movements and functions are still perfect 16 years later. Exciting HIFI sound quality drives high impedance headphones with strong power.
CD10, wiredrawing panel and slide bar Potentiometer have not made any sound after so many years. It is the only PHILIPS exclusive secret door CDM4 PRO skinhead in CD Personal stereo with super signal picking ability. It can read the disc very quickly, about 1s or even shorter. The music of music selection also sounds when you just leave the button. Even 18 years later, it is still so fast and there is no slight. I have to admire the genuine materials of European manufacturers for this. This makes CD10 an absolute masterpiece of the last century. The function is very simple, just two playback modes and two time displays, even quick search and song selection require buttons to switch. There is an integral socket at the rear of the machine, which can be inserted into PHILIPS's own AC/DC module. From the perspective of having a DC module, it belongs to the category of Personal stereo CD, not a small console. Balanced timbre, without any harsh mid to high frequencies, low frequencies are neither fat nor thin, and the dynamics are also quite large. The output of headphones is not small, usually between 2-3, which can drive earplugs and low impedance headphones.
Attached is a brief description of the CDM4 PRO: This optical head component is expensive, and generally only mid to high-end CD players are equipped with this system. The Pro version of CDM4 is professional and made of cast aluminum. The large glass lens is a special product from a German high-end lens manufacturer, and the motor is also a high-precision product. The use of CDM4 Pro on Philips' previous advanced products, LHH 500R to LHH900R (including Maranz's advanced products), demonstrates Philips' importance and confidence in CDM4 Pro. In fact, CDM4 Pro is not only very sturdy and durable, but also has a much lower error rate when reading CD information than traditional turntables. Its sound performance is also quite accurate and vivid. Except for Philips and Maranz's own use, other products can only be found on top products such as Mark Levison No.31, Jadis, and Primale. For example, MARANTZ CD16/MERIDIAN CD506/Primale 204, etc. The most amazing thing about CD10 is that it has no ear distinguishable defects in the full frequency range, and its analytical power is amazing, with a quite German equipment style.
AZ6819/6829, using PHILIPS unique 1Bit Bitstream Conversion bitstream, Master Clock dual D/A convergence technology, and European DSP system. The difference between the two is that the 6829 does not have wireless headphones. The sound quality is very balanced and natural, with warm, full, and delicate tones. At the same time, it combines 16bit resolution and 1bit softness. The sound quality is not comparable to ordinary Japanese models and machines. Made in Austria. It is the highest model of PHILIPS Discman. The Japanese Discman ranks first, known as the Mini LHH, and is the closest to the Hi End level Discman. The difficulty of collecting and the high cost of collecting have gradually made 6819/6829 a myth.
