The future of audio as seen by Technics in 1988 was an advanced Hi-Fi system equipped with a digital amplifier, Satellite broadcasting, DAT, and CDV. High-quality digital sources were appearing one after another. It was against this backdrop that the D5000 Digital Component System was born. Its cutting-edge capabilities go beyond simply being equipped with a digital amplifier. Its digital optical link transmits CD digital signals purely via optical fiber, and it supports three digital formats, allowing digital connections for CD, BS tuners, and DAT. It also features video input/output terminals that are compatible with the latest AV trends, and a new edit guide. Digital optical links transmit digital signals using light, in order to deliver sound to the listener's ears as faithfully as possible, the D5000 sound. This system uses a digital optical link. The CD's digital signal is transmitted directly to the amplifier via optical fiber. The amplifier's D/A converter converts it into a music signal. This eliminates the influence of noise during transmission and it can be expanded to satellite broadcasting and DAT. This "digital amplifier" was the first mini component system to support three digital sources, allowing you to input digital signals from not only CDs but also BS tuners and DATs as they are. Since the number of analog signal transmission paths is reduced, the high fidelity sound of new digital sources can be fully enjoyed. The D5000 is equipped with three video input terminals that can accommodate such cutting-edge AV equipment. With the D5000 as your key station, a new AV world will open up. Ease of use has been further improved with the new edit guide. Simply press a button to automatically edit tracks from a CD onto a tape without any cutoffs.

PIONEER CT-F1000 (1977) | UNI X'TAL Ferrrite

 

When Pioneer introduced the CT-F1000 (CT-F1000 worldwide) in 1977, it did so with one of the boldest advertising campaigns of the decade — something that would likely be impossible today. The campaign opened with this striking message: “For years, Nakamichi has enjoyed a reputation for building the world's finest cassette deck. Now Pioneer is introducing something Nakamichi won't enjoy at all: the Pioneer CT-F1000 — a cassette deck that offers all the features and performance of Nakamichi's best deck, at less than half the price.” At the time, the Nakamichi 1000II sold for around $1,650, while the Pioneer CT-F1000 retailed for roughly $600 USD (1978). This bold positioning made the CT-F1000 a serious contender in the world of high-end hi-fi cassette decks.

The CT-F1000 was a three-head cassette deck featuring Uni-Crystal record and playback heads, engineered for maximum durability and sound precision. Unlike most decks of its time, it included two separate Dolby noise reduction circuits — one for recording and one for playback. This innovative setup made it possible to monitor Dolby-decoded recordings in real time, a capability not available on decks with only one Dolby circuit. Pioneer equipped the CT-F1000 with a dual-capstan, two-motor transport system — one motor dedicated to fast-forward/rewind and another for capstan drive — ensuring smooth tape handling and excellent speed stability. The playback-only pitch control allowed users to fine-tune playback speed, correcting tapes recorded on machines with inaccurate speed calibration. It also supported Normal, Chrome, and Ferrochrome tape types, providing maximum flexibility for different recording needs. The CT-F1000 was packed with professional-level features that made it a favorite among audiophiles and studio users alike:

Dolby noise reduction calibration with front-panel test tone

Memory Stop / Memory Play functions

Large logarithmic VU meters for accurate level monitoring

Direct logical controls for responsive tape operation

MPX filter for clean FM radio recordings

Mic/Line mixing and timer recording capabilities

Tape-end warning and full auto-stop

The front panel was machined to EIA (Electronic Industries Association) rack-mount standards, making it suitable for professional installations. Optional Pioneer JA-R102 handle adaptors were also available, along with an optional wooden case for a more luxurious finish.

Specifications:

Wow & Flutter: 0.05% (WRMS)

Frequency Response:

Normal: 20 – 17,000 Hz

Chrome: 20 – 19,000 Hz

Ferrichrome: 20 – 19,000 Hz

PIONEER HPM-100 (1977) | The Legendary 4-Way Speaker

 

When Pioneer designed the HPM-100, every component served one purpose: to deliver pure, distortion-free sound. At nearly 60 pounds per speaker, the HPM-100 is no lightweight by accident. Its cast aluminum driver frames replace the usual stamped steel, eliminating unwanted resonance and ensuring that only the cones vibrate — not the enclosure. The oversized magnetic structures provide tight control and low distortion, while the dense compressed-wood cabinet projects the full musical spectrum outward, instead of absorbing energy as ordinary particleboard might. Engineered by Bart Locanthi — A Legacy of Innovation. The HPM-100 was designed under the guidance of Bart Locanthi, a legendary engineer who previously shaped the sound of classic JBL studio monitors. At Pioneer, Locanthi brought the same rigorous acoustic philosophy to a new generation of loudspeakers, blending American studio power with Japanese precision engineering. The result was one of the most balanced and dynamic loudspeakers ever made for home use — the High Polymer Molecular (HPM) series. 

Advanced Acoustic Design. Inside each Pioneer HPM-100 lies a wealth of thoughtful engineering:

12-inch Carbon Fiber Blended Woofer — deep, realistic bass with speed and control.

High Polymer Molecular Supertweeter — extended high-frequency response and transparency.

Midrange and Tweeter Drivers — light yet rigid cones for accurate, low-distortion reproduction.

12.5 feet of internal damping material — minimizes resonance and maintains tonal balance.

Aluminum fasteners — aircraft-grade hardware ensuring structural stability over decades.

Together, these features form a 4-way, 4-driver, bass-reflex system capable of handling up to 100 watts RMS with clarity and effortless dynamics. Designed for Real Music Lovers, as Pioneer’s original brochure stated: “You’re going to pick the speaker that sounds best on the music you play the most — and anybody who chooses otherwise is kidding himself.” Whether your passion is jazz, classic rock, or symphonic recordings, the HPM-100 delivers a strikingly natural tonal balance. Its wide frequency range, dynamic capability, and physical presence made it a favorite among both studio professionals and serious home listeners. The HPM-100 remains one of the most collectible and respected loudspeakers of the 1970s hi-fi era. Combining robust construction with forward-thinking design, it continues to impress audiophiles who seek the realism and power of true high-fidelity sound.

Onkyo D-5 (1981) | Pure, Natural, and Expressive Sound

 

Just as musical styles evolve, so do the trends in sound reproduction. Onkyo’s approach to speaker design has always focused on natural expressiveness—creating sound that stays true to the original recording without coloration or distortion. A speaker’s true character depends on the quality of its diaphragm, and Onkyo has achieved remarkable purity with its innovative Delta Olefin diaphragm. Unlike conventional materials, Delta Olefin offers minimal resonance and fast decay characteristics, delivering smooth, accurate sound reproduction across all frequencies. In technical terms, it provides a low Q factor and quick transient response—but from a musical perspective, it means the speaker “breathes” naturally, resonating only with the music itself. The result is a clear, detailed, and emotionally engaging sound that faithfully reflects every nuance of the performance. This advanced three-way speaker system showcases Onkyo’s commitment to high-fidelity engineering:

Low frequencies: 28 cm cone-type woofer with a Delta Olefin diaphragm and dust cap. Equipped with a four-layer voice coil and Capton bobbin for improved power handling and precise bass control.

Midrange: 10 cm cone driver, also crafted from Delta Olefin, housed in a dedicated 1-liter sealed enclosure to eliminate interference and ensure pure midrange reproduction.

High frequencies: 2.5 cm soft-dome tweeter made from specially developed chemical fibers with uniform thickness, achieving up to 2–3 dB higher efficiency than conventional designs.

Fine-tuning: Independent level controls for both midrange and high frequencies allow personalized sound adjustment.

The result is the distinctive “Delta Olefin Sound”—a long-awaited breakthrough that meets the demands of  discerning music enthusiasts. With exceptional clarity, natural tonality, and sensitivity to every genre, this Onkyo loudspeaker stands at the forefront of modern high-fidelity audio. Maximum power: 120W | Frequency range: 33-30.000Hz | Impedance 6ohm | Size: 350x630x325mm (W/H/D) | Weight: 16,5kg

WEGA frogpit study 1978 | A Vision Ahead of Its Time

 

This rare music center prototype designed by Hartmut Esslinger of frog design offers a fascinating glimpse into the evolution of modern hi-fi systems. Keen observers will immediately notice its resemblance to the later Wega Concept 51K from 1979 (see here). The system was envisioned as a set of modular components, each with its own dedicated controls and display. These modules included a three-head cassette deck, a digital radio-timer unit, an amplifier and equalizer module, and even a Laser Pick-Up — essentially a CD player concept long before the real thing existed. Now you may ask, how could a CD player be part of a music center in 1978, when the Compact Disc wasn’t introduced until 1983? The answer lies in the innovative collaboration between Hartmut Esslinger/frog design and Sony-Wega. When Sony acquired the German brand Wega, it continued to work closely with Hartmut Esslinger and his frog design studio. This partnership influenced the clean, futuristic aesthetics of many early 1980s Sony products — and also produced experimental prototypes like this one. However, the so-called “CD player” here wasn’t a Compact Disc player as we know it today. The design was actually inspired by several early DAD (Digital Audio Disc) concepts that Japanese manufacturers were testing at the time. The Laser Pick-Up shown in this prototype was part of that experimentation — a forward-looking idea that visually anticipated the CD era, even though it was never manufactured. A brilliant example of 1970s industrial design, this Wega-Sony prototype stands as proof of Esslinger’s visionary approach — merging technology and aesthetics years ahead of its time.

Onkyo Integra A-817GT Stereo Integrated Amplifier (1981)

 

The Onkyo Integra A-817GT is a high-performance stereo integrated amplifier released in 1981, continuing the legacy of Onkyo’s renowned A-817 series that began in 1980. This series of 70–80W amplifiers evolved through the decade with continuous technical and aesthetic refinements, culminating in the Integra A-817XG (1989) — the final model in this prestigious line. At the heart of the A-817GT is Onkyo’s Super Servo Integral Technology, designed to deliver pure, distortion-free sound. The W Super Servo circuit cancels distortion-causing elements, while the Super Servo Integral system suppresses intermodulation from opposing channel forces within the stereo field. The amplifier’s linear switching output stage uses a unique bias circuit that corrects nonlinearities found in traditional Class B designs, resulting in smooth, accurate sound reproduction. To achieve the highest fidelity, Onkyo implemented a Direct Tone System that uses only passive components — eliminating the need for an additional tone amplifier. This allows tone adjustments without degrading sound purity. Premium materials such as non-magnetic copper, brass, and aluminum were chosen to prevent unwanted harmonic distortion, while gold-plated phono terminals ensure the cleanest signal transfer. Even the resistors were custom-designed for optimal frequency response and minimal distortion, underscoring Onkyo’s obsession with sonic precision. The result is an amplifier that perfectly blends technical innovation and musical refinement, representing one of Onkyo’s finest efforts of the early 1980s.
