SANSUI aelf7 (1994) | Compact Pure Compo

 

D-alpha7 - Cassette deck featuring a tray-type horizontal loading mechanism that suppresses minute vibrations of the cassette half during tape transport, improving tape transport stability and reducing modulation noise. It is equipped with an auto-bias function, which allows you to automatically set the optimal recording bias value, which differs slightly for each tape, with a single touch. It is equipped with CARS PRO (Computer Assisted Recording System PRO). With this function, the optimal recording level and recording bias value are automatically set with a single touch, and the leader tape is automatically advanced, recording is done in the original track order up to the end of side A, and the last track fades out. On side B, recording starts from the beginning of the track and fades out at the end. If the last track on the tape is less than 32 seconds, it is automatically erased. An aluminum die-cast flywheel is used to achieve high rigidity of the rotating part and tape transport stability. A center mechanism layout is adopted considering the optimal weight balance. Dolby B/C NR noise reduction system and Dolby HX-PRO to improve high-frequency recording characteristics . The display unit has a large 16-segment peak level meter. Wow and Flutter 0,06%, Frequency response 30-18.000Hz Metal.

T-alpha7 - FM/AM stereo tuner.It allows for 15 preset stations for both FM and AM. Furthermore, it features AI Area Fine Memory, which automatically presets receivable frequencies and station names simply by selecting a region. Manual input allows station naming up to 5 digits. It supports AM stereo broadcasting. It includes a 3-program advanced timer for weekly operation (ONCE, EVERY1, EVERY2). A clock display with reduced brightness shows the time when the power is off.

CD-alpa7 - CD player with 1-bit ΔΣ (delta-sigma) D/A converter. The ΔΣ method combines oversampling and noise shaping technologies with high-speed CMOS-LSI technology. While conventional DACs required extremely high element precision and stability, this DAC has the excellent advantage of eliminating distortion dependent on element precision, as long as a stable reference frequency is available. This achieves low-distortion, linear characteristics from large amplitude signals of 0dB to minute signals of -100dB. To reduce vibration and resonance during motor drive, a newly developed transparent resin material, used in the insulators of the AU-α series, is employed as a vibration countermeasure. Furthermore, materials with excellent vibration absorption capabilities are used at the contact points (mechanism base) between each mechanism and the chassis to block vibration transmission paths. It features an optical digital output terminal. It supports CARS PRO recording (high-quality synchronized recording function) when combined with the D-α7 cassette deck.

A-alpha7 - Integrated amplifier of the ALFA series that compactly condenses the technology of the AU-α series. In the A-α7, the combination of the diamond differential circuit and the Wilson current mirror circuit is collectively called the Advanced Diamond Differential Circuit. By incorporating the diamond differential circuit into the power amplifier, the power transistors (LAPT) in the final stage are driven with ample headroom, the signal rise characteristics are improved, and it can handle rapidly changing digital sources. In addition, the Wilson current mirror circuit is used in the first stage of the power amplifier to suppress circuit noise generated in the first stage and improve the overall quality of the amplifier. A twin-monaural power unit configuration is adopted to improve L/R separation, reduce crosstalk, and eliminate mutual interference between L/R. Power output 2x50W 8ohm.

S-alpha7 - Loudspeaker system. The low-frequency range is handled by a 16.5cm cone-type woofer.

The diaphragm is made of non-pressed coniferous pulp material. The high frequencies are handled by a 2.5cm soft dome tweeter. The diaphragm is a 100% silk soft dome. An aluminum die-cast frame is used for the tweeter mounting. The enclosure is a bass reflex structure with a port on the rear. 

The baffle plate is made of high-density MDF and combined with 30mm thick side panels.

Accuphase E-202 (1974) | Kensonic Laboratory

 

The Accuphase E-202 was a classic high-end integrated amplifier from 1974 that delivers 100 watts per channel into 8 ohms with both channels driven, maintaining less than 0.1% distortion across the full 20 Hz–20 kHz range. Developed using the advanced engineering principles of the Accuphase P-300 power amplifier and Accuphase C-200 control center, the E-202 combines separate-component performance with the convenience of an integrated design. Its robust parallel push-pull output stage, oversized power transformer, and massive 20,000 µF filter capacitors ensure exceptional dynamic headroom and stable power delivery, allowing the amplifier to reproduce both powerful musical peaks and delicate low-level passages with remarkable clarity. A distinctive Speaker Damping Control lets users select three damping factors to optimize the amplifier–speaker interaction and reveal the full tonal character of virtually any loudspeaker. Additional highlights include dual power output meters, a high-linearity phono equalizer with selectable cartridge impedance, subsonic filtering, precision tone controls, multiple tape deck connections, and comprehensive protection circuitry—making the Accuphase E-202 a legendary vintage audiophile integrated amplifier known for its clean, detailed sound at any listening level. Specifications: 2x100W RMS 8ohm | THD 0,15% 8ohm | Dimensions (W/H/D) 455x152x355mm | Weight 19,5kg | Original sale price in Germany 2450 DM (In 1972, brothers Nakaichi and Jiro Kasuga left Trio-Kenwood corporation to form a separate company. This was Kensonic Laboratory, releasing products under the brand name Accuphase.)

TEAC V-970X (1988) | 3 head cassette deck

 

The V-970X is one of the finest examples of TEAC's leading position in tape recording technology. The three-motor drive uses IC logic control, resulting in quiet operation. The highly precise dual-capstan configuration reduces modulation noise and wow and flutter. The precision three-head playback system adds nothing to the original. The TEAC Servo Control System (HTSC) monitors smooth operation and tape tension. Hysteresis tape tension control system developed for the first time worldwide by TEAC engineers. While automatically controlled tape tension systems are widely used in professional recorders and high-end reel-to-reel tape recorders due to their precision and reliability, it took TEAC's foresight and technical expertise to apply this development to cassette recorders. Other distinctive TEAC cassette recorder features include bipolar power supplies to ensure absolute accuracy in signal transmission, bias calibration controls, and the use of amorphous cobalt alloys in the recording and playback heads—another technology first developed for professional use. For greater ease of use, TEAC offered a selection of proven noise reduction systems — Dolby B, Dolby C, and dbx but also Dolby HX Pro for further signal enhancement and increased headroom. The amorphous cobalt three-head system enables optimal recording and playback heads and allows real-time monitoring during recording. Specifications: 3-head system, LC-OFC cobalt amorphous recording and playback head, double-gap ferrite erase head | 2+1 motor system, 1-DC capstan, 1-DC reel, 1-DC servo | Wow and Flutter 0,025% (WRMS) | Frequency response 20-21.000Hz Metal, 20-20.000Hz chrome, 20-18.000Hz normal | Dimensions (W/H/D) 471x124x280mm | Weight 6,6kg | Wireless remote control RC-311 | Original sale price in Germany 1450 DM
