AKAI AM-2950 (1979) | DC Integrated Amplifier

 

The AM-2950, introduced by Akai in 1979, aims for perfect fidelity with a DC amplifier which faithfully amplifies the input signal with a minimum of distortion over an extremely wide range from ultra-low to 100kHz. The DC power amplifier section of the AM-2950 stereo integrated amplifier reproduces the input sound faithfully for a full, rich sound. The rated output power of 120 watts per channel is maintained by a single power supply transformer which delivers a performance equal to that of two separate ones. In the secondary stage, each channel has a separate power supply winding giving the performance which is the equal of two power supply transformers. In the pre-amplifier section, 5 tone control zones can be controlled with the graphic equalizer tone control system. Consequently, you can now minimize the effects of different equipment and kinds of room and finely adjust for a sound that caters to your personal tastes exactly.

TEAC V-9 (1981) | The Chameleon

 

The sound you get is only as good as the recording you make. So TEAC engineers have pulled all stops to create a cassette deck that helps you make the most distortion-free recordings you've ever heard. It's called the V-9. It all starts with the revolutionary new metering system. Color-coded, peak reading, incandescent lamps, the likes of which you've never seen. Bigger. Faster. Easier to read. Any level over O triggers a red lamp at the speed of light. So your eyes can tell you what your ears miss. And at the push of a button, you can set the metering system for metal tape. There's no more guess-work. Just crisp, clean, distortion-free recordings. Next, put Teac's transport through its paces. Three motors. Full IC logic. The softest, lightest, quickest transport controls you've ever touched. And a totally new technology that connects those controls directly to the motors to eliminate solenoids. It's fast, efficient, smooth, silent and extraordinarily reliable. From its silky smooth, damped cassette compartment, to its motorized head-loading system, the V-9 is a recordist's delight. A perfect match for the "ACE" components from Teac.

SONY SCD-DR1 (2004) - Super Audio CD Player

 

The SCD-DR1 was created to deliver the faithful playback quality of Super Audio CD, unique to the original sound, and to unleash the full potential of CD. It brings together the best of Sony's disc playback technology, cultivated over many years. A crystal-clear sound field that makes you feel as if you can see the performers swaying their bodies. A supple depiction that conveys the texture of each and every layer of instrument tone. The SCD-R1 uses a rigid mount that surpasses the typical floating mount method in pursuit of highly accurate signal reading. The base unit, which includes the optical pickup and drive motor, is fixed to a sturdy chassis. This blocks external vibrations and suppresses resonance caused by disc rotation. Discs are loaded using a tray-loading method with a newly developed loading mechanism. The disc tray is pulled horizontally into the body, then drops vertically to deliver the disc to the fixed base unit. This combines a mechanism that is as resistant to vibration as a top-loading method with smooth usability. A master clock is located close to both the digital output section and the D/A conversion section. By using the dedicated master clock depending on the situation, jitter is minimized. This improves the time axis precision of signal processing, achieving outstanding sound quality for both digital and analog outputs. In addition, the external input terminal is equipped with word sync, and by using an external clock, even more realistic sound can be reproduced. 

R-core transformer power supply. The power supply section not only separates the digital and analog systems, but also the servo system, each equipped with an R-core transformer. Voltage fluctuations in the servo system, which controls the movement of the pickup that reads the signal, can be mixed into the digital signal processing, causing distortion in the pulse waveform. This adverse effect has been eliminated to achieve clean digital signal output. In addition, the analog signal processing section blocks high-frequency noise from the digital and servo systems that enters through the power supply, resulting in low-noise, high-quality, stable sound quality. The chassis is highly rigid, combining a frame made from a machined aluminum block up to 15mm thick with beams (leaves) that secure the base unit. The width was set at 340mm to allow for optimal placement of the parts used and to take into consideration strength and vibration prevention. This size is unconventional for audio components and was conceived to improve sound quality. The digital output terminal is equipped with four systems: i.LINK terminal, optical, coaxial, and balanced digital. The i.LINK terminal output has a high transfer rate of up to 200Mbps, allowing for the transmission of Super Audio CD multi-channel DSD data with ease. Furthermore, it is compatible with H.A.T.S (High Quality Digital Audio Transmission System), further enhancing the appeal of Super Audio CD. Width 340 x Height 140 x Depth 465 mm (including maximum protrusions), Weight 18,5kg, Original sale price: $11,000
