ONKYO TA-6711 (1997) | Integra High-Performance

 

The Onkyo TA-6711 from 1997 was one of the last "high-performance" cassette recorders ever manufactured. It was a high-performance 3-head cassette deck engineered for those seeking true professional recording quality in a home audio component. Its precision three-motor transport incorporated a regulated dual-capstan drive with full electronic logic control, maintaining optimal tape tension and ensuring constant head-to-tape contact across the entire cassette for exceptional speed stability, reduced wow and flutter, and superior sonic accuracy. The advanced linear-glide loading mechanism, combined with a dedicated cassette stabilizer, secured the tape firmly in place while minimizing vibration and mechanical resonance. Separate record and playback heads, each optimized for its specific function, along with a dedicated erase head, allow real-time monitoring and enhanced recording precision, while high-grade PC-OCC head cabling preserves signal purity. A discrete ultra-low-impedance linear switching power supply, partnered with a high-quality shielded AEI transformer, reduces electromagnetic interference and safeguards audio integrity. Onkyo’s fully automatic Accubias system automatically calibrates recording parameters to match the selected tape formulation, with manual adjustment available for fine-tuning to personal preference. Additional features include Dolby HX Pro headroom extension, Dolby B and C noise reduction, independent level and balance controls, CD synchronized recording, automatic tape type selection, switchable MPX filter, real-time tape counter, forward and reverse music search, a large 5-segment FL display with dual 24-segment peak level meters and peak memory, front-mounted microphone inputs for left and right channels, and a resonance-resistant stamped steel chassis, making the TA-6711 a highly capable and audiophile-grade vintage cassette deck. Specifications: 3-head system, Hard Permalloy | 2+1 Motor mechanism | Wow & Flutter 0,045% WRMS | Frequency response 20-20.000 Hz Metal tape | Dimensions (W/H/D) 435x131x370mm | Weight 7,2kg

AKAI GX-4000DB (1981)

 

The story of THE 4000 series from Akai dates back to 1975 which in turn was an upgraded version of a model introduced in the mid 60s. THE 4000 model range is probably the most recognisable basic open reel deck in history. After countless revisions and upgrades the final version GX-4000D remained in production until the mid 80s. One of this versions was the GX-4000DB shown here that included Dolby noise reduction.

DUAL CS 627 Q (1981)

 

The Dual CS 627 Q is a fully automatic, Quartz-PLL direct-drive turntable introduced in June 1981, representing Dual’s advanced engineering direction of the early 1980s. Available in elegant Satin Metallic finish, the CS 627 Q was housed in the company’s specially developed HDC (High Damping Compound) plinth, designed to minimize structural resonance and external vibration. Four integrated, height-adjustable shock-absorbing feet further enhance isolation and stability. At its core lies the electronically controlled EDS 502 direct-drive motor, governed by Quartz PLL speed stabilization for exceptional rotational accuracy. When Quartz lock is disengaged, the turntable offers a generous ±11% variable pitch control, allowing precise speed adjustment. The CS 627 Q was factory-equipped with the Ortofon TKS 55 E cartridge featuring an elliptical stylus, mounted in Dual’s newly developed U.L.M. (Ultra Low Mass) tonearm system. This ultra-light arm design minimizes....
