The TechDAS Air Force IV turntable is a marvel of engineering, pushing the boundaries of what's possible with vinyl playback. It's a testament to the pursuit of audio perfection, offering a unique and captivating listening experience. This turntable isn't just a record player; it's a technological masterpiece that challenges conventional design and performance expectations.
What sets the Air Force IV apart is its innovative floating platter design. By utilizing a high-pressure air bearing and a vacuum hold-down system, it eliminates the microscopic irregularities that can cause distortion and interference. This results in a remarkable level of clarity and stability, allowing the cartridge to read the groove with minimal disruption. It's like giving analogue playback the precision often associated with digital systems, all while preserving the warm, organic character of vinyl.
The attention to detail is impressive. The platter, a single precision-machined piece of A5056 aluminium alloy, weighs a substantial 8.7kg, contributing to a low noise floor and improved dynamic expression. The chassis, carved from solid A5052 aluminium, adds to the overall weight, resulting in a sturdy and robust construction. The drive system, housed in a separate motor unit, is isolated from the main chassis to minimize vibration transfer, ensuring a clean and accurate playback.
Speed accuracy is achieved through a digital rotational control system, maintaining precision at both 33.3 and 45rpm with an astonishing wow and flutter of below 0.03%. The suspension feet, derived from higher-tier models, provide specialized damping to block external vibrations, further enhancing the overall stability. A tapered spindle corrects minor eccentricities, and a thin damping and antistatic pad protects the vinyl surface, ensuring optimal playback conditions.
Flexibility is a key feature, allowing enthusiasts to switch between tonearms and cartridges to suit their preferences or the record at hand. While no tonearm or cartridge is included, TechDAS offers compatible options, such as the Air Force 10 arm and moving-coil cartridges from Analog Relax, ensuring a wide range of sonic possibilities.
However, the TechDAS Air Force IV comes with a hefty price tag of £19,998 in the UK, making it an investment piece. But for audiophiles seeking the ultimate vinyl playback experience, it's a tempting proposition. The Air Force IV represents a significant leap forward in turntable technology, offering a level of performance and precision that sets a new standard in the world of analogue audio.
In my opinion, the Air Force IV is a testament to the endless pursuit of audio excellence. It challenges our perceptions of what's possible with vinyl, pushing the boundaries of sound reproduction. While it may not be for everyone, it's a fascinating glimpse into the future of analogue playback, where technology and artistry converge to create a truly immersive listening experience.
