I cannot help, but curiosity made me ask my browser (brave, no pop-ups) and these are the AI quickies I got, others with direct knowledge of them can add to this I imagine.
Mitchell
The Michell TecnoDec is an entry-level reference turntable from Michell Engineering that incorporates high-end technologies typically found in more expensive models, such as the GyroDec. It features an unsuspended solid-plinth design with Pure Sorbothane feet for vibration isolation, an impedance-matched platter for neutral sound characteristics, and a free-standing motor unit machined from aircraft-grade aluminum to minimize vibration transfer via the drive belt alone.
Key technical specifications and features include:
-
Inverted Oil Circulating Main Bearing: Uses a modified Archimedean screw to draw oil from a base reservoir to the top thrust ball, ensuring continuous lubrication and reduced noise.
-
Tonearm Options: Typically equipped with the Michell T2 tonearm (based on Rega designs) or available with Technoarm/Origin Live options; cartridges are often sold separately or in packages.
-
Dimensions: 49cm width, 31cm depth, 8.5cm height, and 4.6kg weight.
-
Price: Retail prices generally range from $2,200 to $2,600 USD or £2,000 GBP, depending on the bundle and retailer.
The turntable is designed for minimal setup and maintenance, offering a low noise floor and high musicality, positioning it as a formidable performer and significant value in the high-end vinyl market.
Acoustic
The Acoustic Signature Primus is the German manufacturer’s entry-level belt-drive turntable, designed to deliver high-end performance with Teutonic Engineering precision. It features a heavy 4.5 kg aluminum platter mounted on a proprietary Tidorfolon bearing (backed by a 10-year warranty) and is driven by a DC motor with an external power supply for stability.
The turntable is available in two main configurations:
-
With RB 202 Tonearm: A modified British tonearm paired with an Ortofon 2M Red cartridge, originally launched at an RRP of £1295.
-
With TA-500 Tonearm: Acoustic Signature’s first fully in-house tonearm, featuring a dual carbon tube for superior damping and stiffness.
Constructed from a rigid MDF and chipwood sandwich chassis, the Primus focuses on mechanical quality over gimmicks. While it was a popular model for audiophiles seeking German build quality at an accessible price point, it is now classified as a discontinued product and is primarily available on the secondary market or through remaining stock retailers.
