Musical Fidelity currently utilizes disc mechanisms from SUOS-HiFi for three of its new models, while a fourth model combines a SUOS servo with a tray-loading mechanism from an undisclosed supplier. Meanwhile, Marantz manages its own drive development, though the extent of its reliance on third-party production remains unclear. Two other manufacturers have opted not to disclose their optical drive suppliers.
Supply constraints have forced companies to halt production of specific hardware. PS Audio discontinued its PMG Super Audio CD Transport after D&M, the parent company of Marantz, stopped accepting external orders for optical drives. Although PS Audio purchased the remaining stock from D&M, the supply proved insufficient to sustain manufacturing.
Naim encountered similar difficulties with its Uniti Star model. The company was forced to seek alternative suppliers after its original manufacturer ceased production, only for the replacement partner to also stop making the necessary components. Both PS Audio and Naim have reserved their remaining inventory of optical drives exclusively for repair and replacement purposes.
The industry faces a significant challenge due to the limited number of companies capable of producing these specialized components. While Marantz designs its drives in-house, other firms find this approach difficult to implement. PS Audio CEO Paul McGowan stated that developing an internal optical disc reader exceeds the current technical capabilities of his company.
