Obviously this was before Tidal effectively pulled the rug on MQA. The interest mainly appears to be in SCL6 (wireless lossless for headphones), in particular from their launch partner PSB (part of NAD). If I want lossless headphones I’ll use a cable, don’t need a new codec. I thought Qualcomm were introducing lossless Bluetooth with their Snapdragon hardware.
It appears Reiner put in about €400k to fund the Administration. Meanwhile, the Administrators have burnt most of the cash, running the business at £500/$600 per hour. Can’t see this lasting long.
