SE speakers / upgrades et al were marketed as essential for the best of MQA.

Prospective customers listened to a small number of MQA tracks from upgraded 818 source!

Difficult to understand the difference considered here relating to 818/808 upgrades.

What is stopping the release? Surely not just the availability of recorded material!
