Thank you all for such informative posts and sharing. I will learn to do the subwoofer crawl, though the dealer needs the demo unit back this weekend. Being a demo unit I dunno if the firmware is up to date. How do I check the firmware status ?

The lapse of time and the MQA compatibility lead me to believe a refresh is sooner rather than further away. The unit can also benefit from miniaturization since its release at least 4-5 years back.

I will miss it for the time being but the $$$ are better spent on a future proof solution.
