The Adante situation reminds me a bit of a Pinball Machine from a few years ago - Pirates Of the Caribbean. It was discontinued shortly after release due to various issues including have to remove some innovative features that weren’t reliable, and was complex to build. It was under appreciated and the company’s next even more groundbreaking title was about to be announced, so dumb asses like myself waited and by the time People decided the Pirates was the machine to get, it was unavailable (except the stripped down feature version). Today the machine is considered the high water in pinball technology/mechanics and sells for close to double its original MSRP.
While I doubt the Adante will achieve such cult status, perhaps one day it will be more sought after than it is now. Funny thing is that pinball machines hold their value far better than audio gear.
