Well, as it appears to me here, it is not so much that Graupner has lost their reputation, it is more the system (XPS) that they tried to sell so far.
Of course the reliability of the HOTT system has yet to be tested by users.
But, concerning the functionality, it is a 90% copy of Jeti (and it's price range(!!!)), and Jeti is currently the second most popular system after FASST here for a reason.
Add now to the functionality of Jeti, that the HOTT system comes already integrated in TXes, and is therefore suitable also for people, who lack the technical background or simply do not want to solder around in their TX...
Until now, Graupner had nothing that the average dealer could sell to a beginner, who wants a 2.4 set.
Concerning "pure dreams", these are actual reports from visitors of the fair:
