I cannot offer you a magic cure for your 'bugs' i am afraid. But you must remember the few frustrated international audya users on sz that have complaints represent only a tiny% of the total number of owners. The majority of whom are perfectly happy.
The few problems we have experienced in the UK are handled directly with the customer by phone or in person and rarely via an internet forum. We also work very closeley with our retailers who keep in touch with each Audya user and inform them of updates. If we cannot help when a problem occurs we will email or telephone Ketron Italy, who will come back with an answer, either straight away or with a reply that they need to discuss with their engineers. Either way it is normally resolved within a few days.
But we only have the resources to do all of that with our own UK customers that have brought via our retail network.
