The additional reply and clarification from Bob Stuart is very welcome. It does at least show a willingness to take account of views expressed here, and to comment further. The threatened brick wall of further silence has been breached and that is very good news. I only hope that further constructive exchanges will take place.
Meridian is likely to view this forum as a site of continuous griping. They must feel that they can never do anything right: the HDMI solution of the HD621 was criticised for adding an extra box and reducing elegance; their introduction of new products and their adoption of new technologies is slated for being too slow; and the introduction of free apodising updates for 5k2s was soon followed by business (and complaints) as usual. And how many of the moaners have actually bought Meridian equipment new, and therefore directly helped the business? The inevitable conclusion is a feeling of anger, frustration, bitterness, cynicism and despair.
Forum members report poor quality control and slow responses to fix new equipment. They also see a long line of broken promises with regard to Trifield, upgradeability, firmware updates and suchlike. Equipment is difficlt to operate optimally because the handbooks do not include enough information with sufficient clarity, particularly when third party kit is added of a kind not made by Meridian (so the answer could not have been that a Meridian version should have been purchased). And being enthusiasts, they would welcome tweaking and operational tips from the people who know best: Meridian themselves. The inevitable conclusion is a feeling of anger, frustration, bitterness, cynicism and despair.
So, as has been said again and again, the solution is better communication. This is all so like a lover's tiff. We are all on the same side. Things could be so much better and happier. We can either communicate and grow together, or engage in emotional shouting matches and grow apart.
