Or 5) Wait till Meridian releases a proper onboard solution.
My guess is they produced this box to keep their customer base happy and not to scare off potential customers. But really they rather would have waited untill the HDMI specs are up to their standards. Which I really do not understand, because ie. is the SP/DIF spec that great? This is where the high-end companies can make their difference !!!
Disagree entirely. You'll end up waiting for a long time. IMO, the HD621 is a very elegant solution which opens up downstream Meridian processing to *any* PCM source, not just a Meridian source. *Any*
While Meridian's processors need to contain analogue components (ADCs and DACs), feeding Gigahertz frequency digital into the same box is an idea fraught with problems. The fact that other manufacturers have done so is irrelevant.
There may come a day when Bob is not Technical Director and Meridian product decisions are made on purely marketing grounds. That will be a sad day.
