Todd, I know that asynchronous upsampling is a hobby horse of yours. I was prompted by your postings into talking about this with one of the senior engineers at dCS during my visit to them in January. Unfortunately my mathematical abilty is not sufficient to have fully understood what he told me but in brief he explained that even where the upsampled output is not a simple multiple of 44.1 it is still synchronous in the way that they do it. Please don't ask me to explain why as it lies beyond my competence but maybe you could ask them directly if you want the full story. Of course the current Purcell/Elgar combination allows for both "synchronous" and "asynchronous" upsampling. Interesting to compare them in practice given that all other factors are equal. Of course when using a word clock link between the boxes this effectively mandates the choice of a "synchronous" upsample rate.

"Unfortunately my mathematical abilty is not sufficient to have fully understood what he told me but in brief he explained that even where the upsampled output is not a simple multiple of 44.1 it is still synchronous in the way that they do it."Maybe it is the former case. If so, ASRC was dropped by the company that's been cited as being responsible for bringing it into the industry.
As of right now, to my knowledge, the only way industry has been able to properly merge high-rez to Redbook in a single entity is via the DSD bus. Too bad such products happen to be so damm expensive.
(And since I've never heard such a product, I cannot say whether or not this technology is the real deal.)
