Just a thought on 2 channel MRC. John has already shown that adding it to existing products would be very expensive, it's probably true that reducing the G68 down to 2 channel is also wasteful. FIR filters are miles more efficient when they are multi-channel. There's a good chance that a 2ch MRC implementation wouldn't cost a lot less. Of course if they were doing that in FPGA instead of a DSP, they'd get tonnes of filters and wouldn't need four chips! :-)

On the 518 - I was one of those concerned about bit-depth, and the answer that they're picking it up from the SPDIF stream is the best possible answer. Now your 24 bit wavs from your media server shouldn't get reduced down to a dithered 16 bit just because you had to set your source as such. John - how sure are you about this?

Personally, I appreciate Bob's candour in answering most of the questions. There aren't many technology companies that will give away as much as that. I'm really pleased that the G68 is h/w capable of >6ch, but a little worried about how far the statement of in-player decoding for HD formats goes.

Either way I think we're being given a valuable amount of insight. Do Lexicon do the same thing for their customers? (genuine question) There are a lot of us here who work for techy companies. How many of them would release roadmaps or architectural details in a public forum?

Thanks to Bob, John and all the posters!
