Being a former Ref 50 owner and watching them since the Ref 10 I thought I would comment for those of you holding off for the Ref 70.
This whole dialog is VERY familiar. Us B&K supporters waited, and waited, and waited for DPLII. Every month or so someone would call them, "Almost there, need to wait for Motorola, we won't do it until we are happy with the implementation etc. etc." Then it happened with DPLIIx... B&K came out YEARS later than most others BUT with a solid product with the best support of any manufacturer I have ever dealt with. Let's just say that to be a B&K supporter you need to be patient
So 1.5 years ago I was looking for a solution to accept lossless audio over HDMI and be able to run PS3, HD-A2 and HD DVR with one input to my TV. I knew better than to wait for B&K. I settled on the aging Yamaha 2600 as a pre/pro and couldn't be happier. Lossless audio can sound much better with the correct source and, as some have mentioned here, is now becoming more forgiving of the processor. Ease of use, way better than the B&K. I was also delighted to find that analog audio didn't suffer either (note I recommend you perform a genuinely blind test on this one no matter what you think from memory). This shocked me but my wallet has never been happier.
I am surprised to hear people referring to those many people with HDMI/lossless audio implementations now, whether it be receiver or pre/pro, as 'early adopters'. You need to face facts, B&K is late, AS USUAL. If you want it, it's out there for the taking. I have a 3 year old receiver that can be bought at rock bottom blow out prices that handles HDMI from many sources with aplomb - zero issues.
No doubt that B&K's product will be a great one once released and can certainly understand people holding off waiting to support such a great company. But don't kid yourselves --> B&K's typically conservative adoption delays mean you will be years later than most if you wait for them...
