gregmav,
I might be wrong about this, but I think the term 'coax' as used here means the single digital input which uses a single RCA-type female socket. Hope this answers your question.

Cheers,

Mark

PS- I enjoy my Insight DAC, but "they will have my vinyl when they pry my albums from my cold, dead, hands". Franks phono stage is excellent, too !!

Coax means RCA jack connections, although these can be changed to BNC on a special order basis, or even XLR balanced line out, again an extra cost option.

RMAF went way too fast! Both the Salk speaker rooms were clear cases for Jim's speakers. :thumb:

I have been busy since returning. Will post some pix later.

Not seen often but a real show stopper is the ritual break-in dance done each time a component is turned on.  :lol:


I'm sure this Ring Around the Rack dance will be all the rage now that our cameras have captured this rarity for all to see. :rotflmao: :rotflmao:

Okay...  I'm trying to come up with the proper tune here... Meters, Neville Bros, Wild Magnolias, Dirty Dozen Brass Band?  Come on all you funk meisters out there, help me out.  GOT to have some Second Line in it, though...

And still photos are definitely good, but we need VIDEO!!!

"Come on and do it, do it, do it 'till you're satisfied. Whatever it is!"

And if we get everything right it will, oddly enough, make relevant comments I made today in another context regarding the origins of the button flap seen on the back of long underwear in cartoons of a certain vintage.  I would paraphrase, but that would be veering severely off topic.

Oh, what the hey, it's almost November, the dancers are back home:

"..  the TRULY significant concern about the issue which you raise  is not about nomenclature, but rather pertains to the obvious purpose of said 'thingy'.  There are two things to consider here.   First, one must recognize the first signs of the onset of the phenomenon which prompted the original inventor/designer to make the flap in the first place.  And THEN, just as importantly, if not more so, one must know what to do with the ensuing products.  This raises other concerns and issues which are all considerably above all our pay grades.  As an aside (AKA "sidebar", for those of the judicial or legal persuasion), in certain parts of the Ozarks, on either side of the MO/AR line, this device is most often found useful in the "Bend over, have I got a surprise for YOU!" ruse..."

This might actually be relevant in the thread about tubes and quarks and the expanding tube theory...

At RMAF we are playing SACD 96K 24bit material after de-embedding it from the HDMI ouput of our OPPO blu ray player with an Atlona 577 and feeding the digital audio into our Vision Hybrid DAC. 

I'm not sure I understand this.  The SACD format is 1 bit DSD, 2.8224 MHz sampling rate, not 24 bit PCM, 96 KHz.  Is it being converted to PCM in the OPPO player or the Atlona de-embedder?  Or, are you actually referring to DVD-Audio?

When Oppo plays a SAC disc the DSD signal is is available through the HDMI connection.  The Atlona de-embeds the DSD signal and sends it to our Vision DAC.  The Wolfson 8742 chip reads the DSD signal and our DAC outputs an analog 2 channel stereo signal.

Frank looks a hi bit rate signals as kind of one thing and doesn't dififferentiate between PCM and DSD because our DAC reads both.

You can check the Oppo's specs, the (audio) formats available through the HDMI connection are listed.

Sorry for any confusion.

Dean

Thanks for the clarification, Dean.  I was aware that the Wolfson 8742 processes DSD but I wasn't sure if the Atlona could de-embed it like PCM (read somewhere there were DRM reasons care of our buddies - Sony/Phillips).

Is there any possibility of your DAC getting HDMI inputs, eliminating the need for the Atlona?  I know it would be a significant cost increase, but should be less than buying a de-embedder.

I don't think we will any time soon. 

Jim Salk and Frank were looking for quick way to play Hi-Res materal without Jim redoing his great music library for RMAF 2010.

Hi Dean,

Does the Oppo (BDP-83 I'm guessing) send DSD material to the Atlona or is it being converted to 24/88.2 PCM by the Oppo first which is de-embedded by the Atlona and then sent to the Vision DAC?  I don't believe it is DSD that is being passed through.  I may be wrong but that is what has been posted on other forums, of course they weren't using AVA gear though.

Just Curious,

The Oppo BDP-93 can be set to transmit native DSD or convert to PCM (up to 192 KHz) through HDMI output when playing SACD.

Researching the Atlona HD577 specs for audio de-embedding from HDMI, I found:

"Dolby Digital, DTS, DVD-Audio, LPCM, SACD, MPCM [de-embedded]"

It appears that the Oppo can send the native DSD stream from SACD via HDMI, the Atlona can de-embed it for the Vision DAC, and the Wolfson 8742 chip can process DSD directly.

And, after doing all that, no one can hear much difference from the Red Book layer of the same recording....

Thanks  for the response.  I had heard of many people using the Atlona to de-embed Hi-Rez from SACD but all the stories told of converting to PCM in the Oppo first.  I had no idea that the native DSD data from the SACD can be transmitted to the Vision DAC.  Another very good reason to pick one up... but maybe I won't hear the difference.  ;^)
