I see on the NPDT website, Dark Side of the Moon is for “SERIOUS AUDIOPHILES ONLY” and
“Price: 4300 Euros” that rules me out on both counts… :grin:

Saturday nights are still hectic, I hope to join you all soon…:crossed_fingers:t4:

Deliberately vague and trust me.

I’m not sure he’s even got the rights to distribute the material: Wall Of Shame | NPDT-Process©, but I think he’s shaming himself. I can’t see any evidence of a deal with a label, and he has very few releases, some very high profile. Absolute chancer would be my guess…

Hi Guys,

Dan Sullivan can’t post, I think he is not the right trust level, but, he sent me something to post for him on this this thread regarding the PS Audio air gap discussion.

===========================================================================

The galvanic iso in the PS audio server (and I think the DAC too) is an air gap implemented with a “digital lens”, i.e. a modulated light beam sent from one board to a light receiver on the another board. A transformer wouldn’t work in this case because it would not do much to block common mode noise in the system.

This is what Paul (I think) had to say about it:

The long-awaited PS Audio music server, Octave, is inching closer to making its debut in late 2019. Since I’ve not written much about it recently, I thought you’d enjoy an update about one of its innovations, a new invention called the Air Gap Audio Interface or AGAI.

The AGAI solves a big problem in digital audio servers, contamination by noise and electrical detritus. Inside a server, you have a noisy computer. As it chugs away at its tasks it jitters and pollutes the output signal feeding the DAC. This is why, we believe, FLAC sounds differently than WAV even though the bits are identical. A FLAC file (for example) requires far more bit crunching to extract the original bits than does a WAV file. Those crunched bits contaminate the final output signal through mutually shared power, ground and physical signal traces. How can we fix that? Imagine that the noisy computer inside the server was not in the server box and was instead far away (as we are doing in the upcoming Ted Smith Signature DAC). Its noise and ground contamination would not be a problem as long as we took its distant output and regenerated it in a Digital Lens. Since our goal is to build a one-box server, the next best thing is to physically isolate the two systems within a single chassis. To do that we need separate power supplies, ground planes, physical boards, and at the end of the proverbial day, a physically isolated connection between the internal computer and the output Digital Lens. That’s where the AGAI comes into play. By bridging the gap between the internal noisy computer and Digital Lens by nothing more than light traveling through air, we get excellent isolation. (In the upcoming TSS DAC the problem is solved with two chassis: a digital and analog separated too by light using a fiber optic cable between the two.) We’re all familiar with digital data transmitted through lightwaves using a TOSLINK cable but that won’t work for either of our applications because of TOSLINK’s bandwidth limitations. But that isn’t a show stopper. It just means we have to step up our use of technology. Some of the highest speed data in the world travel on beams of light. Whichever method is used, AGAI or high-speed fiber, transmission of digital data over lightwaves offers the possibility of getting noise and jitter out of the signal and gets us that much closer to musical perfection.

Dan

I’m glad I wasn’t on the call as if this was one of the discussion points it would have made me even grumpier than just reading about it does :rofl:
