Implications of Esoteric G-0Rb atomic clock

Chris, I can't imagine how you could remove jitter from an existing digital recording as there's no inherent information that would allow you to determine the jitter in order to subtract it.

I think a bad digital recording is destined to remain a bad digital recording. However I hope to be proven wrong, because a lot of good music is otherwise beyond salvation.

Sean; the USB DAC that I have been citing does NOT connect to a CD transport, It connects directly to a computer i.e. my posts statements regarding the "hard drive" . With this methodology, the computer does not have a SPDIF (traditional) connection whatsoever. It streams pure data directly from the hard drive, WITHOUT the subsequent clock data. It is much different with this methodology. (It is also much more elegant). This is the ONLY way the sonic improvements that I am discussing can have any meaning. If there was a "traditional" CD transport involved, the USB carrying the data wouldn't yield any sonic improvements whatsoever (BTW: this is where your assumptions would be absolutely spot on). So, the complete elimination of having to carry clocking information from the CD transport to the DAC is where the huge jump factor relies (remember, the music data is now on a hard drive). With this in mind, any simplification of transferring the music data from point A to point B really does yield sonic wonders.

Drubin; Yes i have heard the Nova Physics player. I think it is an admirable attempt at solving many of CD issues. Like other offerings though, it is still a band-aid approach that doesn't simplify the transfer of music data as well as the USB approach . Again, the proof is in the pudding though. And this player doesn't actually stand at a complete different level above other UBER priced digital products. It is really good, yes. Revolutionary, well if so, then it should absolutely crush any other digital offering IMHO (which it doesn't achieve).

BTW: Even though my posts have been heavy handed technological discussions, I will always favor the digital product that sonically comes closest to a top level analog rig. IMHO way too many technological assumptions, WITHOUT direct comparison to a source of great music perfection (in my case, a great analog rig) are one of the reasons we are now accepting the crazy expensive digital mess and these inherent "band-aids".

Even if the best sounding digital front end turns out to be a Donkey spinning a CD, using a fifty cent flashlight, connected to an electronic slide rule, amplifying via a megaphone. If this "front end" truly sounds closer to a great analog rig, I'm buying it! ....and alot of Donkey food ;-)

This might answer all your questions.

I believe that the reactions of all the reviewers that first heard the Memory Player were NOT all hype. For Harry Pearson to say "He was in AWE" is huge. If his statement was hype, well he must be a "silent" investor in Nova Physics Group.

To be able to explain the shortcomings of the CD playback system and the approach they took to mitigate it is simply not a band aid approach, in my opinion.

Ehider,

Sounds like you are talking about a music server which utilizes USB because you mentioned streaming? If not, what about the playback software and EMI/RF issues with PC playback. These have a huge impact on sound. Will there be a special PC with this new USB wonder device? I thought music servers utilizing network protocols may have been the future?

I can't wait to replace my transport/dac with an HD based system. Seems like not much can beat the Meitner/Esoteric stuff yet, but it certainly seems close. Do you have experience with these transports and would you say this new device bests them? I hope so.

Rgt; I seriously applaud the Nova player designers. They are solving issues that most other digital solutions fail to address. I have no doubt that the Nova is very close to the "top of the heap" digital offerings at this point in time. Much closer to analog, absolutely. Close your eyes and absolutely match analog though, just a smidgent short (but the Nova is very special sonically IMHO). From a technical analysis, the USB solution (that sonically amazed me) avoids interleaving the clock data with the streaming digital information (as compared to the Nova and others). I should note that there are many similarities here with both the Nova and USB solutions. They both address the read error issues which I suspect are part of the sonic 'breakthrough" toward analog. I still hold the direct comparison to analog as my final "tool", i.e. the digital solution that comes closest to sounding like a great analog rig or a master tape deserves the "top of the heap" moniker.

Askat; I think you are correct to assume we need to watch out for EMI/RF issues in the computer. I myself was wary of sonic gremlins associated with a computer's hard drive as the digital transport. Thankfully, the potential problematic gremlins seemed to be entirely absent when I heard the computer to USB DAC solution. (The computer was a current generation Apple computer with the CDs transferred to the computer's hard drive via Apple's internal error correction enabled). Are Apple computers inherently low EMI/RF designs? I have no idea. I do know that the particular Apple to USB DAC was the best digital solution that I've ever heard in terms of managing to sonically emulate a great analog front end.
