There probably is, but it will be around the stability of the sender’s transport clock, perhaps time variation . On a spectrum Analyzer one could see some of the sidebands around the fundamental (and its harmonics) from the frequency modulation caused by noise.
A paper on clocking stability and its characterisation associated with transport streams. (Telecommunications, but most of the same principles apply with SPDIF I would say.)
Yep. If the Naim streamer didn’t duplicate DAC’s with my V1 that would have been the way to go initially for sure. That said, the opticalRendu was big leap forward from the micro 1.4 and I got a Roon lite model demo model for a great price. Lots of ways to steam, that’s for sure.
Thanks @Simon-in-Suffolk , but unfortunately that’s beyond my understanding. I guess I was hoping for something simple like a “Transport Clock Jitter Factor” value of 1-100. Appreciate the thought though, and I’m sure someone here will understand that.
Then there is the important cables between the transport and DAC. I have just ordered a pair of Wave Storm BNC cables to go between my Mscaler and TT2. These are supposed to eliminate all the RFI noise between the two components. Some people use battery packs in place of power supplies, but I don’t want to mess around with those. The problem (for me) with the Naim streamers is they all have DACS on-board. If you use a seperate DAC like me (Chord), you are wasting the DAC in the (ND5XS2) for example.
I like the way the Auralic G1/2 and DCS bridge are streamers only, no wasted DAC on-board, if you use a standalone DAC. I have also been eyeballing the Simaudio Mind 2 network player, which has no on-board DAC, is made in Canada, and is half the price of the other two I listed.The dual BNC’s I have coming have 20 solid core ferrites per cable. You can also use them as a single cable, if that is all you need.
Careful… they definitely don’t and can’t possibly stop all the RFI noise!
What they can do is add resistive impedance to any common mode HF currents flowing across the ground shield of the coax. That is all. Still worthwhile, especially if the connections terminations are causing reflections, or one ground plane has noise compared to true ground with respect to the connecting ground plane… although less significant if galvanically isolated, unless there is HF capacitive coupling across the galvanic isolation. They also help keep down any stray coupled noise, which is why I use ferrite clamps, but in such a circumstance I use a single clamp at one or both ends right by either termination.
I just wouldn’t want anyone to assume they did something they don’t possibly having read some over exuberant advertising,
Ferrite clamps are a common EMC control, but typically at each or one end of the cable.
That seems like an odd choice, given that most hires material is released in 24/96 or 24/192. Apart from some (but not all) Qobuz streams, I can’t see it helping many people to access their hires music libraries in any useful way.
Thanks. Good to know. I guess it makes sense otherwise Naim would probably have a separate network bridge/ DAC combo instead of seemingly pulling out of the DAC only market. I’ll have to look for improvements elsewhere then, first off for me will be to try relocate my speakers followed by a bit of Roon room correction whilst waiting for a 272 successor to arrive.
