Cable suggestions

@wjcasey3rd for my digital side I have an Aurender W20 for my streaming source. Have an Aurender MC10 master clock to time it. But just changed from a Chord DAVE DAC to an MSB Reference DAC which has its own internal clock. 

Your Chord DAVE had its own internal clock as well, but you weren’t using it, and you won’t be using your new DAC’s internal clock either with AES EBU.

The DAC’s internal clock is used only with a USB connection. With the other connection types (e.g. SPDIF, AES EBU, I2S), your source’s (Aurender) internal clock is the master. If you did not notice any difference with the MC10 before, you probably won’t now either. 

It would be well worth your time to contact MSB about this for an opinion. They offer multiple input modules and make a big deal of their USB architecture performance, which is the only solution that makes the MSB DAC’s clock the master. Nobody here knows more about this DAC than they do.

Nice system....  really nice!

I went with AES between my Aurender N20 and my Berkely Audio Dac....using Shunyata Research Omega...it is a keeper. I talked to both Aurender and Berkely beforehand = both indicated AES was the way to go & both indicated the 2nd most important cable in your system...next to speakers.

I thought the MSB reference would buffer and reclock the incoming signal using its Femto clock, but I certainly agree it is worthwhile contacting MSB. You might also watch the latest edition of the HIFI 5 podcast wherein the MSB gurus were guests and this very point was addressed. The MSB guys are of the Ed Meitner school of thought that better performance is gained by having the clock as close as possible to the conversion function. They are not advocates of external clocks even though they could likely sell a bunch of them if they so chose.

MSB makes a roon ready streaming module you should be able to add to your DAC. I would Definitely test it against the Aurender to see if an outboard streamer is even necessary. 
As to cables, try AES and also try USB which will rely on your DAC clock. Use The Cable Company lending library and try different cables. 
I would add Audience and Kimber to the list for both AES and USB. 

Cables do not just create a particular voicing to a system, when carefully thought through at the Source end. Not only the Cable/Signal Wire but also the cable connector selected and the chassis connectors being used have a substantial impact on how the end sound can be discerned, with smearing being removed and the following attractive traits manifesting: Attack - Coherence - Dynamics - Micro Dynamics - Envelope - Timbre - Tone.

I heard a comparison of Two Identical Cables using PC Triple C, where one had the factory supplied connected exchanged for Copper low-eddy connectors. These Cables were used on two phon's, where one had a common Copper low-mass connector and the other a partnering Copper low-eddy connector as used on the cable.

The outcome has been indelible, and I can only say at the current time that recollection is allowing me to state the effect of the Copper low-eddy RCA's used on both cable and chassis was seemingly tangible for what was able to manifest and is, in my view, the presentation to aspire to.
