Shielded Cat yep as that would help to reduce any external EMI getting on to the cable and thus into the ID40, thus use a ferite cores could be an advantage as well. However, I don't see any advantage in using SpeakerLink cable for network connections.

Yep, and then this PCM packet data is buffered in the ID40 card and clocked directly on to the 861v6's internal bus.

No, I would expect it to be the same with MS600 receiving PCM packet data from the core just like the ID40/ID41 cards.

Thanks, Carl. I keep learning--and I very much want to understand how it all works. Appreciate the edit assistance as well--still figuring out how to manage the forum editor as well.

If this description of what happens is accurate, it still (apparently) yields better sound than a C15, Twinstore, MS600, where I presume the FLAC-->PCM conversion is handled at the endpoint? Just 'logically' that seems odd to me, though I know there are many other variables in the picture.
In BOTH the above systems, with either an ID40 or MS600 as the Endpoint.........the Core is doing the FLAC to PCM Decode........and sending the PCM Data as inherently jitter free data packets, which can be reassembled in a jitter free way at the Endpoint, as the Endpoint knows the Timing of each of the Data Packets........which is not the case with PCM over SPDIF, hence Jitter.

The Endpoint always seems to receive PCM Data over IP.........so there isn't the difference you propose above between the ID40 and MS600.

Hi Jerry,

Our understanding evolves over time; I too thought that the Sooloos endpoints (ID40, MS600 etc) decoded FLAC to PCM till recently (thanks to Duncan).

So we now 'know' that it is the Core (where ever that function is situated) that does the decoding to PCM data.

Regards,
Carl

So with all of these packets moving back and forth on one's home network, is there any (theoretical?) advantage to hanging a dedicated, separate switch off of the main router just to handle the various Sooloos components?

Have a look here it discusses the question you raise.

Sorry to be off topic but I just read through that thread, which I started. First, I am amazed at what a great online community this is as there are so many knowledgeable people who are willing to help. Second I realize how bad my dealer was who sold me the C15. Had no clue. Since then, thanks to this site, I have a real dealer who knows all about M and is willing to go the extra mile to help a customer out.

A bit more on topic. Since those early days I have installed managed business class switches on my LAN in an abundance of caution. They have much more processing power and have a variety of other useful, but not absolutely necessary, features.
