Hmm, rather missing the point… this is nothing to do with Ethernet data, but more about the electronics that modulate the serial voltages and doing it in a way that minimises ANALOGUE conducted noise.
Several engineering white papers on this in the public domain including specialist analogue componentry to reduce conducted noise which this ‘audiophile’ product makes no mention of…
Now I agree in addressing this, just like Ethernet cables, one can throw money at the audiophile merchants, or simply get a quality suitable switch from the ‘bay for a few tens of pounds.
The area of proper Ethernet frame isolation interests me, and so far has not entered the audiophile market yet… but if you have good network routing and switching design and implementation skills you can achieve it with the right network equipment… and here we are talking routers, not L2 switches.
The alternate is to largely decouple Ethernet / digital transport from the DAC… at the system level a similar outcome can be achieved… and it’s the method I currently do.
hello, what kind of ethernet cables have you connected the time capsule to the modem router? me with a cat.6 but I’m thinking of replacing it with a Melco cat.7 ethernet cable
They recommend Cat6 in preference and claim their Cat5e and Cat6 sound the same, which is not at all what I found, preferring their Cat6, which is fuller, more textured and dynamic and more detailed. God knows why…
I give up… this has been explained more often than I have had hot dinners on this forum … and people still say ‘God knows why’… perhaps it’s easier if we just say it’s magic…
The Time Capsule is connected to my IP (Spark) router by a long run of internally wired (walls and ceiling) Cat 6 Ethernet cable. There’s no practical option to change that.
I have a ubiquiti set up including three switches, I wont be swapping them out any time soon for a perceived difference in the slight texture of a symbol or what ever.
If you want to enjoy your music more, get half cut and turn the volume up.
Thomas, perhaps you can explain what you are referring to with ‘Port based traffic control’?
Switches do port based traffic manage to of most frames.
There are however broadcast frames, ARP processing, and multicast group frames which can load the port irrespective of unicast data going to the specific host.
Creating a separate subnet from the rest of your network with the appropriate helpers and routing protocol support can reduce the above and consequential processing noise from the host (streamer) network stack and processor.
@Simon-in-Suffolk,…I understand you,.you have written hundreds of explanations on this.
So,.somewhere on the road you give up in the end.
But these “basic” questions will recur all the time,.this is due to the fact that there will be new members here.
• That is why I have suggested before,.that we should have a Music-system Installation-thread as “sticky”.
Then you do not have to repeat,.repeat and repeat the same thing all the time.
Because when you Simon,.and others with high competence in this field do not cope with writing anymore,well then a key knowledge source disappears for the forum members.
So Thank You Simon,.for that you still have the strength to write technical explanations about Cisco and other switches etc,etc…
