Ethernet cables

Clearly, For  us it is clear where the differences come from: shielding, shielding, shielding.

+1. Agreed. I use Supra CAT 8.1  as short endpoint cables between my FMC's  + a double shield around the cable configured in a JSSG 360 loop does the trick. Some Techflex around it, and done. Ethernet 'radiation' is hampering the rest of your system. Also, (possible) leakage currents between the components can be a reason ethernet cables 'sounds' different. (despite ethernet is transformer coupled). That is why (galvanic/medical) ethernet filters work. Your system is performing better, as a whole, due to better shielding and breaking of detrimental currents between components.

I would have never thought that they’d make a difference but yes they do! I use Wireworld starlight 8 s at the connection to my node and from my NAS to the network connection and love them. Highly recommended.

@vonhelmholtz As an experiment, I bought a pair of DX Engineering inline RFI/EMI filters.  I was instructed to place one on each end of the Blue Jeans Cat 6 line.  $50 for the pair.

I noticed an immediate openness and clarity..  It was actually eye opening.  They have been in there for a couple months.  I have no intention of removing them.  I also have no intention of trying several CAT cables because it requires fishing it through a suspended ceiling. The NA ENO and Etherregen are two other inline filters but cost much more.  I am not sure of the design but the ENO seems to be very popular.  There are many network switches out there also.  Some are based on the Bonn.  Open box pictures show others using this $300 switch and charging more.  The other brands might be upgraded versions of the Bonn, I don't know.  I have seen network switches priced anywhere from $70-$2500. 

It's just like all things audio.  If I'm happy with the sound, I don't need someone explaining all the theory and telling me I am wrong.  I look for cost effective and affordable improvement  There was another thread about this same subject in October.  It devolved into a name calling, post deleting mess. 

My experience tells me that streaming starts out as a good source of millions of songs, then there are several things that can be done to make it better. Lowering the noise floor is a big one.  You can move up the cost ladder with streamers but there are several low cost things you can do.

+1 on DXE. Also recommended: EMO EN-70HD galvanic isolator. Keep any connection after the last filter/Isolator to the DAC as short and high quality as possible. The final feet after clean-up have a large influence on outcomes

@soix you said you bought the WW Starlight 8 ethernet cable already, correct? What improvements did you hear over the generic cable?
Or is it still sealed and you are contemplating swapping it to a higher end cable?
