I doubled the DXE's between my router and etherregen to four DXE's.

 

I like it.  Sound is fuller, rounder, more analogue, obviously a bit less crisp- but more natural.  It may work.  Not sure yet.

Do you use any audiophile ethernet wire between DXE's on that position, or only supplied 6 inch ethernet pigtails?

BJC ethernet cable.

 

By the way- all four DXE's together one after the other don't sound nearly as good to me as two near the router and two near my PC- much better detail..

I'm sorry to be a naysayer here, but my experience inserting DXEs after EtherRegen and a Cisco 2960 switch, and before a long run of CAT5e through the walls past all kinds of devices, and then the other piece installed before a second Cisco switch gave me reduced dynamics compared to no filters. Suggestions?

 

I will now try these on a different, long CAT5e run to an Allo USBridge for my Audeze headphones before I rule them out.

An experiment with the copper ethernet cable after the eR (and directly to the DAC) suggested that in my system this last leg is critical (significantly upgrading the ethernet cable made a large positive difference in SQ).    If that can be generalized (perhaps not), then one needs to be careful about what follows the eR (meaning, don't muck it up).  Just one system and one data point.  

I found that any STP Ethernet cables didn't work *anywhere* in the chain. The sound was very rough. What does work is to wire power supplies so that at the load and source connector's shells, a measurement of 0.000V between the + of the PSU is important. IF an STP is introduced, that near perfect zero starts to climb 😕

I am using 7 ethernet wires on my digital chain with DXEs with positive results.They are different quality from no name cat5 to audiophile ethernet wires. Best results was got installed on Sablon Audio ethernet wires right before and after Ether Regen.

 

What it is your digital chain? I am suggest to you use your EtherRegen on position last device before your music player, renderer, endpoint, or ethernet DAC, especialy if you powering yours Cisco switches with their internal noisy switching power supplies.

Thank you for tip to Monoprice SlimRun Cat6 Ethernet Patch Cables, will tray them soon.

Finally replaced the CAT7 pigtails supplied with the DXE with bog standard CAT5e cables a little shorter about 5cm (2") less. The original pigtails are a shielded design. Still getting used to the sound, but certainly is not worse.

 

With yesterday's network cable interruption, the EtherRegen is now playing up a day later, with the Lumin U1 displaying a network error. Just needs a power cycle to the ER and the Lumin and DAC off, wait a while, then power up the Lumin and the DAC in that order.

Don't know why, but I find that it takes a new CAT cable time to settle in, even if it has been used but out of the system for a while.  Am curious about how your experiment turns out.

I really would like to invest in boutique cables, but the Wireworld, Nordost and some Audioquest are all shielded designs. Tried shielded even with a parallel ground wire and results are not good :(. Tried a few more sessions earlier on, promising!

doesn't Ghent audio utilize the design John suggested for copper ethernet?  My not be boutique, but always well built and uses quality materials.

What matters is whether or not the shield is tied to the metal end shell at both ends.  One can not know just by looking at the cable. For example, the Audioquest cables, even though they have metal end shells and a shield, they only tie the shield at one end—and that’s good.

Taking a continuity test meter to the cable is the only way to know for sure.

That's all and good, but am not prepared to spend USD450 on a cable that's shielded at both ends the hard way. I guess I have to nag manufacturers direct as none specify how the shields are connected. Audioquest has the direction arrow, only convenient when connecting to the EtherRegen,  so you know which cable is A or B.

Hmm, the Ethernet cables are also shielded from Ghent,  even the plugs are metal. 

My assumption was based upon this part of the Ghent description, with a link back to John's discussion about shielding, meant that Ghent had followed John's advice:   Linkway CAT8 S/FTP 40Gbps Ethernet Cable with JSSG360 Dual-shielding protection, designed for Audio quality

 

The JSSG360 link leads to a page on AS where John writes:  So some ramifications of this: The traditional "connect the shield to one end and let the other end float" is not good, it does not allow a loop so shielding does not happen very well. If you add the external wire connected to the shield at both ends, then you CAN connect one or both sides of the shield to the signal ground or some other ground, but you don't NEED to for effective shielding. You will find that in many cases leaving the shield completely disconnected from the rest of the circuit is the best way to go, you get the benefit of properly working shielding without any interaction of the shield with your system. You may wind wind up with static charges on the shielding so a resistance from the shield to ground may be useful in some cases in order to dissipate static charges.

Mea Culpa. After replacing the supplied blue Ethernet pigtales with your recommended short & cheap monoprice UTP versions, and letting everything play for a day or two, l find that a pair of these DXEs do indeed provide a deeper background that reveals more detail. Quieter but tighter. Thanks.

 

I am also hearing more, bigger bass which is OK with me, but are we getting some kind of unnatural bottom end “bloom” with these cheap devices, or were the recordings originally made that way? OCD minds want to know…

My situation changed when I found that I prefer the ENO Ag cable and filter just before my best Roon network endpoint. ENO replaced the ER which then found a home after the optical segment that isolates my audio gear from the main Ubiquiti router and before three endpoints (primary system, secondary and headphone station), hence the Cisco switch to serve all three.

 

Yes, the switch is AC powered but acceptable to me (or at least rationalized) through Shunyata cables and conditioning.

When I add a component/device to reduce noise, the settling-in process proceeds from bass to the higher frequencies and it usually takes a few weeks to be able to determine if they are all in balance.  Perhaps it will take a bit longer for you to find out in your system.  That said, you use the ENO and eR, so you have quite a few devices already.  You may not need the DXE filter or it may not work well in that setup.

So far, it’s been worthwhile using ER for all three endpoints through the Cisco switch. Hans B reported that positioning it before the ENO hurt his results, but I haven’t found that to be true.

 

I wish that someone would buy me another ENO. Barring that, a DXE pair at each end of those long inwall runs gives the other endpoints a decent lift for few dollars.

Why not ask the same guy/gal who bought the first one for you.  😉
