I liked the sound with the Cable Matters Cat 8. But there was also something from the Monoprice Cat 6a cables, perhaps a bit of intimacy in the musical presentation, that I missed. So I thought that since the Monoprice Cat 8 cables are quite inexpensive, I'd give them a try to see if I might achieve the best of both worlds. With the Monoprice Cat 8 I immediately felt the sense of intimacy had returned, without the defect of the Cat 6a in comparison to the Cable Matters, which is that the Cable Matters had done such a nice job of presenting top end and voices. The Monoprice Cat 8 in my system does a very nice job of that.

 

 

By "intimacy" do you mean a greater sense of being in the same room as the musicians?

Thanks to the photo you shared in PM, I was able to split the duplex connector.  I’m hoping I placed the attenuator in the Rx side.

 

There’s a $25 optical power meter on Amazon.  I may buy it.

For anyone interested in doing this, note the white wrap is on different sides on the two ends.  I got this backwards initially.

Any change in sound doing it this way?

I’m at a work event tonight so didn’t get much of a chance to listen, but after first sitting down there was an apparent difference.  A bit of the hot treble had returned which had me thinking I put the attenuators on the wrong side.  A quick Google search confirmed that to be the case so I swapped them and the hot treble was gone.  I really wish it hadn’t been so easy to hear the difference.

 

It did seem like the sound was more transparent with the attenuators used incorrectly.  It’s unfortunate the treble can get hot. Right before I left, I swapped in 5 dB attenuators.  I heard a difference but need to spend more time with it to figure things out.

Yes, that’s the result. I’d like to avoid using frequency-based terms because that’s really more appropriate for analog. But we haven’t developed very precise language for digital even after 35 years (quick, what does jitter sound like?), so I’m searching for necessarily imprecise terms that will convey how I feel when I’m listening, more than actually describing the sound itself. I listened to a song from an older Alison Krauss album a day or two ago, and I swear I could picture her bee-stung lips moving to form the words.


I will have to order one of these cables myself.  Thanks for sharing your observations.

From fiber back to inexpensive copper:

The Monoprice Cat 8 in my system does a very nice job of that.

 

Everything sounded so nice I thought I'd try to make it even better, so I did some experiments with moving power plugs around and bringing back an old MIT Z-1 into the system while I turned the volume up with no music and listened for noise at the speakers. When noise was at an absolute minimum I put the music back on, and I'm tremendously pleased.


Hi JUD,

very interesting, did you have tried the supra cat8?

Some findings about upstream changes:

 

My modem/router (made mandatory by my internet provider Ziggo, here in The Netherlands, a Compal CH7465LG) never seemed a very audiophile part in the chain. In forums and tests I’ve read a lot of times that the modem doesn’t play a roll in sound quality. That’s why I never experimented with it. It only has an iFi iPurifier2 after its SMPS, since a year or so. I can’t remember having heard any effect on the sound.

Because my sBooster LPS on ER did not give a good result (slightly less resolution), I had plans to sell it. But then I came up with the (at that moment seemingly silly) idea of trying it on the Compal. Immediately audible result in resolution! My wife heard it right away when she came into the room. Was it better? Unlike my wife, I like higher resolution in general, but I also found the high tones a bit sharp at the edges (test: Chet Baker, “Chet”: Alone together, both the trumpet and the saxophone). No matter the judgement, what is very clear is that modem (so "upstream") does have an effect in my system. To me that is, or rather was surprising.

Having determined this, I bought a decent cable from the “wall” to the Compal: I went from a 1.99 euros standard cable provided by Ziggo to a better, but still very cheap, Clicktronic f-connector coax cable (13.99 euros, just the most expensive Ziggo-approved cable I could find). The sharpness disappeared, immediately audible, the soundstage even widened a bit more. These may be fairly unusual findings, but I would recommend and encourage anyone to experiment upstream in the chain. Happy listening!

Nope. Can't try everything. 🙂

Actually not surprising. While the ER certainly seems to help mightily with what's coming through the Ethernet cable, remember noise can come from the power side of the system. While Uptone's SMPS has a ground shunt to get rid of noise, this may not be the case with upstream modems, for example. This is possibly why I think my system did not sound as good with a Cisco switch feeding the ER via optical, versus the ER on its own - the Cisco was being powered by its internal SMPS.

I played with a Cisco Meraki 220-8 this week, tried it as an « audiophile switch » and results are pretty bad with the internal smps (upfront sound, warm and simplified). With or without an other audiophile switch in the chain this kind of choice show how smps can corrupt network audio results. Removing the internal smps for a LPS1.2 was a big upgrade for this Meraki, with qualities than can be reported with a good audiophile switch, except it still lose some good meat on the bone at the end.
