The big question is: how do different db attenuators sound, and would a better quality attenuator (say a Belkin) sound any better? Also, both ends vs just the receiving one? I’ve been going through the same thought process. I’m still using 10 dB on one side and 5 dB on the other. I really like where this has landed .. though another pair of 10 dB attenuators is now 6 stops away. It’s really easy to A/B copper vs fiber here now. All I have to do is change which cable plugs into the wall outlet. (This is a choice between a 8m span of fiber or 7m span of Wireworld Chroma from wall jack to EtherRegen) Copper almost seems watered down relative to fiber - as if water was added to a really good Cabernet. Fiber delivers all the flavor via greater coherence, focus and density. The improvements are musically important for sure. The fiber brings some other improvements too, but the aforementioned were most obvious when doing A/B.

charlesphoto Posted January 19, 2020 Share Posted January 19, 2020 @kennyb123 Let me know how those extra db work for you. So you're saying you have attenuators on both ends of the cable, or just one end and different values for each side?

If so that means I now have a total of 15 dB of attenuation applied, with 10 dB applied to both legs on the server side (the ER) and 5 dB applied to both legs on the other side. I will experiment with a number of combinations and report back.

KunterK Posted January 20, 2020 Share Posted January 20, 2020 Has anyone tried fiber attenuators with TP-Link 311LS? Startech has 80km which should be happier with attenuation, but TP-Link also has a 10km range? A good single mode cable has attenuation of 0.2 - 0.4 db per km so 1db attenuation simulates 2.5 to 5km of cable. I now have Startech and TP-Link to play around and do comparisons. Startech without attenuators is boringly correct (if there is such a thing) so I am eagerly waiting for some attenuators to arrive. Also the fiber cable makes some difference in performance. I had locally sourced SM cables and the ones I received from Amazon (sold by H!Fiber.com sound better to my ears. They should not let us audiophiles near these things!

Mike Rubin Posted January 20, 2020 Share Posted January 20, 2020 I think I get where this thread is going, but please allow me to make sure I get this. If your optical connection is too short, you run the risk of overloading the receiver FMC if you don't use attenuators? If so, how short is "too short" before this becomes an issue? I currently am running one meter optical cables. I am skeptical that I we would hear enough of a difference for me to invest a lot of time sorting out five versus seven versus ten db, but I am very concerned about overheating the FMC's in my optical Signature Rendu SE and the opticalModule that feeds my ultraRendu. The possibility of shortening their lives scares me.

sahmen Posted January 20, 2020 Share Posted January 20, 2020 Is there an option to try the optical connection without needing to bother with any attenuators? I currently have the ER deployed between an Asus Router and a Metrum Acoustics Ambre, and the system sounds pretty good, i.e much more resolving than it was before the ER, among other things... I currently have it connected on both sides with Cable Matters Cat8 RJ45 cables, and wouldn't normally bother with the optical connectivity options, if I did not have an optical module (with Power supply) idling around unused. In spite of my satisfaction with the sound as is, I am of course curious as to whether adding the Opticql module to the chain might bring even more enhancements, as some users seem to have claimed already.-If I am to bother experimenting with the Optical module, though, I would like to get all the connections correct (including the appropriate optical cable length, but hopefully, no attenuators if I can avoid that). One more thing I have idling about is an unused LPS 1.2. I have read a lot about the effects of a Farad LPS, but not enough about the LPS 1.2 on the ER. So far, the stock SMPS is all I have used with the ER, and it seems to be doing fine. If the LPS 1.2 can bring some added improvement, then I wouldn't mind trying it. Any helpful hints or pointers would be welcome. Link to comment

kennyb123 Posted January 20, 2020 Share Posted January 20, 2020 And so begins (continues?) my decent into madness ... Last night I compared two different approaches for applying a total of 20 dB of attenuation. Two pairs of 10 dB on each end vs a single pair of 20 dB on one end. I heard a difference. Then I did some Googling and found this and it gave me a headache. I just ordered a pair of simplex fiber cables so that I can implement the above taking into account the photo that follows from Wikipedia. I don’t think this level of obsessiveness is needed, I’m pursuing this out of curiosity only. I have pairs of 10 dB attenuators on each side right now and it sounds awesome.

I didn’t give it much thought, but I hate the color orange, so I ordered a run of aqua colored single mode fiber. I think things sound great but you have me intrigued. I’ll order the attenuators and give it a try. The other option is to try a better multi mode cable, like the Sonore branded Corning.

Popular Post Jud Posted January 21, 2020 Popular Post Share Posted January 21, 2020 From fiber back to inexpensive copper: 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. 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.

When installing attenuators in a fiber system you normally just install one at the reciever input (Rx) so two attenuators in total on each cable. If you have long cables you normaly measure the loss in the cable to see if the signal that travels through the cable is to strong when it hits the reciever and then apply attenuators so the signal is ok for the reciever. kennyb123 and Jiffi32 1 1 Main system TAD D1000mk2, TAD M2500mk2, TAD CE-1, Ansuz Mainz 8 C2, Ansuz Darkz D-TC, Qobuz Studio -> Roon ROCK on NUC -> Uptone etherREGEN -> dCS Network Bridge -> AES/EBU -> DAC HD Plex 200W PSU (4 rail for ISP fiber, router, etherREGEN and NUC) Second system Qobuz Studio -> Devialet Silver Phantom, Devialet Tree Link to comment

The Monoprice Cat 8 in my system does a very nice job of that. Identical experience here. Started with a Belden Cat6 cable from Blue Jeans with generic plastic plugs from ER to ultraRendu. Not sure if it is the shielded or unshielded version. Tried the Cable Matters for a month, it had slightly better mid bass but I slowly drifted away from the music. I thought the honeymoon period was over and the effect of the ER was fading. Put the generic Cat6 back in, and the magic is back. Did some repeated AB between the two and I would characterise the Cable Matters as rolling off the very top end, compressing and hardening the lower treble. The midrange spatiality which is the major benefit of the ER was lost thing and sound was not pin point precise anymore. The slight mid bass support this sounded blurred and muffled in comparison. The generic CAT 6 seems far more linear, open better highs and better lows and bass was extremely details and very low bass was better. YMMV, different systems etc, but what is better for some can be worse for others. Link to comment
