With all of that extra clarity, it did seem to lose some mids weight and musicality (toe tapping) but I'm thinking that's mostly a case, like I said, of getting used to all of the new detail. 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.

@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? (I'm not sure if one side of the fiber cable sends one way and the other the other way?)

What about trying less attenuation?

 

Yeah, probably need to buy a mix of these and experiment.

I believe one leg sends and the other receives.  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.

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!

Would someone please post a photo of exactly where and how these attenuators go?  
 

In case it matters, I’m running copper Ethernet out from a switch into an Optical Module, then fiber from the OM out to the EtherRegen then copper Ethernet out from the EtherRegen into the dac. 
 

I bought two pairs of 10db and 7db attenuators.

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.

What type of SFP modules do you use?

 

I use LX modules that have a range up to 10km with single-mode fiber and I asked FS.com if there were any risk of using them with a short fibercable but that was no problem with the model I bought.

I’ve been using pairs at each end.  Simply remove the cable from SFP, insert the pair of attenuators, then insert the cable.

Octaviars, I use the pictured TP-Link one in the EtherRegen and Sig rendu and Ubiquiti-branded compatibles between the TP-Link FMC and opticalModule. I use LC to LC multimode cables.

In my case the over-saturation was causing treble to get too hot on songs that already had that tendency.

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.

Your biggest risk comes when using Single Mode ER (40 Km) and ZX (80 Km) optics, which can overdrive and even burn inputs without sufficient attenuation.

 

There is no risk of burning Multi Mode optics like the ones you use with short cables.

 

Thanks very nuch.

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.

image.png.aaf3dc93951723d9a7a946456e8c31df.png

 

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.

Let me reiterate that my system has never sounded better since implementing this fiber solution along with a pair of 10 dB attenuators on both sides.  For most of you using single mode fiber, I’d suggest ordering two pairs of 10 dB attenuators from Amazon.  Try them at both ends.

I was hoping to sell my LPS 1.2 after installing the EtherRegen, but some A/B comparisons with the supplied SMPS made it clear that it was worthwhile using LPS 1.2 the feed the ER.

I happen to have single mode fiber. 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. But if I post a question on sound quality of optical cable I’m sure to incur much derision on this forum.

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.


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.

12 volts. I think Alex recommend that when using the 1.2.
