Sonore opticalRendu

[Kevin Nguyen]

Cool, thanks for clearing this up. So it is fair and also good to know that US is only a few countries do not charge GST/VAT to buyers. So it is really heaven for consumers. Some countries charge a fortune like 20% off on top of other tax+fee.

I have a switch with existing sfp outputs that are compatible with the opticalrendu. Is it recommended to use the switch’s sfp ports or to preference using the optics’s module with linear psu for the Ethernet to optical conversion instead? i have a concern around adding in the extra box unnecessarily. this is an audio quality not cost question.

 

thanks

In theory, nothing upstream of the fiber cable should influence the SQ of the opticalRendu wrt network noise. As long as you have a good power supply for your opticalRendu there should be no issue using the optical output on your switch.

This goes into some detail on what is happening here.

 

For your specific question, an opticalModule plugged into an RJ-45 jack of the switch is probably going to produce lower phase noise coming out its SFP port than the SFP port of the switch. The result is that using the opticalModule to the opticalRendu is probably going to sound significantly better then the SFP port of the switch going into the opticalRendu.

Not true even in theory imo. That said, it's correct to get the best power supply for the streamer you can. I recently acquired the new Sonore UltraSupply and it made a huge difference. I also go oM to Om before it and that was a huge leap as well, though i don't think the power supplies have as big of an affect on those as the streamer when used in combination. 

 

John's 'fingerprint' explanation is a very good one and what I've thought all along. Garbage in - garbage out (or slightly less garbage out).

Thanks John that is very helpful

Just to confirm, you are recommending a chain of Ethernet -> opticalModule -> opticalRendu?

Yes. This takes care of the clock phase and the galvanic isolation.

Quote of the day

 

"I have received OR+OM. Here is short review)

Before I used my Ultra Rendu with two optical modules and fiber cable (I replaced in modules stabilizers with LT3042). It was great sound (especially with adding optical modules). But OR+OM is absolutely new level! These devices are amazing!!! Unbelievable)."

[geoffc]

What are "stabilizers with LT3042" (youth want to know!)

He modded the generic FMC's regulator:)

Well, I`ve just listened to few albums with my new opticalRendu (with OM) and I`m impressed. Great addition to my Chord M Scaler + TT2 system. Interesting thing that it sounded really harsh at first launch. I left it playing at low volume for 2-3 hours, than returned to it and sound became much much better.

 

All in all - big improvement over my previous streamer (Allo USBridge). I`m constantly getting wow-moments here and there. Better separation, better sense of space, better rhythm, better vocal clarity and absolutely great low-end. I loved my controlled and punchy bass, but addition of opticalRendu made it almost unbelievably good.

 

I`m only worrying about two things now:

1. My opticalRendu runs hot with my 9V PSU. I`ve measured temperature on it`s case - 49 degrees Celsius. It does not get any hotter with time. I assume +49C is ok for it, but at which point should I start to worry?

 

2. Is there any sense in LPSU for optical module? Right now I`m using an iPad charger, which is a good SPSU. Optical connection will not pass any electrical noise, but how about the module itself? Will it benefit from LPSU, or there is nothing to worry about?

 

[barrows]

1. (VDC should be OK for the oR, but watch the heat and ambient room temperature.  The Sonore Power Supply is ideal for it and has 7 VDC output.

 

2.  Yes, the oM will benefit from a really good linear power supply.  The reason for this is that the onboard clock (a Femto level part) will perform its best with perfectly clean DC.  But no need to "worry", enjoy the music for awhile, and upgrade that power supply at your leisure!

Thank you, will keep an eye on it.

 

By the way, does it have a "sleep mode" of some kind? I`ve stopped the music for an hour or so. M Scaler shows that USB input is not receiving anything, but OR it is still consuming 0,8A (according to my PSU indicator) and temperature is almost the same (only 2-3C less).

 

Is it ok to leave opticalRendu on 24/7?

Yes, it is OK and recommended to leave it powered up all the time.  If you are concerned about the heat, I would recommend a 7 VDC supply.  It will also more easily dissipate heat if it is blocked up a bit to allow airflow under the case.

For SFP's to be utilized with System Optique, should they be single mode or multi mode?

Something isn’t right in my 2 channel system. I’ve moved into a new listening room but both my headphone and speaker system are likewise off from where they should be.   The only component change I’ve made is moving from the UltraRendu to OpticalRendu and Opticamodule. My Ultra Spec Cables’ OM1 Fiber Optic SFP cable appears to be much smaller /finer than what I’ve seen in photos of other Optical SFP cables.  To troubleshoot  I need to cross  potential issues off my list such as optical cable problem. So just to hear a alternative cabling I plan to run Ethernet to OpticalRendu. Will be using a high-quality Transparent Audio ethernet cable.  I’ve ordered a SFP to RJ45 to copper module to adapt ethernet to the OR. So my second thought is to also put a Ethernet module in my Optical Module if the OM would still provide a noise buffer between my router and the OR. I I  heresy installing a copper module on the OM or would it still provide some noise isolation?

Optical sounds better than copper Ethernet in every way, so that is decidedly not your problem (and produces better measurements).  If you are in a new room, you need to get to know that room and set up your system for its best performance in that room, start there before looking at any of your components.

Sometimes higher resolution playback gear, just dropped into an existing system context, will not sound "right" until the system is re-tuned to accommodate the higher resolution, so that could be possible as well.  What this is about is that higher resolution playback will resolve fast transients more precisely: in some systems this might sound "bright" as the transient edges are more sharply (accurately) defined.  If this sounds bright to you, it is revealing that your system is bright, and needs to be addressed elsewhere (it did not sound bright before because the lesser resolution gear was rounding the transient edges-less accurate).

These kind of results are not uncommon when increasing the resolution of a given system which is tuned for a pleasing tonal balance the way it was prior; often the system needs to be adjusted, re-tuned, or components now be revealed as a problem might need to be changed.

Will the opticalRendu work well with the Sonore Signature Linear Power Supply?

I would expect them to work perfectly, being from the same manufacturer. I am just waiting to receive and start using mine.

You are probably right. I just wanted to see if the Signature Power Supply has enough current. It was originally designed to power the microRendu.

[barrows]

Yes, the Signature Power Supply (discontinued) and the recently released Sonore Power Supply are both superb at powering the opticalRendu.
