  1. Thanks... Is this type better than similar models from Furman on Panamax?
  2. Agreed... I wish I could start some kind of glossary of related technical terms. That would certainly help, as a start.
  3. @barrows, @Puma Cat Thanks for your informative responses... I do not have any immediate remaining questions to ask, but the topic of these power conditioners interests me, so I have created a forum for it on this site, just in case other questions come up, or in case other posters have some related input. Here it is:
  4. This subject started as a general effort to understand the uses and benefits of power conditioners, power distributors, and surge protectors, within the context of noise isolation technology in network audio, notably in the digital domain. I was specifically interested in learning how to balance the use of such power conditioners with the linear power supply units that one normally uses to power individual components, such as network players, Dacs, Amps, (but also Routers, modems, Switches, and FMC devices, etc etc) in order to isolate noise and optimize sound quality. However, my interest does not necessarily end there. I am interested in learning about the function of power conditioners and distributors, and everything they can do, not only to protect equipment, but also to improve the quality of the A/V signals such equipment produce. I am aware, in a general way, that power conditioners are meant to provide clean power and protection for our equipment under a variety of conditions. The protection they offer from power surges, and variations in voltage, as well as the work they do in filtering out noise, and preventing components from sending such noise to others within their orbits of operation and influence, are all very vital in helping us to get great performance from our rigs. However, I also understand that this is just the basic surface-scratching stuff, and that a lot of in-depth discussions, elaborations, specifications, are still required to deepen my knowledge of these types of equipment, and the processes involved in power conditioning and distribution themselves. I also understand that there might be various differentiations, discriminations between units, brands, models, and functions that remain to be made, as the science behind much of this stuff remains rather murky to me. I am here to learn from the experiences of others. What exactly constitutes this "clean power" that we crave for our equipment? What are the components that are apt to produce it for the best performance of our equipment, and at what cost? Are some of the units more efficient than others in functionality and durability, and for which specific contexts and applications? Which ones should one avoid, and what are the best practices in ensuring the best performance of the ones one chooses? I am sure there are even more pertinent questions out there that remain to be asked, and related issues that remain to be raised, interrogated, and properly sorted out. I am keeping this as open as possible, to all pertinent forms of input. Commentaries, discussions, elaborations, impressions, critiques, etc. etc,-- are all are welcome, as long as they're related to the topic at hand... So please sound off:
  5. @barrows, @Puma Cat : Not to beat a proverbial "dead horse," but where do power conditioners/surge protectors with multiple outlets like those from Furman or Belkin fit into these optical noise isolation configurations, if there are any places for them to start with? I wish I did not have to ask, but such "conditioners" have always been part of my rigs, not simply for surge protection purposes, but also for their much touted "noise filtration" technologies, which often do a great job in removing all kinds of line noises and hums from my rigs. Heck, I am just about to replace the standard power strip I use for my main modem, router, Synology NAS, and an attached external hard drive, with a Furman power conditioner which has 9 outlets. This is going to be a sort of set and forget it solution, and yet, after reading your recent comments, I am no longer sure that I am applying the ideal solution in this particular case. However, for reasons of sheer logistical convenience, I cannot approach this following a one-LPS-to-one-component method, which is what makes such 9-outlet power conditioners and others like it interesting to me... You see why I cannot stop beating this dead horse? It is really not dead for me, to begin with. At least not yet 😉 Which is why I am curious about methods you use to manage noise in your own audio environments. 😉
  6. @barrows, That is extremely well explained, and very helpful. I do have some clarity about these LPS options now. Thanks.
  7. Yes of course, that is also possible, except that I only learnt about it this morning by reading one of the posts of Barrows or Jesus. Until I did, I was inadvertently assuming that long runs of fiber cable were not advisable (perhaps because they uniformly recommend customized 1.0m versions for the fiber cabe for the OpticalRendu and the optical Module)... I am happy to learn that I can use longer runs.
  8. The point is well taken, but then it immediately brings to mind the 200w LPS pictured here, which I have had on my SGC wishlist for a while now, precisely because of the claim that it is "Great for powering the ultraRendu or microRendu, ultraDigital, and a sonicTransporter at the same time." I am assuming your statement might be restricted to powering the "opticalModule and the opticalRendu" with the same LPS, however, my perfectly non-expert point of view is tempted to extend that meaning to practically all Sonore products (and others) that might require a power supply, and if that happens, I'd just have to strike that 200w LPS of my wishlist, as I would like to avoid the possibility of reciprocal noise pollution of any two or more components being powered simultaneously by that 200w LPS To simplify my question : which sonore components, if any, could use that LPS jointly without running the kind of reciprocal noise pollution you're warning against? Could i use to power both an OpticalRendu, and a Sonic Transporter, for example, without exposing both of them to mutual noise infection? I am also tempted to ask how it stacks up against the upcoming UltraSupply, when paired with the OpticalRendu and another unit (where the reciprocal noise pollution is not an issue). Can one use the 200w LPS to power the OpticalRendu and other components simultaneously and still get performance that is comparable to that of the UltraSupply with the OpticalRendu?
  9. Oh, I wanted to know how your Ghent Audio ethernet cable (JSSG Cat 6a) stacks up against generic ones, in your view, that is, if you in fact see any noticeable differences in performance?
  10. +1... I'd be interested in knowing the outcomes of these experiments too.
  11. Thanks for the link. I'll trying replacing the RJ45 cable between the opticalmodule and ultrarendu with one of these furutech cables, just to see what the results are. Still, I am wondering how important I should consider the RJ45 cable between the Router and the Opticalmodule and the first FMC module (if there are two of them in the chain) in defining the sound quality in such a chain...? Any ideas about that? I notice, for example, that you have 2 of these furutech cables in your chain, one deployed between the router and Trendnet/SFP transceiver and the other between the optical module and the ultrarendu. Do you think the ethernet cable coming before the Trendnet/SFP transceiver is as important in defining the final sonic outcome of your chain, as the 2nd cable that is connected to the Ultrarendu? I am asking because I would like to avoid replacing the cable connecting my router to the first FMC transceiver in my chain if possible (it is too long as it stands now, given the requirements of the layout of my equipment in my room, and will therefore be quite expensive to replace. The distance between my opticalmodule and my rendu is extremely short, and very manageable, in comparison)
  12. What furutech ethernet cable are you using? Could you kindly provide a link to it, if possible? Thanks.
  13. So I have got the Jameco power supply installed, and those dropouts are gone. To be fair, I have also updated the OS on my mac mini/Roon core, and that has eliminated incidents of slow timing responses on Roon, that was causing some of the previous irregularities. Thanks for suggesting these power supplies.
  14. So is the deafening silence I am detecting here the sound of all the opticalRendus out there burning in, or their enjoyment? I am just hunting for owner's impressions, so if any owners care to chime in at this time, their contributions would be welcome.
