  1. So maybe industrial transceivers have similar benefits to industrial RAM???
  2. Anything not made by @vortecjr can be considered "crappy" in his world. It's funny and ironic how he makes such broad assumptions without any measurements. When in doubt, he also seems to hear a lot less than many others on this forum, which is always a convenient fallback position.
  3. The only way to get a DR SR7 is to have Paul build one, but he is no longer accepting new orders.. You would have to take over an existing order from someone who no longer wants it. The Farad is an excellent power supply but not on the same level as a DR SR7.
  4. This thread has strayed from its intent of providing useful information on the progress and delivery of SR4 and SR7 orders. We are by now all well aware of the historical delays in the custom build queue. As OP, I would like to see no further discussion of past performance since it is not relevant to this topic. Going forward, I will have such posts removed. Hopefully, people realize that a separate business, Paul Hynes Design (PHD), has been created to fulfill orders for standard SR4, SR5, and SR7 power supplies. We are all interested in understanding the performance of PHD, particularly as it relates to their ability to complete SR7 builds. Please feel free to post your experience with PHD as it is also relevant to this topic.
  5. Search the Novel thread. Rajiv compared the Farad3 and SR4 a few months ago.
  6. Each custom build is unique, and therefore, can't be made into a kit. Paul has transferred some of his intellectual property for the SR4, SR5, and SR7 to Paul Hynes Design. These production versions might be viewed as kits, but they are licensed exclusively to Paul Hynes Design. They are not available for DIY purposes.
  7. I have this exact model and cable. The improvements to my system were exactly as advertised. I am thrilled with the performance. I haven't heard this cable, but SR has a new (and slightly less expensive) version with all their latest technology coming to market soon. It will have their silver wire (air strings) and graphene shielding which work so well in my HD grounding, USB, and power cables. There will be a 30-day money-back guarantee, so I plan to try one. If you can find an SR dealer in Asia, you ought to be able to do the same. https://www.synergisticresearch.com/cables/foundation/foundation-headphone/ This is an intriguing product, but more than I would pay for a headphone cable. What most interests me here is the floating ground station. Given the experience with grounding other cables in my system, I would love to ground a headphone cable to my active ground block.
  8. A graphene DC cable would be most interesting. I have graphene in various components and cables in my audio system, and I believe there is something to it.
  9. Yes, two pieces of equipment can be plugged into a dual rail supply. Paul once wrote me the following in regard to a dual rail supply: "There is a slight sonic penalty with having all the transformer secondaries on one transformer core as nothing is absolutely perfect and there will be some small level of interaction due to transient load current swings. This may be audible in a high-resolution system but it would be rather subtle due to the very high supply line rejection of the voltage regulator circuitry in the DR mode." The SR5 that you are contemplating will not have DR (double regulated) circuitry as it is not part of the standard SR5 offering. You will have single regulated (SR) circuitry instead. Nevertheless, in practical terms, any interaction would probably be so minimal that you would normally not be aware of it.
  10. The primary benefit of dual rails is the lower cost per rail. There are also efficiencies from having two rails located in the same case. For example, only one power cord is needed, and less space is required on your shelf. Theoretically, there could be some interaction between the two rails that could slightly diminish sound quality.
  11. Thanks to you and @paulhynes for taking the time to pull all of this information together.
  12. This is exactly what I hear, too. As the first NUC user to recommend the Apacer memory, I didn't want to risk overstating the change and have others be disappointed. Hence, my description was more conservative. Yours is more accurate.
  13. That's an interesting way of framing the question. For now, I'll defer to @elan120 for his perspective since he has done more tweaking with AL and his NUC than I. I haven't tried one SIMM yet, but it's on my to do list.
  14. @Mark (Paul Hynes Design LTD) is not affiliated with Paul Hynes, the man, and builder of custom SR7s. He is an employee of Paul Hynes Design LTD, which is a distinct company which presumably has licensed the right to build certain power supplies originally designed by Paul Hynes. Although I wish it were otherwise, I believe Mark has limited ability to coax Paul Hynes into being more forthcoming about his custom SR7 business. Beleaguered SR7 customers have repeatedly beseeched @paulhynes for more transparency, but for some reason, he appears to believe the best business strategy is to remain unaccountable. An occasional post to this thread does not necessarily have to be a time consuming expository essay that would detract from his limited bench time.
  15. Unfortunately, I’m not set up to make such a comparison. Since all of my PSUs are either 19v or 12v, I have no equivalent to the 16v PP2 for use on my HMS, which requires a 15v or 16v power supply for optimal sound quality. I know from past experience that a certain coveted DR 12v rail had minimal benefit relative to the stock 15v SMPS, while the 16v PP2 + 16AWG Neotech UPOCC 7N copper DC cable makes a more obvious improvement. While some might question my finding that the 12v DR rail has a negligible effect on the HMS, I do not believe their HMS as well as both digital interconnects are grounded directly to an active ground block as are mine. In my experience, this type of grounding lowers the noise floor, which in this particular use case is possibly negating most of the benefits of the “quiet” DR rail running at less-than-optimal voltage.
  16. I'm unaware of anyone who has heard a Farad Super12, much less compared one to an SR7. What is basis for your comment? Thanks.
  17. I have used Beeswax fuses in linear power supplies and don't consider them to be overly warm. Mostly, I find them smoother and more liquid sounding than SR blue fuses, which have more energy and greater transparency in comparison. I mostly prefer the Beeswax fuses in those power supplies, but my choice also depends on the component being powered. You might consider trying a blue fuse with your SR4. If you like it, then don't worry about the Beewax. SR offers a 30-day money back guarantee that removes all of the financial risk except for shipping. I would guess they have a dealer somewhere in the UK. The rule of thumb for the blue fuses is to order 1.35-1.6x the rated amount for your device. I do the same with Beeswax fuses in order to avoid a blown fuse. I haven't had any issues using the higher rated fuses.
  18. The SQ of both the switch and master clock can be significantly improved by better power sources. Skip the SPS-500 altogether (it's not very good) and look for something like a Farad3 or SR4. Get a good silver DC lead made from Neotech 16AWG solid core silver wire for the Farad3 or the Paul Hynes silver lead which can be ordered with the SR4
