  1. I currently have a tX-USBexp clocked by the sCLK-EX in my server. Within the next couple days I'll be able to compare it with the JCAT XE.
  2. Yes, I own an SR7 with DR and Paul agreed to build me another custom SR7 which I have not executed for the lone reason that it could be 2 years before I see it and even then I may never. I waited 6 months for mine and I thought that was a long time. I keep an eye on that build calendar thread and it's not positive.
  3. One difference is that SJ's supplies are double regulated. PH's are not unless custom. You can add the LT3045 for extra regulation depending on how you spec'd your supply. The need with an LT3045 is for a supply with slightly higher voltage, but not too high that it creates excessive heat. There is no question that SJ's supplies are quite a bit more than even the custom PH supplies (not PH Design). It has made me think twice and even three times before placing an order, which I have not done yet.
  4. Chris, I hope all is well and you're enjoying beautiful Oregon. Right now I'm using a Poweradd Pro battery to power my router directly. The nice thing about this battery is it has a controlled variable voltage output and based on what I've read at 4.5 amps. Excellent output. Thanks for the response. Do you know how these device stand up in terms of SQ against a LPS-1.2, sPS-500 or even an SR-4? I can do these tests myself in time, but wondering if anyone's done it yet.
  5. I think the architecture goes back and forth and this is impacted by new hardware and software discoveries and experimentation.
  6. For those using the PowerAdd Pro battery, are you needing to unplug the battery from the outlet and use until drained, or can you leave it plugged in without ill effect?
  7. 9v @ 1.5A drives the etherRegen without issue and sounds good. That's good to hear. Looking forward to the higher output 2.1A versions when Alex gets those to market.
  8. HQPlayer doesn't respond well to having dedicated cores? Or it performs better having access to all available cores?
  9. Looking for some guidance on how Audiolinux treats CPU cores for audio applications. When I select "All but the first" exclusively for audio I get one processor available in Roon. If Audiolinux considers Roon an audio application wouldn't it have 3 processors available? My second question is how "Assign isolated core to applications" works with "Isolated CPU cores". I run both Roon Server and HQPlayer Embedded. Is it possible to give Roon 1 core and HQPlayer Embedded 2 of the 3 cores isolated for audio applications, while 1 of the cores is dedicated to the system? What combinations have you tried with core isolation and what are your impressions?
  10. It looks like the Arris AX11000 uses the Broadcom chip so that's positive. Ubiquity is another option but I think they use Qualcomm chips and not sure how good those are. There's also the Asus XT8.
  11. Rajiv, I received an ER and another LPS-1.2 the other day (thanks Alex!). The LPS will likely power the new Arris modem Nennon and Roy were recommending. I have that in house, but am taking one step at a time. I won't go into a lengthy discussion here, but like you I have a TLS and sNH-10G. I didn't wait for burn in. Replacing the sNH-10G I could hear the difference out of the box. I can only hope it gets better. The TLS, which was upstream, will get moved elsewhere in the house and now I need to decide what to do with the sNH-10G. I'm using its taps for my NUC so that creates a dilemma, but I am also looking at a server rebuild and that could make its placement more flexible. I have been testing fiber (with Planettech MGB-TLX Mini GBIC LX Module - 20KM) with both switches. Also moving the placement of the NAS around in the chain, with fiber and without. A side and B side. Comparing direct USB to NAS to Qobuz. A lot of variables and not enough time put into listening yet. Thanks for your review.
  12. Any reason you guys went with single mode fiber instead of multi mode? Are you both still using that gbic linked with good effect? thanks
  13. And here is Emile's comments on HQPlayer with the Extreme... "We have tested HQPlayer version 3.x with the Extreme, DSD upsampling using the most taxing filter back then, polysinc-xtr (non -2s), it can run on 1 CPU up to DSD256, for DSD512 you need both CPUs, at which point it draws about 330 watts from the wall. The EC modulators in HPlayer 4 use even more resources, this is really beyond reasonable assuming using a linear powered server. HQPlayer 4 does do better with higher individual core clock speeds and large caches, the current AMD offerings which we are also testing can do a better job here (at least for value), though not for bit perfect playback as there is some inconsistency between CPUs and even between cores on the same CPU, which we may be able to solve though. The bottom line is we have not given up on HQPlayer."
  14. So the big question is whether the H5 can cool these dual procs successfully and in my case with HQPlayer DSD upsampling. I don't even know whether the SGM Extreme can do this. If the H5 can't then I need to either consider the Xeon build with a fan or a fanless build with a Ryzen proc.
