  1. I use WBT silver solder for all my projects. Send me a PM - I will do it for you (free of charge).
  2. Bump. I am surprised this did not pick anyone's interest after all the power supply discussions in the Music Servers forum.
  3. I have 4 rails of the DC3 - level SJ power supply for sale. They have his top of the line components, including the big Mundorf caps Innuos uses in their $14K Statement. Actually, I believe the power supply is identical to the Statement with the exception of the toroidal transformer. I use an oversized 300VA top quality toroidal transformer per SJ’s recommendations. The current configuration is: 5V @5A 3.3V @1.5A 12V @1.5A 5V @1.5A But that can be changed. Since this power supply was in my prototype chassis, that have too many holes, I bought a brand new chassis with heatsinks on both sides. I haven’t mounted the components yet, so it’s easy to customize in terms of configuration, hookup wire, connectors, voltages, number of rails, etc. Send me a PM. As for quality, before I had this power supply, I used a number of Uptone Audio UltraCap lps-1.2 charged by various linear power supplies. I always liked the SJ PS better than the lps-1.2. While the lps-1.2 is an amazing device, I believe the 'energizers' were not up to the level of this SJ power supply (e.g. oversized toroidal, bug Mundorf caps, choke, etc.). The reason I am selling it is because I am moving to another project and have different power requirements. Sean’s price for a pre-built power supply is around $3,000. I will sell for $1,500.
  4. Bob - I hear what you are saying, but with people on different schedules, different timezones, daily jobs, family, different priorities, etc. there is no easy way to do that. We can try to create a local Chicago group, though, and improve coordination and communication between us. And report back our findings here.
  5. And it sounds horrible if you use the software volume control, not just too quiet.
  6. Confirming this works. I tried one of these - https://www.amazon.com/gp/product/B06XSXX3NS/ - on a server that does not support Optane. Euphony recognized the Optane card and I was able to move the installation over. Euphony is up and running from this card. Thanks @romaz
  7. They have removed a bunch of componentes too - the DP to VGA convertor chip, the actual VGA chip, COM port, etc. It makes sense. Those VGA chips are probably generating a lot of EMI.
  8. Let me clarify... I assumed LTG2010 was referring to the green/yellow/red/black cable on the picture he posted that goes from the USB header on the motherboard towards the power supply. If that's the case, I don't think this is a "power connector going direct to the USB/ ethernet outputs". It seems to me like this is a USB cable for the USB LED Controller that can be seen on the picture I posted.
  9. I thought the same at first too. But I believe this is just a USB cable for a USB to LED controller. Zoom in the picture below. There is function to change the front LED light color.
  10. I have a NUC, run Roon Server on it, and stream Roon to one of my streamers. Sometimes. That's not my primary source. The NUC is obviously not connected to my DAC. It's in another room, connected to a tweaked switch, and then I run fiber to my streamer. Did a quick experiment today and connected an Acopian A12MT400 linear power supply to the NUC. I was very surprised from the results in a quite positive way. That's a $300 [email protected] LPS that can be found on eBay for around $100. I have not experimented with any others, but the difference between the stock NUC SMPS and this Acopian LPS was quite significant. To be honest, the result surprised me, because this is an "isolated" (to some degree) server. As I said this is not my primary source, so I did not play too much and did not test any other LPS. My LPS1.2 could not power up the NUC even after disabling everything possible in the BIOS. If you find the Acopian LPS cheap on eBay it might be worth a try.
  11. After listening for a couple of weeks, I can undoubtedly report that I prefer streaming Tidal/Qobuz from Volumio in my system than streaming from a Roon ROCK using RAAT. I don't know exactly why. As much as I like Roon, I switched away from it for critical listening. I still use it for non-critical listening. Roon's soundstage is more compressed in my system. Volumio sounds more alive, more dynamic, more open, etc. I am not trying to start an argument, just sharing my experience.
  12. That might explain the subtle difference I hear when I use Roon. Well, even if that's not the reason for the difference, there definitely is audible difference. UPnP/DLNA software sounds very similar to streaming directly from Volumio running on Allo DigiOne Signature, which does not involve UPnP/DLNA. Roon sounds a little bit different than that. There are things I like about Roon (i.e. bass) and there are things I prefer from Volumio (i.e. wider soundstage and arguably a little more lively). I did go back and forth many times and so far I like Volumio a little bit more to my taste than Roon. We are not talking about a significant difference here... I will probably keep both and use Roon for my day to day listening and discovering new music, because the interface and metadata is so good, and Volumio (with all its bugs and crappy interface, which makes me even wonder sometimes how they can release this to the public!) for critical listening. @vortecjr Thank you for the advice. I am moving away from the ultraRendu, but if I decide to put it back in my system, I will give it a try. I always thought RAAT is more advanced and never even considered trying anything else. Well, I actually tried AirPlay once and was very disappointed.
  13. @arglebargle Right. Roon is not saying that RAAT sounds better. They say a lot of good things about its design but not necessarily that it sounds better or worse. @crenca You are probably right too. I realized what happened. I just discovered that Tidal and Qobuz sound different on different software. I have only compared software when my computer was connected directly to my DAC and I was playing local HiRes files. So now when I use streamers between my server and DAC, my first thought was that it was the streaming protocol. But I am realizing it's the software. And I know, I know, people would not believe me - bias, placebo effect, snake oil, bits are bits, whatever... I trust my ears and know what I am hearing. The software sounds different, and I am not particularly happy with my discovery! Thank you for your responses. You helped me get on the right track.
  14. That makes perfect sense in theory but does not explain what I am hearing. I like Roon, and I bought a lifetime subscription in 2015. I am biased towards Roon and want it to sound better. But that's not what I am hearing. I understand very well how streaming works. And I don't think we would find a logical explanation here. I just wanted to find out if other people have made similar comparisons and what their conclusions were. It may not be that Raat and UPnP sound different. It could be the software. Bits are bits but on a resolving system you can clearly hear differences between different players. Oops, I think I just opened a big can of worms...
  15. That's what I thought too. Not anymore, though...
  16. I have been a Roon / Tidal users since 2015. When I first heard about Qobuz, I managed to get a UK-based free trial account. I used Linn Kazoo at the time to stream to a Sonore UltraRendu using DLNA/Upnp. I really hated the Linn Kazoo software, it was full of bugs, and it felt like going back to the Stone Age compared to Roon. But I remember that I heard a really good sound, which from memory I liked more than Roon / Tidal. I decided to wait until Qobuz comes officially to the States. But the conclusion at the time was that Qobuz sounds better than Tidal. Roon 1.6 come up and Qobuz support was added. At the same time, Qobuz offered me a free test in their beta-closed program in the US. Perfect timing! I was excited to hear the same excellent quality from Qobuz, but it did not sound the same. I started wondering why. Is my memory playing tricks on me, or was it really different?!? In addition the ultraRendu I also have a Allo DigiOne Signature Streamer, which I have been using more recently. I got another SIM card and installed Volumio. It's super easy to switch between DietPi (Roon endpoint) and Volumio by just swapping out the cards and power cycling the streamer. It takes about a minute. So I tried Qobuz there, and I heard very similar sound to what I heard with the Linn Kazzo / DLNA/Upnp the very first time I tried Qobuz. If you go to the Roon forums, they have many articles and explanations how superios RAAT is to DLNA/Upnp. How DLNA/Upnp was put together as bits and pieces and it's afterthought, while RAAT was designed to modern standards, etc. etc. Reading that makes me think Raat is superior. But that's not what my ears hear. Has anyone else compared Raat to DLNA/Upnp? And what is your experience? I am going to do more listening tests, but at this time I am thinking that Raat somehow impacts the sound in a negative way, which looks like more significant difference in sound than the difference between Roon and Qobuz is on most recordings.
