  1. What FW version did you upgrade from. I am using 4.22 because it is known to be stable.
  2. I ordered an SR4B-12 on Sept 30th (was lucky to get in the October build queue) and it arrived on November 25th. So I am happy with production time. Wish they had a Fedex option like Farad (3 days) since Royal Mail to Canada is quite slow (2.5weeks). Question for Mark or anyone else. The primary voltages I use for my components are 9V and 12V (5/7/9/12V). This is at the high end of the range of the voltages for the SR4-12. It is at the low end of the range of the voltages for the SR4-19 (9/12/15/19V). Other than the £20 difference in price, is there any rationale for choosing the one unit over the other from a performance perspective. If I order a second unit it might be nice to get an SR4-19, which would give me range of 5V to 19V for future considerations.
  3. Of course the sBooster is not the best available PSU. However with the Lumin connection kit it provides a practical method to directly connect to the DC power input on the Lumin motherboard. No other company provides this type of adapter. Also hundreds of Lumin units have been upgraded with excellent feedback. sBooster provides excellent step by step instructions with photographs explaining how to do the conversion, and they provide the necessary tools including the correct size Torx screwdriver to replace the IEC inlet.
  4. sBooster provides a special Lumin connection kit (compatible with the U1 Mini, D2, and T2) where you need to remove the IEC assembly. https://www.sbooster.com/botw-pp-eco-12-13v/lumin-d2-streamer. There are most likely other mentions of the Lumin connection kit/sBooster in this topic.
  5. I have done an extensive comparison of the U1 mini against the SOtM sMS-200ultra Neo. Disclaimer: YMMV Performance: 1. U1 Mini $US2000 vs sMS-200ultra (with wall wart) $US1200 The U1 Mini is clearly better. Low level detail, musicality, etc. 2. U1 Mini $US2000 vs sMS-200ultra with SOtM sPS-500 external power supply $US1700 The sMS-200ultra pulls slightly ahead. 3. U1 Mini with sBooster external PSU upgrade $US2459 vs sMS-200ultra with SOtM sPS-500 external power supply $US1700 The U1 Mini pulls slightly ahead. 4. U1 Mini with sBooster external PSU upgrade $US2459 vs sMS-200ultra (with SE modifications EVOX capacitor addition and internal OCC silver DC cabling) with SOtM sPS-500 external power supply $US2300 The sMS-200ultra pulls slightly ahead. 5. U1 Mini with sBooster external PSU upgrade $US2459 vs sMS-200ultra (with SE modifications EVOX capacitor addition and internal OCC silver DC cabling) with SOtM sPS-500 external power supply plus SOtM sCLK-OCX10 Reference Master Clock (note1: the sMS-200ultra and sCLK-OCX10 will share the sPS-500 using Y DC cable) (note2: you will need to purchase a 50ohm BNC cable) $US6000+ The sMS-200ultra is clearly better. Low level detail, musicality, etc. 6. U1 Mini with sBooster external PSU upgrade $US2459 vs sMS-200ultra (with SE modifications EVOX capacitor addition and internal OCC silver DC cabling) with SOtM sPS-500 external power supply plus SOtM sCLK-OCX10 Reference Master Clock (note1: the sMS-200ultra and sCLK-OCX10 will each have dedicated sPS-500 units) (note2: you will need to purchase a 50ohm BNC cable) $US6500+ The sMS-200ultra is clearly better. A small improvement versus the previous configuration. Low level detail, musicality, etc. For both the U1 Mini and sMS-200 combinations you can incrementally improve the performance with good AC power cables, good DC cables (for sMS-200), good 50ohm clock cable (for sMS-200) Usability: The U1 Mini is truly plug and play. Setup is a breeze. Once setup it remains stable. The sMS-200ultra is plug and pray. Setup/troubleshooting can become complicated unless you are using the unit in conjunction with Roon ($US500). Roon takes care of sMS-200 configuration and acts as a watchdog to keep it configured correctly. Even with Roon some mysterious issues can occur. The U1 Mini is the clear winner. If you use sMS-200ultra without Roon you will need to exercise your IT networking skills. Features: The sMS-200ultra provides USB output for DAC connection. Note: I use a NOS R2R DAC which only has S/PDIF digital input. To get the very best USB to S/PDIF conversion I use a Berkeley Alpha USB converter, $US2000.00) The U1 Mini provides the following additional features: 1. Additional digital output options AES/EBU, S/PDIF digital (BNC and RCA). 2. Easy to use Apple Airplay and Spotify Connect integration. SOtM offers some integration but be prepared to roll up your sleeves. 3. Ability to handle the first level of MQA decoding, of most importance for the benefit of Tidal streaming. 4. Excellent Remote Control App. I believe that Esoteric uses a variant of the Lumin App. Summary: sMS-200ultra target audience is the AudiophileStyle techno geek who loves to tweak their digital system. The ultimate SOtM spaghetti stack provides excellent performance. If you are not an IT network expert it is strongly recommend that you purchase Roon $US500.00 to simplify your life. To maximize the performance you should use quality aftermarket DC cables and 50ohm BNC cable. Lumin U1 Mini is for the music lover who just wants their system to work. It provides very good performance with the sBooster external power supply. The Lumin App provides good functionality so purchase of Roon is not a must. I own both products (in fully stacked configurations).
  6. I have a weird problem with a Roon / sMS-200ultra/ USBultra setup connecting to the USB input of a Hegel 590 Integrated Amplifier. I am getting a high pitch but faint sound out of my speakers that goes up and down with the volume when either or both of the SOtM units are in the chain. When I go directly from the Roon server to the Hegel there are no problems. In another configuration Roon / sMS-200ultra/ USBultra -> PS Audio DirectStream DAC USB input -> Pass Labs Preamplifier/Amplifier I have absolutely no problems. Trying to figure what incompatibility there is between the Hegel 590 USB input and 200ultra alone or 200ultra+USBultra. I have tried logical checks like swapping USB cables, connecting the Hegel to a different AC outlet, but no luck. Also wondering if there is a Roon Server setting that might solve the high pitch sound issue.
  7. I am stating the obvious, but the U1 is a significant step up in performance over my U1 Mini (with sBooster PSU upgrade).
  8. Peter: Thanks for the answers on the U1 vs X1. In the U1 settings ->Digital Audio Output Setting the S/PDIF, AES/EBU, and Toslink settings can be turned off. If one is using the S/PDIF output and doesn't care about direct connected USB storage device, it would be nice to turn off the USB input/output. --> Is this possible? My guess is no (to support USB storage devices) but it is worth asking.
  9. I am borrowing a friend's U1 Network Transport for comparison with my current U1 Mini. I like the performance improvement of the U1 but the X1 has me salivating, 😋. I read that the new X1 PSU can be used with the S1/A1/T1 using a special adapter cable. Apparently it will also work with the U1. I can see the obvious benefit for the Network Players which have both the transport and DAC (analog and digital sections). Question: How much of a performance improvement will the X1 PSU give to the U1 Network Transport and is this a worthwhile upgrade (versus the Network Players)? What features of the X1 PSU beyond the CNC milled enclosure provide a benefit to the U1? The U1 is based on the transport technology of the S1. Question: What improvements have been made to the transport technology of the X1 versus the S1/U1. There has been much discussion on the improvement on the DAC technology and it is easy to figure this out from the technical specifications and reviews. Which of the following improvements would apply to the transport only functionality (I have crossed out the features that I assume apply to the DAC section only): New processor delivers native DSD512 & PCM768 playback Dual Mono design throughout maximises channel separation Dual ES9038Pro SABRE DACs featuring 140dB dynamic range Femto Clock System with precision FPGA distribution New Output Buffer design Dual Mono dual stage linear regulator Optical Network provides complete isolation from network digital noise USB Digital Audio Output supports Native DSD512 Is there any improvement on the S/PDIF digital output section on the X1 versus the S1/U1? Are there any other improvements to the transport section of the X1 versus the S1/U1 that are worth mentioning?
  10. Definitely not a video issue. Everything outside of the Tidal App has no problems.
  11. I am running Tidal on a Mac Mini, OSX 10.10.5 (Yosemite). When I start up the app, I only get a small portion of the UI displayed, most of the useful regions including navigation just show black. When I move the mouse cursor over some of the regions I temporarily see flashes of HTML content. I downloaded the latest version of Tidal today from tidal.com, and still had the problems. The problem started a week ago, possibly after accepting a Mac OS update that was pushed to my machine.
