  1. I haven't purchased HDTracks for a few years now, the numbers did not match the hype. Their were only a few gems, the rest was not much better than CD, they don't QA. Egad, the cost! HiresAudio on the other hand, test each release to make sure what is delivered matches to the sample rate, and not some upsampled nonsense dished out from the labels.
  2. The phase to inversion was me, it was a few days in between checking, and I normally don’t save any changes, maybe SF14 does. When I’m back home can redo. the channel swap is the web rip. found another will transmit
  3. @wklie, for the Lumin U1, I tried to play DSD256 file via Roon, and there's silence. DSD128 and below works fine. In the Custom sample rate on the Lumin app, the max rate is DSD128. Switched off all custom rates and still silence. Config Lumin U1 USB #1 and USB #2 -> Acoustic Revive split USB power and signal cable -> USB 'B" input Accuphase DP-950 DAC
  4. I couldn't Ethernet bridge the internal NIC to the Femto, initially it would accept (Ethernet to Ethernet 4), then on a reboot, the existing Bridge on the Femto was maintained, (Ethernet 3-4). The PC had net access which is fine, but the Lumin was showing a disconnected mode, easy to spot "Network error". The connections now are: Router -> Switch -> Baaske filter -> JCAT port A (Ethernet 3) [Bridged] -> JCAT Port B (Ethernet4) -> Lumin U1 I need network access to monitor the server and to add/subtract new music files. When playing music, "Atomic Blonde" OST Redbook, the two internal NICS (Ethernet and Ethernet 2) were disabled on the fly, and wow, the bass improved, deeper, very nice tip there thank you!
  5. One of the many reasons not listening to Tidal was that the music sounded different compared to the Cd rip and played locally. I came across a Web rip of a very familiar album that I've owned since 1987, it's Thom Rotella Band self titled CD on DMP. DMP were pioneers of digital recordings back in the day, the Roon DR range on this particular album is 18. Tracks feature percussion with all kinds of hidden triangles, shakers, and the drum kicks are as about 'real' as there is. The album comes out when there's a new piece of equipment, or experimenting with interconnects to reset the reference and to find any new gems. The Web Rip when listened to on speakers, strange, something was missing and something added. The attack of the drums is missing, and sounds mush. The analyze audio from Jriver was not that conclusive, since the playback volumes were different. Opened sound forge and measured the frequency analysis, without tinkering with too many settings. Well, there's some differences. Web Rip, Patti Cake 30s sample CD Rip Patti Cake 30s sample On the web rip is DC? Going years back now, Audacity had a habit of creating oddities, was this one of them? Being that as it may, the upper ranges below 22kHz are very different, with 19k has little worth. Either the source or audacity (?) aren't working to the full fidelity, vindicating my view streaming media is great for cars, background listening and exploring new music but for critical listening, not to be taken seriously. 01 Patti Cake CD Rip 30s.wav 01 Patti Cake Web Rip 30s.wav
  6. Thanks and to @mourip, will experiment this weekend.
  7. If I could ask @Marcin_gps on an application re-config. I don't stream Tidal/Qobuz. Music files are stored on Win2016 single Xeon music server, Roon core. End Point is Ethernet Lumin UI. Lumin requires active access to the rest of the network, has DHCP, but would the PCIe serve as a bridge? Win2016 has routing capability, wonder if this could be put to use. Bit of a learning curve, rather keep the network on one side and the JCAT Net Femto on the other. Chain at the moment Router -> Switch -> JCAT port A [Bridged] -> JCAT Port B -> Baaske filter -> Lumin U1 Propose (will it work?) Router -> Switch -> Baaske filter -> Music Server Internal NIC JCAT Port B -> Lumin U1

  9. Another possibility is a small signal transistor on the fritz. As to which one is a methodical process.
  10. Nice one, keep it. I have returned to vinyl after 40 + years without. It's a welcome change to see something moving other than pixels. You're not alone! HQpPlayer is the king of upsampling, various methods depended on what type of material was being played. It was all too much of a bother, and hassle. Music played at the format's sample rate is pretty darn good, been like that for years now . 😄 Enjoy the X1!
  11. Dedicated line from the main panel to the audio system trumps a line conditioner plugged into a standard wired wall socket every day. Some iso transformers are noisy, when lightly loaded, and are best placed at the switchboard. Shielded cable from the Transformer is recommended, since the cable run can be some distance, and can pick up noise from other cables in close proximity. The worst kind of pickup is from a large circuit, like A/C or deteriorating light switches which don't switch clean, and create a click which is audible. Safe distance is 200mm (8 in).
  12. I would agree. @sbenyo , Take a note of the times when the music turns sour., random or during the day? There's elements in the power conditioner that react with audio components and the line to create some very woolly effects, the swiss cheese effect and could do more harm than good. The Accuphase devices have very little in the way of noise generating DSP actions and are classic amps that don't do that. Next step is to clean interconnects and connectors on the pre and power amp, and internal switches with Deoxit. It's unlikely the switches are wearing out, but are susceptible to dust entry, and that could also cause SQ problems from one moment to the next. My E-205 needs attention to the selector switch fairly regularly, the sound drops off or just sounds 'off'.
  13. I need to disagree here. unbalanced promotes common mode noise and bonds grounds from one component to the other, which leads to ground loops formed through earthing conductors on the AC side. Balanced is inherently common mode noise rejection, with bonding of the chassis of equipment in a separate conductor and not bonded to the ground point in either device, unless some twisted designer had done so. unbalanced works in phono cartridges since there’s no loop to create, it should never have been used for line level sources with earthed chassis equipment.
  14. Finally had some time to iinstall and then compare the Lumin app. Lumin recommends Minimserver, so, OK. There's a bit of effort in installing minimserver and to make it work. As an advice from Mininserver pages: "If your music files are on another computer, you should install MinimServer on the other computer, which will need to be running whenever you're browsing your music collection or playing music. You can install MinimWatch on a Windows PC if you want to use the Windows PC to configure and manage MinimServer. You don't need to be running MinimWatch to browse your music collection or play music." Well, the music files are on a different computer to where the Lumin is connected. The advice is then to install Mininserver on the machine where the files live, but it's a noisy Server, not adapted for audio, just general use and I would have to move the JCAT net card. Despite this advice, Minimserver picked up the files on the other computer, it hated the UNC convention \\Main-Server, but approved the mapped drive T:\. 🙄 Firewall Mininserver install doesn't poke a hole in the Windows 2016 firewall to let through traffic to the Lumin app on the ipad. For linux, UDP port 1900 needs to be open, made rules for both directions, didn't work. Switched off the firewall and the server could be seen by the Lumin app. Mamma mia, what a process. I could find the ports to open in Roon took a little time, but for Minimserver, it's a STRUGGLE. Java If an application needs a port open, it's fine to configure in the windows firewall, but windows chooses the exe file, minimserver runs on java, so the whole of Java needs a port open? I don't know, but that's an open door to something I'm not too keen on. Scanning music files Oh Minimserver hates the %date% format on every .DSF, can't understand 11/12 Update If new music files are added to the library, these need to be re-scanned manually, can be done on the fly, the server does stop and start. I suppose for an album it;s tolerable, but a box set may see an interruption. Roon has its days, sometimes indexing works right away, other times, it takes its sweet time. If the PC reboots, it will re-scan all the folders. It's quick, but not immediate, Roon is just a few seconds, on the iPad about 10s something to wake up. After all that endurance above, comparison of the SQ of Roon and the Lumin app - Stage height: same - Stage Depth : same - Micro details like snare drum/ brushes : Lumin app gain, to make it a measurement, 3 grains of sand - Bass : same - Vocals : No real difference Interesting excercise, if there was a choice, I would go Roon not due to SQ, just for ease of use and familiarity. Lumin app does work in portrait mode on my iPad which is really cool, for Roon, landscape only unless I buy a new iPad (Pro). Have better things to spend on than line Apple's pockets with cash.
  15. Being involved with Power Inverters/UPS, one UPS manufacturer from Japan during the 80's went through a new brochure with us, so we could add our distributor details at the printers. There were two scope photos, one of the beautiful sine wave output, the other 'without' the UPS was a mass of crud and rubbish. It was revealed by the manufacturer, that the 'without' photo was taken from the input to the UPS at rated load and not really indicative of real without the UPS situation. Another irk is the standard for testing EMC filters, the network chosen to measure from is unrealistic. So measurements in isolation, never relate to the real world, in an audio case where chains and multiple paths have effects that are not considered in equipment on their own. The rare exception is the EtherRegen with its ground binding post. For once, Uptone has thought about the rest of the system. Whether to use it or not is up to the owner, heck I would, and run it back to the ISOTransformer ground point.
