  1. Agreed, in the context of 'power conditioner', the models typically have chokes (not the differential type), a set of caps, and a plethora of VDRs. The combo causes unpleasant reaction with linear audio equipment. As far as isolating the 'high' power and 'low' power device, how is it possible, other than to add in another choke. Power conditioners are great for printers and computers to provide for overvoltage protection, but not for audio use. If your isolation transformer is quiet, then yes, it can be applied locally to the equipment. For those of with empty wallets, the Topaz type isolation transformers perform very well for their price, however they aren't spring chickens any more and tend to rattle at low power, and for that reason are best placed at the switchboard. The dedicated line adds more wire were noise is likely not to venture, and the HF currents end up at the transformer anyway, cancelled out when using a symmetrical supply (dependent on the transformer construction and symmetry of the windings).
  2. I agree with format issue, but not the point I made, bit of a sidetrack. HDTracks, just 'passes through' any material from the labels on trust. They were caught out (a few times), a leopard does not change its spots. Providence is rarely proclaimed, another problem with HDTracks as well as streaming services that list a title, but little else. One can go on, but knowing that a mastering is a Dolby A is important, only by diligence in this community would we ever know the whole story. To the formatting issue. One glaring example are the Led Zeppelin remasters supervised by Jimmy Page released 2014. Compressed and bland, the exercise was a waste. The VU meters on my amp were on holiday, not responding to any peaks, if there were any. The Barry Diament masterings were far superior and these are redbook.
  3. 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.
  4. 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
  5. @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
  6. 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!
  7. 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
  8. Thanks and to @mourip, will experiment this weekend.
  9. 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

  11. Another possibility is a small signal transistor on the fritz. As to which one is a methodical process.
  12. 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!
  13. 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).
  14. 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'.
  15. 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.
