  1. I'm going to respectively disagree here. The Etheregen doesn't care, the clock may not either since it has very stable supply inside. The issue is how will that supply affect the rest of the system as far as conducted emissions (noise) is concerned. More power supplies create more noise, it's fact. The less of them the better.
  2. At the music server side. Switch -> Baaske -> [Music Server jcat nic 1, nic 2] -> ER A side. If you have two more, outgoing of switch to music server, the other in the drawer as spare.
  3. The setting on your x to flac converter slider needs the compression level set to 0, good to go then.
  4. The harmony fuse would have to be the ugliest fuse on the planet. Synergistic at least make a good looking product in comparison, so is perfectly flawed. That coating on the fuse looks like painted on cow poo, must be that CEF treatment . The etching on the fuse rating is very much an industry standard, and no distinction between fast or slow either. Just a standard fuse. To provide that level of attenuation that fuse would get so hot, the holder will melt. The shoe insert was mildly entertaining placing a conductive material on an insulator, the sock and shoe,
  5. I must admit to hearing sibilant from Diana Kraal recordings. Since the Baaske isolator, Jcat net femto and bonding chassis and drives together I don't hear many cases , cause I normally stop listening and try something else. Lumin U1 for nearly two years now.
  6. Depends where the existing one is, how the network is structured and where the files are stored. A little drawing or a workflow would help heaps. 😀
  7. Re question 3. Ok on a mapped drive where the music is stored. If a new album is saved, how long does it show in the list to play? Also does clearsound receive upnp?
  8. Thank you for the focus! Questions - Take it playback is at the file sample rate - what's the maximum DSD rate? - plays over network? - prices? - different versions for WASAPI, Asio, fair enough, what's the OS support? I'd guess no Linux or MacOs, which versions for Windows? - any library size limitation? Interested!
  9. Thanks for the tip! So far the Lumin always connects with the ER, maybe an update fixed the Windows swapping the MAC address. If it plays up, will follow your tip.
  10. Yes, this is normal practice now, even before the EtherRegen was installed. All devices are DHCP with the router assigning fixed IP addresses according to MAC Address. The one exception is the SACD ripper BD, where the address is assigned locally. The reason for using bridging is here,, related to the first post: A novel way to massively improve the SQ of computer audio streaming. Bridging avoids the connection to another switch (this eliminating the crap that's picked up along the way there), and maintains the integrity of the JCAT Net Femto card.
  11. Just weird unexpected behaviour, send me nuts. Like for the jcat net Femto card essentially uses two nics, each one has its own MAC. Wired : Router > Nic 1, Nic 2 > ER > Lumin I’ve bridged the Nic 1 & Nic 2 connection in Windows and the router assigns the IP address to the ‘bridged’ Nic MAC address which is usually Nic 1. Nic 2 is not assigned and the Lumin is setup for DHCP, so it works. Now for some reason, on a reboot, Windows assigns the other nic’s MAC and the Lumin doesn’t connect cause it’s not getting the IP address although it remains co
  12. The speaker output is way too powerful to use and will overload the bluetooth transmitter. It's only good for 'line level' signals. If the amp has a REC out, use that instead with the appropriate adapters. Or something like the Erskine Unit.
  13. I wonder if the router is refreshing the lease, some do after 24 hours. Some routers allow a refresh time of 999 hours, others don't have a setting at all. If the latter, perhaps assign the Aurender MAC address a permanent IP address, in that way when the refresh occurs, the assignment works right away.
  14. It hurts when a fellow member suddenly disappears, all we have are the words to remember now. Condolences for his family on the loss we all share. Sadly will be missed.
  15. Well, this morning, the EtherRegen was powered down all night. Left the power on 30-45 minutes before listening, seems to have stabilised during this time, it's about the same time for other electronics to settle down. I would say all attributes have returned since yesterday. Will work on a changeover system when the main system is off the EtherRegen stays on from another PSU and switches to the linear supply when listening. Would be nice to have some data go through, but that's really messy.
  16. The BNC connectors are not connected to the chassis or thumbscrew of the EtherRegen, so they float. So if the splitter is floating you won't compromise the moat. Perhaps long term to consider the Mutec REF 10 or MC3+USB for clock source?
  17. EtherRegen listening evaluations day 10 (252 hours burn in) Last post saw elevated voltages on the normally grounded connectors with the ER in place at 6 Days burn in. Today, finally, the voltages are under control, there's maybe 1mV DC offset between the 9V on the PSU and any point that references to 0V, XLR sheels, USB shells, Lumin ground point. The BNC connector floats above ground, which it should for clocking in case anyone has an interest there. How does it sound? Like it's supposed to, wide sound-stage, instruments spread out with no holes in the image, just a s
  18. Common mode noise is a conducted rubbish unwanted signal that is created from any semiconductor switching device that with its own capacitance or bolted to a metal surface forms a circuit to its 0V. It's that (very small) voltage that can transmit over signal wires that is troublesome for devices like DACs and clocks therein. From my own observations, common mode noise reduces sound stage height and depth, creates a point type source image, very much like a mono presentation. Common mode noise interferes with resolution of very fine instruments like cymbals, snare, and muffles frequ
  19. Not so much sure protection, cause the switch or router upstream is usually charcoaled. The main benefit of the LAN isolator is to break the common mode loop and that it does quite well.
  20. Of any use, a repeat post the other day on power supplies: The EtherRegen doesn't care what feeds it, really. What matters is what the power supply does to the rest of the system is where the differences are heard. This is based on listening using two PSU a linear supply AC fed from audio balanced supply, and the Uptone SMPS on an IT only 120V AC. Different devices, with very little difference with the audio. Depending on the power supply, it produces switching noises which couple to earth and feedback through the AC network, and to DACs or amplifiers for that matter, w
  21. The EtherRegen doesn't care what feeds it, really. What matters is what the power supply does to the rest of the system is where the differences are heard. Depending on the power supply, it produces switching noises which couple to earth and feedback through the AC network, and to DACs or amplifiers for that matter, where it the effects are audible. Switching may be regulators or bonded rectifier diodes or FETs, or an ICs that are capacitively coupled to the chassis of the power supply. It's how the PSU filters these artefacts will determine how it sounds. Generally loo
  22. The problem of adding the voltages are not due to the power supply, since the adding of Volts is via the signal leads. So even if the ER was supplied by a separate power supply, the higher voltage on the XLR shell would still be there. I should have measured the AC component on the DC rail, in retrospect to find out where that signature came from. In any case removing the ER collapsed the added voltage. I see where you’re coming from in that having the two devices on the same supply in parallel causes the added voltage as they interact? That would be true if the power
  23. That looks OK! A lot of us have a type of Panamax, Furman, Monster Centre that really does squat for audio protection. The coils they use, for some reason, react with rapid current from amps especially, and the abundance of caps just seem to resonate at the wrong frequency with clear audible detriments. However, they are a real plus for computing equipment, fridges, your sump pump, printers, anything other than audio equipment and TV. Line conditioners usually have very good protection circuitry like overvoltage and undervoltage sensing or lost neutral detection that really works well. A
  24. The RF versions of the ISOMAX are awesome, for the likes of Cable TV/FM systems. For audio. There's only one shop, at Lundahl transformers. Functionally, they do the same job as the ISOMAX, but, the price can be eye watering versus the quality, Some Lundahl transformers are thousands, choices.
