  1. That’s a workable response and can manage the two of extremes and a rise of 25-30C on the safe side. It’s trivial for me to control the temperature , the temperature ranges 5C - 40C at the extremes and the EtherRegen would only be active when the audio system is on and usually not above 32C. Didn’t plan on a cupboard, there’s room behind the Lumin which is open air, a few weeks of measuring and the optimum air flow should keep that temperature stable. Thanks for the great response!
  2. @JohnSwenson, reading the post about the EtherRegen’s temperature of a nominal 50C as a ‘sweet spot’ for CMOS stability, is the ambient reference 25C? Thing is if the ambient is hot like 35C will the temperature increase beyond the 50C? My question is to ask whether there is a need to force cool, arrange free air around the case or perhaps there’s a Temperature regulator looking after this.
  3. Isn't I2S limited only by a few cm? Or is that something that Gordon Rankin said. I2S over LVDS is certainly possible if there's a length of wire on it, or has I2S morphed into an LVDS transmission these last few years?
  4. My original post was badly worded. Too late to edit. Wikipedia explains better: Limitations The receiver does not control the data rate, so it must avoid bit slip by synchronizing its reception with the source clock. Many S/PDIF implementations cannot fully decouple the final signal from influence of the source or the interconnect. Specifically the process of clock recovery used to synchronize reception may produce jitter.[9][10][11] If the DAC does not have a stable clock reference then noise will be introduced into the resulting analog signal. However, receivers can
  5. AES, SPDIF are missing clock signal data, well, the receivers screw up the clock data, so a new clock needs to consitute that data. AES can run for a 100m, SPDIF for 5m. USB conducts noise from the source to host. SB is maxed at 2m without tricks. HDMI has a shitty connector, can have clock data, but no one has set a standard. Fibre can contain clock data, can run for thousands of metres, and pumps 10GB+/s. Seems ideal. Ethernet has Ravenna, that's taken off like a lead balloon, for consumer, pretty much a closed shop, Dante still has a commandi
  6. Look for the highest damping factor, as this controls the amount of excursion on the speaker. Have a good look at some restored Marantz or Citation amps 1970's vintage. Sansui is another but I read reliability is not as solid as the Marantz at this stage of life.
  7. The Roman type font for the album title and regular looking font for tracks still looks odd as the change requires rereading to confirm what the album is. The one font is preferred to stop the back and forth. Sorry in advance of the font styles naming, not a professional.
  8. Is the roon core on Euphony OS or another OS? Not the server version, no?
  9. VPN will be busy overcoming the ‘select market’. That phrase is hated by those that are the ‘unselected’. Doesn’t mention above redbook specifically, but doesn’t matter most commercial rock pop hi res sounds like redbook anyway.
  10. Conversation is now a parallel. No further dialog necessary, bye.
  11. Oh! You’ve never held a scope to a signal and the problem went away or was worse? This is lead loading, never experienced this ever.... ? then I take it your expertise is software and theorist electrical, that’s ok. if you have a closet full of USB cables and can’t hear a difference with any of them, then your perception is different to the most of us here.
  12. Ok, any high impedance probe on a scope has far too low an impedance to measure this conducted noise. It is necessary to have several gigs of impedance, so the scope will have no influence. 18th century telescope is what we have now. It easier to measure noise at frequencies above 30 MHz, since the receiver is decoupled from the source. Soon as there are conducted emissions through a wire, the story radically changes.
  13. Since you are not electrically minded, think of the noise that is on top of the USB signal as a virus. Currently the tools we have to measure that virus is a 18th century telescope. We know it’s there, can hear the effects, make a good guess of what it is, but cannot measure. Thats why there is very little data since it is difficult to measure in the first place. When I mean difficult the instruments are well beyond most professionals starting at EUR150k +++ and that won’t get anywhere close.
  14. Tash Sultana - Terra Firma (2021) [Hi-Res] There's something maturing here with Tash Sultana, willing to add splashes of brass and extra colours to these unique songs. Almost Chillout at times, great guitar work, thank you! SQ wise, great separation of instruments, superb imaging, recorded at 48/24, I find the 48's well recorded, leaving the 96 in the dust, and not necessary.
