  1. I agree with the above, I attached a heatsink to mine to prolong its operational life, not because I think you could hear any sound quality differences.
  2. I bought a very similar (but slightly smaller) heatsink on eBay and have installed it today using double-sided heat-conducting tape. I shall keep tabs on the ER case temperature and hope it will keep it somewhat cooler.
  3. Warm-up time for the DAPU is only a few minutes. Settling time from cold to the full effect is less than 24 hours. I guess they are designed that way for fast recovery if a cell tower loses power.
  4. <later> Having done extensive listening, I can say that tweaking the OCXO LPSU to 12.5V has improved performance, so the low dropout regulator is removing more noise from the DC rail. I've settled on the LV-77S clock cables as performing well. The EtherREGEN itself enjoys 12.5V LPSU power and a Black Ravioli grounding box connected to the ground terminal. Both ER and OCXO sit on Black Ravioli Pads. I have ordered a larger heatsink to bond to the top of the ER in order to cool it down some more. A MeiCord ethernet cable from the router feeds into the ER and
  5. I'm running my TP-Link MR6400 router from a Paul Hynes PR3iEHD. Yes, it made a difference over even the Chinese LPSU I was using before.
  6. I'm using Canare LV-77S as my clock cables. I was encouraged (see above) to compare it with its obvious competitor, Belden 4694R. The Canare comes with beautiful Canare true 75 ohm BNC connectors while the Belden comes with black chrome Neutrik connectors. Both are very high performance 4K/8K video cables. I've been swapping back and forth and I'm damned if I can hear much difference, which may simply boil down to style. I wouldn't be able to reliably identify one from the other. Since the LV-77S was noticeably better than the LV-61S, I've probably reached the limiting performance for 30
  7. That does make sense, hearing how much better my 75 ohm version is over my original 50 ohm version. The lightning fast timing and punch are significantly enhanced.
  8. I would almost say it's in reverse with 16/44 benefitting the most. Yes, 24/192 sounds awesome but actually red book material can sound almost as awesome.
  9. I also hear an across-the-board uplift in performance from standard 16/44 material right up to 24/192 on Qobuz. I'm using two reclockers and the rhythmic timing and detail in music is incredible.
  10. Yes, I think it does sound better after several hours of listening. Sibilance is less (as in Paul Simon's voice, which is often mic'd too close) and naturally delivered detail up.
  11. No, of course you're still hearing the benefits of the OCXO. If the regulator is not getting sufficient to cover its dropout voltage, it will simply pass current through without further regulation. I've now trimmed my LPSU to exactly 12.5V. I'm listening and it doesn't sound any worse! I'll let you know long term if I hear any differences.
  12. Actually, looking at the spec sheet, dropout voltage of 340mV means that 12.5V input would suffice to keep it operating.
  13. That's interesting. Seeing as I'm giving it a well regulated 12V already it may pay to take out the regulator and link across, or else set my PSU to 13V.
