  1. Interesting. I wonder if he found a difference or tried all copper Ethernet. It's difficult for me to justify how the optical wavelength used could impact the sound and flatten or crush the sound stage; perhaps unless the 850nm SFP were faulty but again, it's a situation of either signal or no signal. It can be too low or too hot but this will only cause retries or dropouts of the data. It's cheap to experiment but use caution to not to lose the forest for the trees (or music). fyi and fwiw, I have an ER in my system and very much like what it's brought to the system. I've got copper from a Cisco 2960G feeding it and 850nm multi-mode out to my server with PCIe board then I2S to my DAC.
  2. There should be no need for attenuators unless you're running LR - Long Range transceivers, in which case don't do this, as they are designed to shoot many kilometers. SX - mulitmode and LX - singlemode should work just fine with a 1M fiber patch. The lasers won't over drive the receiver. If the receiver is being over driven, you likely won't get link/signal and if you do it will drop and recover over and over until the receiver is burned out.
  3. Yes, CAT 7 and 8 are both shielded (STP) designs and require the metal shielded connectors, as does 6A STP (as opposed to 6A UTP). There are other variants of shielding: Individual shield (U/FTP) Individual shielding with aluminum foil for each twisted pair or quad. Common names: pair in metal foil, shielded twisted pair, screened twisted pair. This type of shielding protects cable from external EMI entering or exiting the cable and also protects neighboring pairs from crosstalk. Overall shield (F/UTP, S/UTP, and SF/UTP) Overall foil, braided shield or braiding with foil across all of the pairs within the 100 ohm twisted pair cable. Common names: foiled twisted pair, shielded twisted pair, screened twisted pair. This type of shielding helps prevent EMI from entering or exiting the cable. Individual and overall shield (F/FTP, S/FTP, and SF/FTP) Individual shielding using foil between the twisted pair sets, and also an outer foil or braided shielding. Common names: fully shielded twisted pair, screened foiled twisted pair, shielded foiled twisted pair, screened shielded twisted pair, shielded screened twisted pair. This type of shielding helps prevent EMI from entering or exiting the cable and also protects neighboring pairs from crosstalk. Shielded Cat 5e, Cat 6/6A, and Cat 8/8.1 cables typically have F/UTP construction, while shielded Cat 7/7A and Cat 8.2 cables use S/FTP construction U = unshielded F = foil shielding S = braided shielding (outer layer only) TP = twisted pair TQ = twisted pair, individual shielding in quads
  4. My ER is about 150 hours powered now. It just keeps getting better or rather my enjoyment of music keeps increasing.
  5. Add me to the list of gobsmacked happy listeners. My ER is about 4 hours powered on now...just sat down to listen to the very low bitrate internet stream that's been playing with the preamp off...holy sh*t. My system is no slouch but this is definitely in the component level upgrade territory. !Bien hecho!
  6. Hi Alex @Superdad, I'm anxiously awaiting shipment of ER. When you have time, would you mind updating us on when the next batches (order number ranges) will ship? Thanks much

  8. I'm finding that Qobuz volume leveling information is quite different (much higher dB) than both Roon local analyzed tracks as well as Tidal with Roon set to use the same LUFS value. Qobuz can be +6-10dB higher than the others. Qobuz also only seems to have included track leveling not album leveling. Having disparate vol leveling data in Roon makes the function much less useful. Roon folks said to contact Qobuz, which I've done but received a response that there is no vol leveling data plus no plans to add it (which is clearly wrong at least for Roon). Can you elaborate if these problems are known and are being worked on or addressed or is this new information? Thank you
  9. Rather 'it' might be made of kryptonite. Although in retrospect I don't believe kryptonite is all that dense.
  10. I've never encountered a thermal paste that would or could damage anodized aluminum. I presume that is what the case is made of. I've not received mine yet. I wouldn't expect any problem. https://www.amazon.com/s?k=thermal+paste&ref=nb_sb_noss_1
  11. I might be made of kryptonite! The nemesis of SuperDad I would guess 150g. Heat conductive tape is available on Amazon. I would expect that tape probably isn't as good as thermal paste and certainly not as good as a conductive silicone adhesive. Looks like I might get my ER in January instead of February. Hope to be pleasantly surprised.
  12. shouldn't have to change anything in Audio Linux menus. Port will auto-negotiate to 100Mb/s as the ER is fixed.
  13. I'm presuming you have an iPhone (not sure). Have you tried built-in AirPlay to the Mac Mini? It's not the 'best' quality but keeps you wireless. Otherwise, maybe the Lightning to USB adaptor would allow you plug the phone direct into the DAC. I don't have any experience with it though so confirm with others if it will pass Tidal out to USB.
  14. I've used TimeMachine for years, restored a fair number of single items as well as entire system restores without issue. By default, TM runs with a very low disk priority causing the backups to take far longer than I think they should. The priority can be changed to dramatically improve backup times. https://www.imore.com/how-speed-your-time-machine-backups
