  1. Here is a simple way to do this. With one nvme card I'm sure it's safe to pull the power on the fan and leave the cover off. https://www.asrock.com/mb/spec/product.asp?Model=ULTRA QUAD M.2 CARD

    batteries?

    Lol, you really must have graphene balls to make such a statement.
  4. Gsquared, You need to setup the optane drive. I think I shared the partition sizes earlier. There are dozens of ways to do this. Yes, any partition you don't copy from the AL image needs to be formatted. I'm on my phone on vacation at fhe moment. Maybe someone else can provide the details in my absence as the details are at home. Thanks, Larry
  5. Rajiv, Nice report and lots to think about here. Off hand, it would be interesting to have you set the NIC on the NUCI7DNXX to 10 mbps and compare that to the TLS-DS1 box both running Roonbridge. I recently terminated my own Cat 6a Ethernet cables. OMG, they sounded great. Later I realized I'd screwed up, and crossed wires meant the cable was running at 10 mbps. They have been left that way, but now I'm running wireless so don't use them. More to come.
  6. Especially one with a well groomed library!
  7. Termius runs on my Android tablet, which probably has a built in ssh as well, and it's kinda slick with easy to resize text, good keyboard, easy to setup hostname and security details. Recommended for Android!
  8. Hi Forehaven, There are people that are looking for new tweaked out servers that are not NUC based, so the coffee lake and z370 type motherboard seem to meet those needs best. This allows tweaking with special nic, USB cards and clocks in a way that is not possible on a NUC. Will these solutions sound better then a NUC, I don't know. How many angels dance on the head of a pin?
  9. Usually 12gb for boot, root and iscsi lun, 16gb for roon.
  10. My servers all ram boot the AL OS from a 32gb Optane stick. This is especially fast with Optanes crazy sequential read speeds. At startup the Roon scripts are pointed to an Optane based Roonserver software and database in a separate optane partition. This way any database or software update is stored in non volatile memory. Everything else runs in ram. Music is either fed from a nas or external usb disk. For the traffic generated by roon, optane is ideal as it is the fastest nonvolatile memory available for short bursty traffic. We could debate why a ram disk based OS sounds better then a demand paged OS all day long. For most of us it just does, and we don't know why. With AL it is trivial to test this one way or another just by turning ramboot on or off at boot when the yes or no question is asked so people can have at it. I still prefer zero nonvolatile storage in the endpoint, so the Usb stick boot and remove method or iscsi boot from server is preferred. Unfortunately Iscsi over wifi is unavailable, so the latter only works with wired connections. Iscsi will be revisited once the ether regen arrives.
  11. My mistake, I did indeed listen to the stock smps, and you are right, not bad. I did indeed try direct dsd256 with good results. I'm thinking the ifi performance over the RME is due to the the lps1.2 and its fast response to current demand. Unfortunately the RME would not run with the lps1.2. Yes, that firmware bug on the ifi is annoying and is the reason I'm shopping for a new dac.
  12. Hi Luisma, No, I have never run Ubuntu here. My machine/OS history was an embedded processor J1900/AL back in 2013/14, then a i7-6700k system running Windows/Roon/Hqplayer, and this past August the replacement of Windows with AL headless on the server and the addition of the NUC/AL headless endpoint. Now, depending on the day, I may be running a Celeron, Pentium or I7 endpoint and/or a NUC i7 or i7-6700k server. I expect to replace the i7-6700k and z270 with a modern coffee lake and related motherboard in the next few weeks. Having run Hqplayer for many years, I am surprised that Roon running in native mode sounds so good. In that period the Roon people were clearly enhancing their product and it delivers. So, at least at the moment, I'm running a low tdp NUC endpoint and a high tdp server configured in low tdp mode, all bit perfect in Roon. I don't know where things will take me next. I hope this answers your questions. Please do contribute to this thread. It going to be pretty boring if I'm the only poster. Larry
  13. John, I think you are referring to my ownership of the original microIDSD DAC prior to owning the Black Label. The Silver IFI DAC replaced two ESS based DACs, an Auralic Vega and a Mytek Brooklyn. Upsampling with Hqplayer to DSD512 with the microIDSD beat both of these much more expensive DACs. Now, I am not upsampling at all and the BL sounds great. The RME DAC has a terrific feature set, but I just couldn't get it to the same level. It was a relief to reinstall the IFI and hear that the musicality was still there. With a Lush cable and three lps1.2s powering the NUC, ISO Regen and Vbus to the DAC it is not an inexpensive solution, but it sure delivers.
