  1. Melco buffalo
    A novel way to massively improve the SQ of computer audio streaming
    1 hour ago, auricgoldfinger said:

    Have you looked under the hood of your S100 to understand the quality of clock being used?  I'm wondering if you're considering the clock upgrade from Fidelity Audio you mentioned earlier.

     

    Both Buffalo BS-GS2016/A and Melco S100 seemed to look pretty much the same when we're comparing the PCB inside each unit, unfortunately the clock itself couldn't be seen without removing the heat sink as shown in the second link

    If that heat sink were actually removed, we couldn't really put it back on without messing with the thermal paste and therefore I'd rather stay from that.

     

    I'm expecting that both Melco N100 and S100 would share a very similar type of clock from NDK since that should be a good fit under the heat sink of S100, either picture linked below is showing that 24MHz NDK clock for NEC / Renasys µPD720201 where "X17" could be found

    I also have D10 and it's the big brother of D100 as shown in the following picture, 24MHz for NEC / Renasys µPD720210 on the left and 30MHz for µPD720231 on the right respectively

    They might have scratched the surface of the clock and there's no way to identify the model. However, NZ2520SD looked like a potential candidate to me

    Nowhere close to the performance of megabuck OCXO products like NDK DuCULoN or even MSB Galaxy, though it's still a pretty darn good deal for such an affordable option

    It might be somewhat challenging to put Fidelity Audio C5 inside S100 because of that heat sink mentioned above, it's also requiring its own PSU and therefore I'd rather leave S100 as is.

     

    OTOH, HFS1155 from JS PC Audio could be another avenue since it's so easy to replace the clock

    Dimensions of C5 are 100mm × 55mm versus 230mm × 180mm for HFS1155, that Connor Winfield accepts either 5V or 3.3V but C5 needs at least 6.5V to operate

    Of course there's also this 25MHz clock that costs as much as S100 itself

    However good sounding S100 would seem to be, there's still a lingering question for me. All audiophile switches still have low power CPUs while some supervisor modules from Cisco are much more powerful

    Since music servers with Xeon / Core i9 / Ryzen would tend to perform so much matter when compared to similar options with Pentium / Celeron / Atom, just wondering if a network bridge with Asus WS C621E SAGE + dual Xeon Scalable + Apacer wide temperature RDIMM + modified JCAT NET Card FEMTO were gonna totally smoke all switches out there

    More about this great finding from @seeteeyou. I got one of these switches and powered it with a LPS. Haven't done any listening tests yet. As already mentioned the Buffalo switch looks identical to the Melco. The layout of the board is exactly the same. Every visible component is exactly the same (i.e. the Melco does not seem to have any special/upgraded "audio-grade" parts). None of that is surprising since Buffalo and Melco are related. 

     

    It's super easy to remove the SMPS and install a 12V DC connector. Then you can power the Buffalo switch with a better power supply than the Melco. Of course the Melco switch is in a much nicer chassis, which I am sure is beneficial. The only question that remains open is have they actually replaced the clock or not? It is strange that I could not find any mention of a clock from Melco or any reviewers. I am starting to wonder if they have even done that. 

     

    Here is how the Buffalo switch looks like with the heatsink removed.

    I wish I had a Melco switch to peak under the heatsink. It's super easy to remove but there is thermal paste between the chip and the heatsink. I am glad I removed it, because the thermal paste was of pretty bad quality and not applied properly. I put some fresh Thermal Grizzly Kryonaut thermal paste on mine. 

     

     


  3. Nuc power setting

    Hi.  Looking at the last screenshot 'Primary power settings', what's the difference between enabling 'Low Power' or disabling all three options and selecting 'Low Power' in the 'Power efficiency policy' drop down?  Specifically, what's the appropriate one for simply lowering the TDP from 15w to 10w?

     

    The difference is that all 3 of the profiles - Balanced, Low, and Max - have Intel SpeedStep® enabled. See https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/BIOSGlossary_NUC.pdf

     

    I also had not realized this, and thought by selecting the Low power setting, I was done. It's only when I saw Leo's screenshot that I discovered that unchecking all 3 profiles revealed the Intel® Dynamic Power Technology drop down, and within it, you can turn Speed Step off.


  4. Format
    AudioLinux and NUC Troubleshooting and Tuning

     

     

    If you want to format a drive in headless, you must use parted.

    I understand that this can be challenging for most people.

    ---> I suggest to make a USB stick with audiolinux and use gparted (an application with GUI). Very easy to use.

     

    Please don't format in NTFS, if you can. Ext4 is a lot better for many reasons (no defrag, more solid in case of power failures, etc.)

    I asked Jussi @Miska to add ramroot to his bootable HQPlayer NAA and he quickly put it in his build.

    I like what I'm hearing.  I've only listened to a couple songs at first listen it's similar if not the same as what I hear with Audiolinux headless running HQPlayer NAA.

    I anticipated that :) see http://jplay.eu/forum/index.php?/topic/2473-intel-nuc-alikes-which-accept-jcat-femto-ethernet-card/page-2

    while most cards are around 10 dollars or even cheaper this one is 32 dolars, i bought three different ones, two mainstream and this one. the quality difference in materials was immediately  obvious

     

    under the brand name you can see where to order

    Whoa, thanks for bringing this up!  Larry and I had been discussing trying out the Intel NUC7i7DNBE board as a RoonServer:

     

    https://www.intel.com/content/www/us/en/products/boards-kits/nuc/boards/nuc7i7dnbe.html

     

    I actually selected this particular board purely because it is only 1 of 2 i7 NUC boards that Akasa is making a fanless chassis for at this time.

     

    You're very welcomed. There's yet another bonus because of these slots

    Fortunately both of them are connected to PCIe lanes, therefore we could actually give tX-USBexp and/or NET Card FEMTO a shot as mentioned below

    Three weeks ago I purchased the skull canyon nuc. As I expected Intel graphics are fine for the browser and desktop, but not for games.

     

    In anticipation of this I had researched alternatives.

     

    I ordered (from California USA) the bplus v4.1 m.2 to pcie egpu adapter on Saturday, and it arrived on Thursday via DHL.

     

    I connect ed the m.2 card, plugged in my gtx 750ti, moved the HDMI cable, added my atx power supply and it worked the first time and every time with no modifications. Even sleep works.

     

    Also good for laptops so most likely we're doing fine here

    As usual they aren't the cheapest options, PE4C-M2060A V4.1 would cost $140 and PE4C-M4060A V4.1 would cost $160 respectively

     

    http://www.bplustech.com/Adapter/PE4C V4.1.html

     

    These guys are untested at the moment but the price is right

    Even cheaper ones as linked below but they're only good for the 2280 slot with Key Type M, not to mention the awkward position with the fanless case opened
