  1. If Raspberry Pi were connected to U192ETL, there's a way to add multiple inputs via ReceiverPi so that DA96ETF could kinda work with multiple sources. Here's a similar example, GPIO connectors of Raspiberry Pi could actually accept the output of USB-to-I2S DDC https://www.my-hiend.com/vbb/showthread.php?5404-走向超值而極緻的-HI-FI電腦訊源(連載)&p=241147#post241147 Obviously that might seem to be somewhat redundant (connecting one computer to another / going from x86-based PC to ARM-based Raspberry Pi) but the purpose was more about taking advantage of FifoPi in the first place. Three inputs are available on ReceiverPi and its I2S input could be a nice addition, though it's also a good idea to consider adding both HDMIpi Receiver as well as FifoPi https://github.com/iancanada/DocumentDownload/blob/master/HDMIpi/HDMIpiReceiver.pdf Then we might connect SDTrans384 or other SD card transports to that combo https://item.taobao.com/item.htm?id=601209239990 http://www.tirnahifi.org/forum/viewtopic.php?f=15&t=4541&start=400#p90230 Regarding power supply options, this one with 5V/2A output (about €35) just came out recently and supposedly the regulators should be superior when compared to LT3045 https://item.taobao.com/item.htm?id=624841615555 BTW, multiple audiophiles in Taiwan are loving these guys from Daitron https://daitronglobal.com/product/low-noise-power-supplies https://www.daitron.com/lfs-series-low-noise-acdc-power-supply-p-1307.html https://www.militaryaerospace.com/unmanned/article/16719132/navy-chooses-150watt-power-supplies-from-daitron-for-underwater-warfare-systems-support Their LFS50A series and LFS150A series cost 12,000 yen and 17,000 yen respectively https://www.youtube.com/user/Daitoelectron/videos https://www.youtube.com/channel/UCRZCQSRWTBBWOoECoSk-1lQ/videos
  2. Some of them on SBAF tried MOS16 and then they're speculating about DA96ETF on page 5 https://www.superbestaudiofriends.org/index.php?threads/ec-designs-multi-bit-dac.7170/page-5 Something went wrong on this French forum and finally everything came to an end https://forum-hifi.fr/thread-5709-page-33.html If there were no pandemic whatsoever, maybe John could consider a tour of his products just like this https://pinkfishmedia.net/forum/threads/supercapacitor-power-supply-tour.223681/ https://pinkfishmedia.net/forum/threads/tour-of-supercapacitor-powered-ciunas-devices.223682/ OTOH, someone might decide to mess around and it's hard to tell what would happen https://www.audio “science” review/forum/index.php?threads/ciúnas-audio-iso-dac-teardown-and-failed-review.9653/ https://www.audio “science” review/forum/index.php?threads/ciúnas-dac-usb-dac-review.9788/ https://www.audio “science” review/forum/index.php?threads/ciúnas-iso-dac-usb-dac-teardown-2.9809/
  3. A computer (USB host) is necessary to be inserted between capable DDC → USB since all USB audio devices are USB slaves, that's why there're providing this device driver for their I2S-to-USB bridge http://www.comtrue-inc.com/index.php/downloads2/summary/4-ct7601/12-windows-7-10-driver I don't believe there's a feasible way to skip the computer (USB host) part, not to mention that XMOS XU208 inside ECdesigns USB-only DDC (not DAC) also requires both device driver and the computer to be present.
  4. 0.5m CAT8 Ethernet cable (Full Metal Case option for $33.45) could be a good choice as well https://www.aliexpress.com/item/4000575872860.html https://www.head-fi.org/threads/old-king-of-r2r-dac-is-dead-denafrips-terminator-plus-terminator-arrives.936310/page-6#post-15767608
  5. FYI - Greg found that Allo USBridge Sig as well as properly modified + powered RPi 2B could yield excellent results, about the same league as SDTrans384 with a decent (but not his best) PSU http://www.tirnahifi.org/forum/viewtopic.php?f=15&t=4541&start=330#p87998 http://www.tirnahifi.org/forum/viewtopic.php?f=15&t=4541&start=350#p89678 https://www.diyaudio.com/forums/vendor-s-bazaar/337859-shanti-dual-lps-5v-3a-5v-1-5a-10.html#post5809606 https://www.diyaudio.com/forums/vendor-s-bazaar/337859-shanti-dual-lps-5v-3a-5v-1-5a-34.html#post5887722 https://www.diyaudio.com/forums/pc-based/329911-getting-allo-coms-katana-dac-40.html#post5945670 Positive impressions of USBridge Sig https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/page/613/?tab=comments#comment-1009197 I guess that maybe SDTrans384 could still be fed to I2S input of ReceiverPi while connecting U192ETL to USBridge Sig then? When it comes to storage, there's always this wide-temperature + SLC option from Apacer but not everyone would like to pay so much for 4GB these days http://eflash.apacerus.com/spec/USB/Drive/EH353/Industrial-USB_EH353.pdf https://www.rutronik24.com/product/apacer/apha004gak0eg-2t/7710798.html https://www.soselectronic.com/products/apacer/apha004gak0eg-2t-307137 Though here's something used from China https://www.ebay.com/itm/Apacer-8GB-Industrial-CFIII-8GB-Extenden-Temperature-CF-card/293621554873 Patrick and others on Tír Na HiFi tried SLC cards and they seemed to be beneficial, others were actually getting larger sizes for installing Windows http://www.tirnahifi.org/forum/viewtopic.php?f=15&t=4541&start=390#p90199 http://jplay.eu/forum/index.php?/topic/2413-apacer-cf-card-extended-range-temperature-as-ssd/
  6. AFAIK Julian himself is indeed an employee of Mutec https://www.facebook.com/mutecpro/posts/2038324139582039 Did anyone actually own any USB audio devices that don't require a computer / mobile device of some sort to operate? In other words, the communications between the USB hosts (i.e. computers) and the USB slaves (i.e. USB audio devices) should rely on the device driver to work properly.
  7. https://audiophilestyle.com/forums/topic/16801-mutec-mc-3/page/42/?tab=comments#comment-611944 Recording should be supported (i.e. saving to a specific file that's stored on local drive) by Mutec while we're talking about SDTrans384 → Mutec → Computer → U192ETL in real time here. What kinda software could actually accomplish that particular task mentioned above?
  8. While I do have SDTrans384 myself, it's much better to ask @gstew and @pm325 about the I2C / I2S compatibility of ReceiverPi with Raspberry Pi / Allo USBridge Sig https://github.com/iancanada/DocumentDownload/blob/master/ReceiverPi/ReceiverPiUsersManual.pdf Here's a picture of SDTrans384, maybe either I2C or I2S could work with ReceiverPi?
  9. https://www.ecdesigns.nl/en/shop/u192etl Apparently XMOS-based devices could make use of driver from a different manufacturer as mentioned below https://www.head-fi.org/threads/topping-d30-dsd-dac-xmos-cs4398.821559/page-32#post-15232589 https://audiokarma.org/forums/index.php?threads/topping-d30-no-official-xmos-windows-10-drivers.842912/ Current driver version for XMOS is 4.86.0.42594 and they're including ASIO support already http://www.soncoz.com/uploads/1/2/7/2/127246176/soncoz_usb_audio_dfu_tool.zip http://support.bryston.com/downloads/USB Drivers/v4.86.0/Bryston_USB_DriverSetup_v4.86.0.exe If that weren't working, please try 4.82.0 instead http://jlsounds.com/uploads/JLsounds_USBAudio_v4.82.0.exe http://www.tphifi.net/drivers/topping_usbaudio_setup_v4.82.0.zip https://download.shenzhenaudio.com/Gustard/A18/Gustard_UsbAudio_v4.82.0_setup.exe https://fichiers.touslesdrivers.com/64808/Audeze_UsbAudio_v4.82.0_2020-01-17_setup.exe http://support.bryston.com/downloads/USB Drivers/v4.82.0/Bryston_USB_DriverSetup_v4.82.0.exe https://www.mutec-net.com/downloads/manuals/MUTEC_USB2.0_Audio_Driver_V4.82.0_03-2020.zip https://spl.audio/wp-content/uploads/_downloads/SPLelectronics_TUSBAudio_v4.82.0_2020-01-17_setup.exe https://techsupport.cambridgeaudio.com/hc/en-us/article_attachments/360006976798/USB2.0_driver_v4.82.0.zip ASIO support https://www.foobar2000.org/components/view/foo_out_asio https://www.foobar2000.org/getcomponent/d1b6ccaf4206736daadadd72667d49c3/658d864c9811f00c8c93d781f8f30c61/foo_out_asio.fb2k-component WASAPI output support https://www.foobar2000.org/components/view/foo_out_wasapi https://www.foobar2000.org/getcomponent/0db74e427a9da7d9477e3a6ef8864d99/c0d1ceba18d6aa494838a34485b4bc0a/WASAPI.fb2k-component WASAPI shared output https://www.foobar2000.org/components/view/foo_out_wasapis https://www.foobar2000.org/getcomponent/6e1b053a3b9e3b06eef8d25bb81d9db4/7b1a39511d0d385bb30dec8f0e09ebb2/foo_out_wasapis.fb2k-component
  10. Yeah, the license just petered out. It's so hard to resist but let's go, Roon could very well be compared to one of those attractive yet tone-deaf musicians ⁠— easy on the eyes but there's not much to hear.

  13. FYI - for those of who would like to learn more about KVM Redirection while having NIC disabled, the most popular choices of BMC (baseboard management controller) are available from ASPEED https://www.aspeedtech.com/products.php?fPath=20 https://www.asus.com/Commercial-Servers-Workstations/ASMB4iKVM/ https://www.asus.com/Commercial-Servers-Workstations/ASMB5iKVM/ https://www.asus.com/Commercial-Servers-Workstations/ASMB6iKVM/ https://www.asus.com/Commercial-Servers-Workstations/ASMB7IKVM/ https://www.asus.com/Commercial-Servers-Workstations/ASMB8iKVM/ https://www.asus.com/Commercial-Servers-Workstations/ASMB9-iKVM/ More details here, other manufacturers such as ASRock / Supermicro / Tyan etc. also got similar offerings and the keyword here is IPMI https://www.servethehome.com/explaining-the-baseboard-management-controller-or-bmc-in-servers/ https://www.supermicro.com/en/solutions/management-software/bmc-resources https://www.supermicro.com/manuals/other/IPMI_Users_Guide.pdf https://www.asrockrack.com/support/IPMI.pdf https://github.com/openbmc/openbmc Alternatively, AMD also implemented KVM Redirection via Desktop and mobile Architecture for System Hardware (DASH) but it's severely limited to the BIOS settings only. https://www.dmtf.org/sites/default/files/standards/documents/DSP1076_1.0.1.pdf https://www.reddit.com/r/MeshCentral/comments/d7a7ud/does_meshcentral_have_support_for_dash_amd/ I won't talk about different implementations of Broadcom and Realtek but we could still take a look here https://www.reddit.com/r/Amd/comments/bic7yj/what_is_needed_for_bios_level_vnc_remote_access/ OTOH, we could do much better with vPro from Intel instead https://web.archive.org/web/20110402071445/https://software.intel.com/en-us/blogs/2011/03/21/intel-vpro-technology-with-intel-amt-what-to-look-for https://web.archive.org/web/20120110140544/https://software.intel.com/en-us/blogs/2011/12/08/intelr-amt-kvm-not-working https://msp.intel.com/assets/Top_10_vPro_Questions.pdf https://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide/default.htm?turl=WordDocuments%2Fkvmonaplatformwithdiscretegraphics.htm Basically we'll need the CPU + Chipset + NIC (wired / wireless) trifecta here, CPU itself must have integrated graphics or else it ain't getting anywhere https://www.intel.com/content/www/us/en/products/processors/core/core-vpro.html https://www.intel.com/content/www/us/en/products/docs/processors/core/8th-gen-vpro-processors-brief.html https://www.intel.com/content/www/us/en/products/docs/processors/core/9th-gen-vpro-processors-brief.html https://www.intel.com/content/www/us/en/products/docs/processors/core/10th-gen-vpro-processors-brief.html Here's a list of chipsets with vPro Here's a list of (wired) NICs with vPro Here's a list of (wireless) NICs with vPro I also talked about specific NUC models with vPro a month ago https://www.intel.com/content/www/us/en/support/articles/000031997/intel-nuc.html https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/page/657/?tab=comments#comment-1054055 Just use the latest version of MeshCommander (Windows) or wsmancli/wsman (Linux) for the remote control part, I also mentioned both of them in my previous post linked above MeshCommander https://www.meshcommander.com/meshcommander http://info.meshcentral.com/downloads/MeshCmd/MeshCmdUserGuide.pdf https://www.facebook.com/notes/intel/meshcentral-basic-remote-desktop-from-a-web-page/459291082067/ How to Remotely Control Your PC (Even When it Crashes) https://www.howtogeek.com/56538/how-to-remotely-control-your-pc-even-when-it-crashes/ How To Control Remote Computers Using Intel AMT https://www.prajwaldesai.com/control-remote-computers-using-intel-amt/ Configuring remote KVM access https://help.ivanti.com/ld/help/en_US/LDMS/10.0/Windows/vpro-t-remote-kvm-access.htm Finally we'll also need to fool the HDMI output with a dummy plug or simply change some BIOS settings, then we don't need to attach any monitors at all https://www.adafruit.com/product/4247 https://www.amazon.com/Dummy-Headless-Display-Emulator-Headless-1920x1080/dp/B07Q3KDZ9V Enabling "Headless display emulation" BIOS Option on Intel AMT Platforms. https://www.win-raid.com/t4917f39-Enabling-quot-Headless-display-emulation-quot-BIOS-Option-on-Intel-AMT-Platforms.html HowTo Headless Intel NUC vPro AMT https://wiki.networksecuritytoolkit.org/index.php/HowTo_Headless_Intel_NUC_vPro_AMT
