  1. IMHO it's also quite interesting to notice yet another "unwritten rule" that sponsors could openly "make fun of" non-sponsors (i.e. competitors) outside sponsored forums https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/?page=437&tab=comments#comment-896822 One more shining example https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/?page=361&tab=comments#comment-860498 It's also nice to keep commenting on the OCXO inside another competitor's products while the devil is in the details https://audiophilestyle.com/forums/topic/55202-article-quick-take-the-linear-solution-ds-1-network-streamer/?page=2&tab=comments#comment-914669 Sometimes I just found it so much fun to read certain impressions but we couldn't really tell if some sorta "permanent" loaners were involved since I was struggling to find any kinda disclosures https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/?page=412&tab=comments#comment-892714
  2. Speaking of wireless storage, Pioneer made something called Stellanova and basically it's kinda like Wi-Fi dock of some sort but you must install their own apps in order to access USB drives and DACs via its wireless network https://darko.audio/2015/10/everyman-hifi-at-fujiya-avic-2015-pioneer-stellanova/ Even third party products like Chord Hugo could be connected There's a much cheaper model with only 1 USB 2.0 port but we could actually power that with a pair of A123 LiFePO4 plus LT3045 https://www.amazon.co.jp/Pioneer-パイオニア-IEEE802-11a-対応ワイヤレスドック-APS-WF01J-2/dp/B01L0ZRI2G https://www.ebay.com/itm/LT3045-four-parallel-regulated-power-supply-5V-2A-Upgrade-LT3042/273135946356

    Could the USB port of UPL provide enough power for wireless flash drives such as this 32GB one for $18? https://www.sandisk.com/home/mobile-device-storage/connect-wireless-stick https://www.amazon.com/SanDisk-Connect-Wireless-Stick-Flash/dp/B00ZCFYT5K Hack a Sandisk 32G Wifi enabled flash drive https://forums.hak5.org/topic/30273-hack-a-sandisk-32g-wifi-enabled-flash-drive/ SanDisk Wireless Media Drive Root Crack(and other useful info) https://forums.hak5.org/topic/35884-sandisk-wireless-media-drive-root-crackand-other-useful-info/ SanDisk Connect 32GB Wireless Media Drive root https://forums.hak5.org/topic/41977-sandisk-connect-32gb-wireless-media-drive-root/ We could always add our own USB hub if external power were necessary, though UPL itself might / might not be able to read the files off those somewhat "special" drives. If everything were going as planned while the USB stick could still be accessed locally by UPL and remotely by another computer simultaneously, it could be worth a try to write some relatively simple scripts to manipulate the playlist on the fly. Of course we still need to figure out how slow it REALLY is https://www.theregister.co.uk/2016/08/26/a_usb_stick_as_a_file_server_weve_done_it/ That might seem to be a bummer but thankfully 44.1/16 *.wav files ain't THAT large to begin with. Even if replacing files on the fly weren't feasible, hopefully we could at least read stuff like filename (i.e. title of each track) / folder.jpg (i.e. album art) remotely. Does it sound like something that's doable?
  6. That's cool, many thanks for sharing your experiences with graphene. These guys aren't regulated and that's why we could introduce our own linear regulators 7.4V https://hobbyking.com/en_us/graphene-5600mah-2s2p-hardcase-w-5mm-female-bullet-connector.html https://hobbyking.com/en_us/graphene-6000mah-2s2p-hardcase-w-5mm-female-bullet-connector.html 11.1V https://hobbyking.com/en_us/turnigy-graphene-5200mah-3s-15c-w-xt60.html https://hobbyking.com/en_us/turnigy-graphene-6000mah-3s-75c-lipo-pack-w-xt90.html 14.8V https://hobbyking.com/en_us/turnigy-graphene-5000mah-4s-75c-lipo-pack-w-xt90.html https://hobbyking.com/en_us/turnigy-graphene-professional-10000mah-4s-15c-lipo-pack-w-xt90.html 18.5V https://hobbyking.com/en_us/turnigy-graphene-4000mah-5s1p-65c.html https://hobbyking.com/en_us/turnigy-graphene-6000mah-5s1p-65c.html 22.2V https://hobbyking.com/en_us/turnigy-graphene-6000mah-6s-75c-lipo-pack-w-xt90.html https://hobbyking.com/en_us/turnigy-graphene-professional-8000mah-6s-15c-lipo-pack-w-xt90.html There were quite a few discussions about STUDER900 and that could be a good candidate for regulating the output of Turnigy Graphene https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/?page=422&tab=comments#comment-894862 https://audiophilestyle.com/forums/topic/55159-best-alternatives-lpsu-to-paul-hynes-sr7/?tab=comments#comment-913447 https://www.diyaudio.com/forums/power-supplies/297610-low-noise-pre-amp-dac-power-supply-mje15034-tl072-regulator-based-studer-900-a.html#post5253455 https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/?page=359&tab=comments#comment-860030 https://www.diyaudio.com/forums/power-supplies/297610-low-noise-pre-amp-dac-power-supply-mje15034-tl072-regulator-based-studer-900-a-2.html#post5302522 We could find quite a few sources of pre-built units as well as PCBs https://www.audiophonics.fr/en/linear-regulated-psu/module-alimentation-lineaire-regulee-mje15034g-faible-bruit-5v-a-24v-2a-p-11131.html https://www.aliexpress.com/item/STUDER900-Regulator-linear-power-supply-DC12V-2-5A-30W-tube-Preamplifier-Audio-Decoder-Professional-Power-Adapter/32822732608.html https://item.taobao.com/item.htm?id=529559559576 https://item.taobao.com/item.htm?id=529758280774 https://item.taobao.com/item.htm?id=546056034957 https://item.taobao.com/item.htm?id=555625624270 Usually a single board seemed to be limited to 2A or so, though DIY options could go quite a bit higher than that.

Its 20V output should be good for Dawson Canyon such as NUC7i7DNBE, while 14.5V should be a good idea for other models since they're only good for 19V ± 10% https://forums.intel.com/s/question/0D50P0000490WeYSAU/is-a-20v-maxoak-50ah-battery-ok-with-a-nuc
  8. Pulse HB seemed to be a bargain when compared to this guy https://www.chord.co.uk/product/chordmusic-streaming-cable/ I couldn't afford a pair of Pulse HB interconnects myself so I just ordered two Pulse HB coaxial cables instead. Maybe one day @greenleo and I could visit @hols with my Pulse PB so both of them could go between Blu2 and DAVE.
  9. Obviously not a fanless setup by any means, though this particular work of art really made something special outta NUC8i7HVK https://www.chiphell.com/thread-1901382-1-1.html FYI - here's a Chinese seller who made something for NUC6i5SYH with a water cooler, maybe similar stuff for NUC8i7HVK would cost more than 82 RMB but that should be no biggie https://item.taobao.com/item.htm?id=546257572419

    SMSL D1 - the chinese dark horse?

    Hi Piero @hifi25nl, would you please kindly add the following USB_ID so that @guiltyboxswapper could try native DSD with NUC + AL later? case USB_ID(0x152a, 0x85dd): /* SMSL USB DAC */ case USB_ID(0x152a, 0x85de): /* VMV USB DAC */ case USB_ID(0x152a, 0x85df): /* SABAJ USB DAC */ I found them after downloading the driver for SMSL D1 here http://www.smsl-audio.com/download.asp http://www.smsl-audio.com/Upload/download/20180706111408723.rar Oops, I just saw that's already included in the latest version since December 7th https://github.com/torvalds/linux/blob/master/sound/usb/quirks.c case USB_ID(0x152a, 0x85de): /* SMSL D1 DAC */ https://github.com/torvalds/linux/commit/2acee31cce656cca9e81072c330c1322e1376155
  14. Piero @hifi25nl already asked for DSD1024 support under Linux but Jürgen @lintweaker didn't seem to be interested https://github.com/lintweaker/xmos-native-dsd/issues/28 I grabbed a copy of the driver of Spring 2 and found something relevant, I guess that quirks.c could be modified first https://github.com/torvalds/linux/blob/master/sound/usb/quirks.c case USB_ID(0x20b1, 0x3036): /* Holo Audio USB Digital Interface Gen1 */ case USB_ID(0x152a, 0x87c0): /* Holo Audio USB Digital Interface Gen2 */ case USB_ID(0x152a, 0x87c1): /* Holo Audio USB Digital Interface Gen3 */ Then something else like an additional patch might be created in order to get things going, most likely there will be even more necessary changes but I dunno https://github.com/lintweaker/xmos-native-dsd/tree/master/SRPMS/patches/kernel FYI - I found that driver here https://pan.baidu.com/s/1hj5cTymhtF8Qr5zy1_YZCQ https://item.taobao.com/item.htm?id=527818416876
  15. https://www.computeraudiophile.com/ca/ca-academy/computer-audiophile-pocket-server-c-a-p-s-v4-introduction/ We could pay Intel that kinda money to make a prototype of something VERY special, most likely that's a better bet than Asus or Supermicro etc. I dunno, attacking the latency side while bypassing the CPU as much as possible should be a good place to start PCIe Peer-2-Peer https://github.com/sbates130272/donard https://github.com/sbates130272/linux-donard https://github.com/sbates130272/linux-p2pmem https://www.abaco.com/download/pci-express-peer-peer-interconnect GPUDirect RDMA https://github.com/NVIDIA/gdrcopy https://developer.nvidia.com/gpudirect https://github.com/Mellanox/nv_peer_memory A quality PSU with top-notch performance is still relatively hard to come by, we still dunno if Dr. Sean Jacobs' flagship or TLS Reference 1 were as good as SR7 DR or otherwise. Is it realistic to expect plenty of us who are happy to share the costs of R&D in terms of making the "best" motherboard for AudioLinux? We'll have to find out if Neutron Star 2 were even better than stuff like Connor-Winfield etc.
