I don't know, assume it's another integrated hub, only Ugoos can answer. I have to repeat there are no external USB hubs anywhere near RPi or Ugoos box and DAC is always connected directly to integrated USB port. Regardless of what the "Terminus technology" device is, Ugoos is a secondary...

Yes, I have tested the DAC later with another Linux device(Ugoos-AM6) to confirm the problem is not limited to 1 device(Rpi3) model/vendor/kernel. In both cases DAC plugged directly into the device without external HUB, to the same USB port the other USB DAC was working. Hubs listed in lsusb...

Thank you guys, update to f/w 1.0.3 wend successfully. Tested the USB input with my linux-based streamers again but unfortunately the BR13 wasn't detected as an USB soundcard. Device also not detected by "lsusb" command. Menu controls, display and BT streaming work when connected with the Linux...

Thank you, I'm afraid it could be related. Today I have tested again with another Linux device - CoreElec box player with the same result - DB13 not detected as audio device, see screenshot below. My other DAC models (Yulong DA8 and Topping E30) are detected when connected via USB so I'm more...

Have upgraded firmware and tested my BR13 via Windows/USB and BT/LDAC modes. Must say I'm happy with the audio quality, it's a surprisingly good device for the money. Later I came across a problem when tried to use BR13 in USB mode with my Moode RPi streamer. The device was not detected as USB...

Could not resist the BF offer and bought the device yesterday :) Now have to wait for 3 weeks until it arrives. Noticed that a firmware update has been released with volume fixes: https://forum.fiio.com/note/showNoteContent.do?id=202311221824518791075

How about recently announced Lenovo Vibe X3? http://www.gsmarena.com/lenovo_vibe_x3_launched_in_china_in_three_versions-news-15033.php   "There's a total of three Texas Instruments OPA1612 amplifiers, a Cirrus Logic WM8281 codec for noise and echo cancellation to handle the input from the...

Thank you for your advices guys. I have received several replies from Yulong support, all are directed towards idea I am facing grounding loop issue. So today I have tried to test whether the noise issue can be caused by the grounding loop. For now I'm not so sure it is the problem reason, I...

Thank you for the suggestion. I have sent an e-mail message to the 3 addresses (wsz0304@vip.163.com, yulongaudio@foxmail.com, yulongaudio@qq.com) with request for help and link to my head-fi post containing problem description. I am interested into whether someone will actually reply.

Hello again, I want to report that the sound quality of my DA8 unit has finaly improved, yet it took very long time (nearly a year) until it finally bested my internal soundcard in SQ. It remains a mystery to me how it's possible that it needed so much time to break-in. Unfortunately it's not...

I have Z87 chipset motherboard without USB DAC support, seems newer generations have this function. Is there some inexpensive PCI-e USB card which support usb power-off function? I don't want to spend 400-500 EUR for an audiophile card like SOtM Audio tX-USBexp, but some cheap card supporting...

I'm too interested into some reasonable priced cable replacement, found just this cheap silver plated cable recommended in the Australian tour thread: http://www.ebay.com/itm/281199686467?euid=ca5f55e18cac42ca850117b998caf4f8&cp=1

How they sound when used with low volume? I use HD650 for that now, I like to listen on low volumes. Can they be used for that purpose? Thanks

Thank you for your opinion. Yulong DA8 amp is quite capable, should be able to handle the can. Anyone able to comment about low volume listening with DT-150 (vs HD6x0)?

Hi there, I'm looking for some musical, natural sounding, low leakage closed headphones to complement my HD650s and stumbled upon this interesting retro-looking Beyers thread. Many excited owners here made me to consider DT-150 very seriously, but I'm not yet 100% sure they are the best option...

I would also be interested into comparison of sound leakage. Choosing a closed headphone with velour pads is not an easy task, now I know it too. I may be more inclined towards K271 MKII/K272 (like weaker bass), but if the leakage is higher I may consider the DT-770 Pro, or maybe DT-660 which...

First I'd like to thank you for your response. I would be very grateful if you could somehow manage the test at your friend's house. My concerns with K553 are headamp impedance issue (they are quite sensitive @114dB) and possible aggressive highs (saxo, trumpets) or peaks you mentioned. In...

Project86, do you think these could be fed by Yulong DA8 amp without background noise (K553 impedance is only 32 ohm)? I need some closed-back alternative to my HD650 and considering K553 as cheap option and more expensive options like Oppo PM-3 (26 Ohm) or Alpha Dogs (50 ohm)...All are low...

Thank you for your suggestions and advices, I really appreciate it.   I have already tried quite a few things, switch power outlets, power strips/UPS, USB cables (both with pins 1&4 covered with tape). My Haswell PC with Foobar2000 and Yulong on the same power strip or on separated, still not...

Thank you for the confirmation. So it's not an indication of anything seriously broken.   The main problem I experience with my unit are frequent changes of it's sound quality.   It sounded very bad when new, prominent highs with background noise, recessed mids and weak muffled bass, my...

Hello guys, I have some problems with inconsistent sound quality of my DA8 unit, changing every few hours. I tried to communicate with the seller, but he was not easy to convince that the problems I experience with my unit are serious enough. I would like to be sure whether my unit is defected...

Hope the problem will be resolved for you soon. I have planned to buy USB cable from them too...now I'm not so sure. In any case thank you for warning about possible problem.

Thank you for your advice, I have tested upsampling to DSD128 and it sounded really good (and differently from PCM), for me "SDM Type C" sounded probably best (least fatigue).   In between - after more burn-in (180 hours just passed) the sound of my unit became nearly perfect, the harshness of...

Hi all, new owner of DA8 here. My unit is still in burn-in - 90 hours passed just a while ago :) Sorry for my english, not a native speaker, but I'll try my best to explain.   Brand new unit sound was quite raw with too much heights for my taste. Burn-in has helped a lot, sound got smoother...

On this Hungarian website: http://prohardver.hu/hir/asus_xonar_essence_stx_ii_7_1_hangkartya.html I have found information that the card should be available from the middle of April for a price approx. 200 EUR.   If it's true, then the price is little higher than I have expected, probably...
