Hi guys,   based on your opinions, prepared a "short" list: Sony MDR-1ABT (LDAC) and AKG K845BT (many positive reviews in Internet). Will keep you informed.   BTW I also owned 2 pair of Sennheiser RS 180. In my view good headphones for watching movies at night but not for music.

elektron Thans a lot for you advices. I definitely will try MDR-1ABT  Honestly I am not a big fan of Sony headphones ... hope somebody will advice another Bluetooth models from AKG, JBL, ....

Hi guys,   I am using NWZ-A17 with JBL J56 BT over Bluetooth for one year and more or less happy with this pair :) Anyway looking for other headphone, hope to achieve better quality from HiRes records.   Questions: - which Bluetooth version (3 or 4) in NWZ-A17? - could you, please...

I' ve connected Raspbbery Pi2 to the Gustard U12 - under RuneAudio works great without any problem. 

Strange... I've installed without any problem with following steps: 1. Return Windows server 2012 R2 to the standard mode with GUI 2. Remove Gustard native drivers through control panel. 3. cmd (Run as Administrator) 4. Enter the following command and press Enter: BCDEDIT /Set LoadOptions...

Also use Windows server 2012 R2 (Audiophile core edition) + JRiver, recommend to use WaveIO driver modified by Chodi: http://www.speedyshare.com/RXMDH/Luckit-2.23-for-Gustard-U12.rar With this driver you have ability to adjust the latency.   Besides you need to enable unsigned driver...

Thanks a lot! Working now!

Tried to run U12 with Daphile (www.daphile.com). I see in Audio device "xCORE USB Audio 2.0", screen display show correct sampling rate ... but no sound at all. If somebody use Linux, please share your experience.

Believe me, I read the entire thread before asking, try to re-read my first post. Expected to see specific recommendations on capacitors replacement and got them as well as other tips.

Great! Thanks a lot! This is what I expected  Will start with pulse transformer replacement and caps. ​Unfortunately mouser doesn't send to my home country Ukraine, will try to find another source. Thank you again!

I am using AudioQuest Carbon USB cable.   Frankly speaking I don't see the reason to use expensive cables for 170$ converter. Maybe it makes sense for Berkeley Alpha USB but not for Gustard U12, just my opinion   Waiting for advice/tips for possible mods.

ok, I will describe the full config: I am using dedicated MusicPC (Gigabyte J1800N-2H + PPA Studio Audio Grade USB 3.0 PCIe Card, Wesena ITX4, Server 2012 audiophile core edition + JRiver) with 2 PSU (linear for MB + impulse for HDD/SSD) -> NAD M51  -> Ayre V-3x  (XLR) -> Sonus Faber Cremona...

Hi guys, I got mine U12 week ago (as NY present ) to paired with NAD M51 DAC and compare with build-in USB. The achieved results were good enough, even better than expected  Anyway I am thinking about mods. As far as I see there the main route is: - digital transformer pulse PE-65612NL ->...
