but Mediabridge does not seem to produce usb 3.0    http://www.amazon.com/Mediabridge-USB-2-0-Extension-Gold-Plated/dp/B002KNI796/ref=sr_1_cc_5?s=aps&ie=UTF8&qid=1459773113&sr=1-5-catcorr&keywords=MediaBridge+usb+3.0

yes you are right, the 2-channel audio includes the missing bass when the disc has the LPCM option,  but when it has only the DTS or Dolby 5.1 then the AV receiver does not bother to merge the LFE channel into stereo . I ve read an article saying that most of AV Amplifiers below $1000 have...

Now  that i configured the Foobar2k , there are no more disconnections ! thanks guys !

yes, this was the case 

Yes, you are right. i hadn t  configured Foobar2k correctly. Now, the ifi LED lit as it should !  Thanks for your help guys !   Now back to the sound evaluation...   For instance,  a track from a CD sounds a bit better on ifi micro iDSD (using its DAC through USB connection) than just its...

I compared the ifi micro idsd against the Cayin C5 ($200 head amp)  and against the Lehmann linear ($1200 head amp which Sennheiser used to demonstate their heads before they developed their own head amp HDAV 600 and HDVD 800   For me, the ifi micro has the same sound quality as the Cayin C5 ...

well, as i said with interruptions. So, the answer is no 

playing DSD512 on USB AUDIO PRO on my mobile but the ifi LED is yellow when it is supposed to be Magenta !   then i close the usb audio pro application , playing nothing on the mobile and the ifi LED goes Magenta ! Weird !   see pics below    

perhaps, i am doing something wrong ? see my post below. thanks

i used for max 30 hrs. I would understand to hear some 5% -10% improvement after 200 hrs but i would expect to hear some of the massive improvement (as reviewers describe) right now But right now , i get no improvement at all, compared to the amplifier section alone !   I rechecked and found...

I ve been checkng out the ifi micro idsd for 5 days now. ​ ​ Well, the main thing is that both me and my wife do not notice the slightest improvement in sound quality of this ifi micro idsd as a DAC over the internal DAC of my samsung laptop np550 which has a realtek hd audio or over the...

Wow Mike !  You are definitely an audiophile. I dont consider myself as an audiophile... perhaps a bit of a videophile ... perhaps the reason being that i was never proud of my listening abilities  Yes, I ve read about Cavalli amp before ..how good it is. I contacted a youtube reviewer who...

The Lehmann has multiple gain stages and thus, probably uses a lot of negative feedback to deal with the distortion created in high energy areas of the signal, but the feedback itself creates low-energy, complex distortion artifacts down near the noise floor that destroy the micro details the...

Mike, knowning my current  gear, how much of the performance do you think i have reached so far ? in percentage please 

i want to experiment until i get the 80-90% of the performance .... i dont want to become a control freak (sorry for the expression) trying to reach the 100% lol :)
