Is Fiio E10(not E10K) supposed to be silent at level 0 with low gain setting? I've tested it with  Asus K55VM laptop (volume set at full) and Grado MS1 & Denon AHD2000. It sounds quite loud even with volume knob at 0 and low gain.

Where Audinst HUD-MX1 stand in comparison  to E17??

 

Well I checked inside too.. number on the driver and other things, everything appears to be alright, listening to "Petrified"  by fort minor and whole headphone is kinda shaking 'cause of bass.. I doubt its a copy.. it just sounds awesome..

Here you go :                    

how do you know that they are fake?? by price?? well mine are sounding way to better to be fake.. but still looking for some solid proof..

Anyone??

Was there any serial number on the back?

I've bought a pair of Denon AH-d2000 which were on sale on ebay, slightly used. When I heard them, they sound much much better than my Audio Technica ATH-M35. But I'm unable to verify their genuinity as there is no serial number on the back of the pack, may be somebody has tampered with it, on...

Found something useful here http://www.binkster.net/extras.shtml#cd, played track 6 and 7 and I was confirmed that u were right..

sounds relieving, any test to confirm this? Well I am playing LP FLACs since then to observe any crackling sounds and looks likes any absurd sound that comes, is the noise from the song, not from the headphones.. but still need a confirm test for this.. 

I bought Audio Technica M35 2 days ago and today I accidentally played an unusually loud sound when laptop's audio was at 100%. That sound consisted of frequencies > 8khz. I have not observed any adverse affects after that but could have that damaged the speakers(to a small extent though)...
