I was just listening casually with arrow 4G and decided to swap to MHd-Q7, boy the difference in sound is clear, crystal clear! MHd-Q7 sound stage has more height, the same width and bitter depth. It has much better bass. 
 
Truth be told I do not know the impedance of the IEM I am using (R-1L) so it could be just that but the difference is audible.

If there was a way I could get ride of the hiss without using resistors I would really need non of my other amps. Does anyone know what causes the hiss? Is there a part I can remove to fix it?

I finally was able to track down the mod I posted a while back, I tried using google translate but it came out wrong can someone translate lossly on what exactly the mod does, thanks

It just says, change the condenser

thanks, they seem to have relocated the caps on the board and added that green cable which I am not sure what it does.

Finally have an idea what is the probable cause of the noise, it is poor grounding. That mod I posted before is grounding mod.

Have you tried the mod?

No I have no soldering experience, I hope I can convince my cousin to do it for me.

I've taken new appreciation towards MHd-Q7. I find it that it is best suited for dynamic based IEM/headphone. Its only flaw is the hissing with balance armature that is only it.

Got to figure out what this mods do. MHd-Q7 gives me the sound I want, I must find a way to remove the hiss.

MHd-Q7 came to cardas model 1 rescue, I am liking what I am hearing. I have started reading into cap replacement for MHd-Q7 and whether that can improve the quality of the sound. MHd-Q7 deserve more attention.

Hello HF friends. Any update of this little audio gem? I have one and works very nice with my Iphone 6S using Sydney Audioquest Mini to mini cable. It works great with Grados and IEMs.

 

[audionewbi]

Yes this thing is amazing provided you pair the right IEM. I’m missing mine, I guess I’ll be using it tonight
