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

MHd-Q7を開けたら、好奇心からコンデンサーを替えたくなってしまい、コンデンサーを交換してしまいました。

結果は元のと比べて厚みのあるふくよかな音に変身しました。
元の音に厚みやふくよかさを加えた音ではありますが、クリアーさやストレートな音は継承しております。

改造によって、元のオルトフォンの味付けとは変わってしまいましたが、私好みの音になり満足です。

試す方は少ないと思いますが、工業グレードのコンデンサーが気に入らない方は是非(笑)

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.

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.
