Gents, I think I have just had a light bulb moment!
For a few days now I have been thinking just how awesome my DX100\JH16 combo sounds. Its hard to describe, but everything sounds much "fuller" with a subtle but noticeably increased sound stage and air. Mids and Bass have much more weight and impact to them and seem more forward. Although, the JH16 can't be called "weedy and thin", the sound I was getting before was much "thinner" and more analytical than it is now. Now my music sounds just that bit more analogue and warmer.
I have just noticed that my Gain is set to High!
So it seems that my combo works REALLY well on the High gain.
I'm not sure if this is the right place to ask these questions?
Can anyone explain to me why it should sound so much better on the High gain - even at a lower volume? (in simple laymans terms ;-) )
I had always assumed that the High gain was for hard to drive headphones and not for improving IEMs?
What exactly is Gain?
Can the High gain damage my JH16 ?
The only slight downside I have noticed is a slight hiss in between tracks and on very quiet tracks.
Have I finally understood why people choose to audition and use different amps for headphones?
I have been trying to sell my JH13 as I found them too mid\bass light....maybe I will have to give them a go on the DX100 with the High gain now!
All my experience so far has really been with DAPs and IEMs. I do have an IBASSO D10, but have never really noticed this dramatic improvement in the sound.
I tend to prefer high gain for everything I have. Some manufactures state that the sound is the same, regardless of gain, but IMO, it is different and prefer high gain, while bringing the volume back down. The way the gain is handled in the unit affects the sound. How various manufactures choose to do this varies.
