- Darkness of background : I only listen it with an Headphone, so cannot compare with IEM's
- Separation and layering : The DX 240 is better
- Now by using it with my ZMF VC, I prefer the M8, less fatigue, less agressiv, more relax, but I plan order the Amp8 MK2 and expect to obtain a nicer sound with the iBasso, but with my Kennerton JM Edition the DX 240 is better.
- For my opinion the best purchase is the DX 240, the price value is above the M8.
- The main sound signature différences are the Dynamic and Clarity, higher in the DX 240 (with an Amp8).
