i'm assuming the M11 and M7 are the same for jumpers...
but when you remove the jumper from PLLEN it ENABLES the PLL!!!!
so if you have a good clock source, you should definitely DISABLE it by putting a jumper on it!
also, Dither is default to having no jumper... i believe adding it will disable it as well.
But I should try again, before I didn't like the sound.

also the m7

there is a common confusion about the DSP...many sources have it wrong...but PLLEN is default with no jumper and means PLL is enabled....
so..... try it without unless your source sucks.
so unless you're running bone stock from a crap usb source...turn off PLL if you have a good DDC, or using hdmi i2s with good ddc.
you have PLL clock enabled in your photo. and maybe it does sound better if your source isn't good enough, it would sound better enabled.
you have dither disabled, and you're the first person I know that has preferred it to be disabled. maybe if you are using Jriver's DSP data dithering it might make up for it... I need to experiment with this more.
I will try stopband -90db but oddly seemed to be best for me at -50db.
try some of the things I mentioned and let me know what you think!
the M7 and M11 are "similar" but dont' have the same signature.
So either way, we may just prefer different settings based on that alone.
but seems most people that have m7's will choose the same settings as those with m11's.
Both are top notch dacs.
