Okay, thanks for answers so far,
Anyway i'm not in a hurry, so i can wait till the test of E70V.
My current DAC sounds pretty good to me, (which is of course totally subjective, i know) , but it's also pretty old, >4 years or so, and i bought it back then for 140€, it's a NuPrime uDSD, about the size of a package of sigarettes, and sinds pretty good to me, again pure subjectively, i have no idea how it would measure.
I'm sure given it's age and even then already lowish price it will be obliterated soundwise by all the latest offerings in the 300~500 $ or € category tested by Amir lately.
Price-wise my current dac is definitely not on par with the rest of my equipement.
That said, in all those years it Almost never let me down over it's usb connection, and when it does it's more likely my labtop at fault.
Anyway, hoping for a test of the E70v the same, even if the conclusion would be " buy either and be happy with it, cause there is no audible difference" .
