I asked this on the dx50 thread but thought i'll ask here as well.
Would the dx50 be a significant upgrade in terms of sq over a rockboxed sansa fuze v2 that i've paired with a fiio e17. im using the line out of the sansa so the digital to analog conversion is done by the e17. i understand the e17 has the same dac chip as the dx50 and x3.
Will only be using with westone 4s.
