Very bad hissing

Application idea is great but interface is bad sound have way too much hissing noise I used Shure SE530 + iBasso D10 for DAC & Amp with gold connector between my iTouch and the D10 but sound is so inferior
If you do classical you do them for music saavy people so get serious and try to clean it or do it in larger format not the old midi format
