Tested my iPod touch and damn. Great sound from iTunes with my Audeze iSine LX/Lightning Cipher setup. Yeah, I own an Astell Kern player but this is still pretty solid especially since I buy most of my music from iTunes. In any case, I think that I could pick up another iPod Touch specifically to house my Tidal streaming downloads. If you have a pair of iSines, the iPod touch/Lightning cable/iSine setup is flawless.
