Same here...my experience is the same as Puremusic. For the longest time I held off on using anything but the good quality cord supplied with the Purepower unit thinking that with the regeneration+storage into batteries and SOTA cord could not possibly help. I was dead wrong. Improved macro and micro-dynamics; greater resolution and fullness; tighter and more powerful bass; even better sound stage and imaging; improved coherence and refinement; enhanced musicality and realism and energy.
