received my RCA->3.5mm cable from wotiyo for my C3, 2 days ago. after fixing it up, i feel that there is an increased in clarity (pardon my insufficient vocabulary in audiophile terms as i am also a newbie). wotiyo's workmanship is very good  i would recommend these cables for any C3.

have yet to experiment with speaker cables tho. bro wotiyo, u got any speaker cables?
