Hello, this is for a week old Xin SUper mini V3. It is in perfect working order and has all of the upgrades mentioned: larger power caps, digital volume, and line out. Im selling this because Im trying to get ServingInEcuadors Sonic Adventure :-D and my new headphones (HD 580s) don't work well with the tiny Supermini. I am asking for $90.00 shipped for this nice little piece of work. It also comes with radio shack gold plated mini to mini plug so you dont have to go out and buy one yourself!
