I have a question about 2stepdance. Anyone ever heard background noise on it? Lately I bought a pair of Sony MDR-Z1000 when I started to notice there is background noise. The noise becomes louder when increasing volume. I use iPod Classic 3 << old version CLAS << 2stepdance. Is 2stepdance the...

Hi, Mike. I have to order JDS Lab Slip-on 3.5mm Barrel Adapter from its website. I can get Mascot from local rs online. Love 2stepdance. It is the best amp I ever used!
