I'm the first owner of this Tomahawk and I've barely gotten the chance to use it in the 3 years that I've owned it. I'm not sure if it has been fully burned in yet (probably 100 hrs of white noise and 20 hrs of listening). It has the serial number T606 and it is black. I'll be shipping it with the original box with the original instructions. Price: $200 w/ Free Shipping in CONUS Thanks!
