I have a 3 month old red C5D DAC/amp for sale that has been very recently check out by JDS Labs to be in fully working order. I had a problem with the 4th generation iPad, but a swap with another new C5D eliminated this particular unit as being the problem. My iPad has a bad Lightening socket. It is a portable battery operated unit that has no problem powering my Beyer 250-ohm DT880 headphones. The price is firm and will only be shipped to the lower 48 USA states. This is an out of the box unit that uses its USB connection for power. You can search head-fi or the JDS Labs website for specifics.
Since my iPad has a bad Lightening socket, I cannot use it. So someone else can use this at my reduced price. This item is not subject to return. This sale is final. I need the money for other financially pressing matters. I am willing to split the shipping costs. And this unit has not been customized, for it still has the JDS Labs logo on it.
