Have a very nice Burson Composer dac. Since I got out of headphones I don't listen to music as often. Was very happy with it as a dac and preamp. Very clean and detailed sound. Voices and guitars where extra nice on this. I do not have the box but have the box the extras came in but will be boxed real well with insurance. Has the stock power supply and as far as I know stock op amps. Not sure if these came with the XLR adapters but this does not come with them. I got a good deal on this and want to pass it on for what I have into it. All fees are on me and my price is with shipping.
