After swapping cans with Chris in the past, I decided to buy his AD2000s when he put them up for sale. We met in person, bought some CDs at the Tower going out of business sale, and had a smooth and very pleasant transaction. The cans are in perfect shape with all the trappings and original packaging. I highly recommend Coolshot as a quality Head-Fier and trustworthy seller.
I bought from Coolshot a Diyeden Great March modified by Pacific Valve. Shipping was fast (priority mail that I was not expecting) and top packaging , wrapped in the original box, itself in an other package with those pink styrofoam thingies (sorry, do not know the name of those).
A great deal, good communication and a very understanding person.
Highly recommended +++
