The ZD is three times the price of the Ear+ and there are many other choices in between. A lot of tube amp choices out there will drive Grados well once you go over the $500 price point .... and there are always some excellent deals on used amps. If you have the cash the ZD is an excellent amp. But, so is the Ear+ if you are only going to be using Grados.
