Amperior and HD25-1 use the same driver. Both share the same spec, save the impedance. The "hip" version is easier to drive than the "pro" version, but to say one driver is inferior than the other is a stretch. It all comes down to marketing. It is like saying that the ER4S driver is better than the ER4P driver, when both use the same driver, but are tuned differently, with the ER4P being easier to drive and can be converted to an ER4S with a in-line impedance. This is why I laugh at some of these nonsense reviews on the amperior made by hd25 purists.
