There is no end game till you lose passion in audio gear. Even if you acquire HE-1 or something, if you still passionate with audio gear then I'm more than sure you will purchase something else (power cable? conditioner audio grade? speaker? or perhaps HE-2 if that exist?)
Anyway,
Currently I'm burning in Hemp. Initial impression is great. I like the dense in vocality with hint of sweetness around it, without overpower or loosy decay of bass response. Treble remain safe for most of mainstream songs out there. Soundstage is still Grado in general, but surprise me a bit as flat pad not create congested soundstage as I expected. It's still wide enough to create space for good separation between instrument.
Oh man, the vocal on this headphone is truly superb! I think I like it better than RS1e for female voice.
The release of the Hemp followed a lot of testing of the current line up of Grado original pads and the designing the headphone to match the final choice which are the old style flats that are on the Hemp. Grado, yes, different yes. IMHO very refined performance at an extremely good price. As is the case with any of the limited edition models no one should forget that they will not be around forever as a option to purchase new. Once gone, they are gone. I know there were a lot of possible buyers for the GH2 as it was getting such good feedback and they are now essentially gone other than on the second hand market. The good thing is with any of these you would almost never lose out when you buy them. There will always be someone out there looking for what they missed. You should have no trouble selling and getting a major proportion of your money back if not all of it. I saw a GH1 listed recently at full retail price and I am pretty sure it will be sold in short order.
