now that the DUST has settled, I re-bought a Grado HF-1 used and heard it for the first time since 2006. HF-1 was the first headphone I loved, and now I remember why.
Between HF-2 and HF-1, I must say I prefer the 1.
The plastic + wood combo is better for me than wood + aluminum. that's superficial tho.
HF1, it is smooth and fast for rock, always enjoyable ... HF-2 had better individual qualities like timbre and separation, had a bigger sound and was a more serious can, great for jazz. However I already have some serious headphones so I sold it pretty quick.
Buying used the HF-2 is gonna be pretty close in price to the 1, only by $100-$150 usually. While it is technically better, I prefer the 1. Why?
Because HF-1 I can use portably, walking on the street or jogging. I chose it over the RS-1 for that reason. It maintains some of the qualities of the top RS grado cans with the casualness of the cheaper models. Wearing it you are wearing a 'secret' that no one knows will sound that good. it is a deceptive bugger.
so I love my HF-1, it is the best Grado for me, has everything I like in a Grado. it is not 'audiophile' as the other top grados.but it has its own vibe that you will fall in love with. No one talks about it because it's long out of P and HF-2 its big brother has come out. but if you are looking for a special can, a 'joe pesci' who packs a mean and smart punch, I recommend you snatch it up if it comes used in the forums
