My reaction to the HF2 was similar to Katuns with the RS1 I think. The bottom line for me was plunking down $450 for a pair of headphones was a lot of money. Money I was willing to pay to satisfy my curiosity but enough that it was keeping me from fairly evaluating the HF2. That and the HF2 really bloomed after it burned in. I cant imagine ever parting with them now.
I'm glad Katun is taking the Bilavideo challenge. A woodied SR60 is a real treat, I love mine. The Bilagrado Kool Aid is very addictive though, I'm planning on modding a 225 next. I had read on one of these Grado threads a while back that any particular Grado model was a simple matter of reverse engineeering. The higher end Grado's had better drivers, better cabling, wood in place of plastic, etc.
So it sort of stands to reason if you start replacing some of the pieces Grado tore away, you can end up back where they started, or somewhere in the approximate vicinity, and for a lot less money. Tonally a woodied 60 is fuller, richer, warmer, more organic. The difference between a real flower and a plastic one in my estimation.
