I have the VTF3 mk3 and a STF2, so mine are one step above and below the one you are considering. These things are terrific for music and movies, although I just use them for music. I was so impressed with the STF2 that I wanted to see what a much more powerful HSU would sound like, so I bought the VTF3, and, wow, jesus!
If you go with the VTF2 you will love it, seriously.
