Good thread. It reinforces the point that one does not neccesarily need expensive kit to enjoy music. I have not heard the SR60, but owned the SR80, but really the only reason why I got rid of it was its comfort... I cant stand to wear them, but apart from that, I would say it did have good groove.
To me, a groovalizer is simply a headphone that makes you forget about listening to hifi and enjoying the music - regardless of its technical merits. This is why I still have my Beyers.
