K3 is a big no-no as some of you have mentioned. When you nail into the hardwood and it goes down on the K3, it literally goes right through it so the new hardwood would not settle properly. The floor will have humps and dips over time.
I have had people ask me to do it this way, because they were too cheap to fork out a bit more to get a new subfloor installed. Do it right the first time is what I always tell people, but most of them don't listen.
