Has anyone tried IRF620 & IRF9620 for Balanced line Stage PREAMP. How does it sound compared to the 510 or 610?

I don't why, but I prefer the 510, but where I am, only the IRF510 are available and not the complimentary IRF9510.

Is it possible to use the IRF510 for the amp stage and others (eg IRF9620 and IRF620) for the power supply?.

Also since the IRF510 has max.Vds=100V, will the power supply need to be change say from +-60 rail to a much lower rail?
