I had a SP9-III, later a BAT vk5i, which was much better. Now using a Joule Electra LA-150, like that best of all. I think the more recent ARC preamps outperform the 9. They change models so frequently, that I have a tough time keeping them all straight.
A good friend uses a vk3i with his Mag 3.5s, BAT vk-500 ss amp, nice combo, too. Either the BAT or later ARCs would be good matches for you, IMHO.
