Which ARC Phono Preamp?

Hi Folks:

I'm looking for advice on which ARC phono pre I should purchase to complement my system. I'm considering the PH-7, Reference Phono and a GNSC modified PH-5. Current analogue rig is a VPI Scout/JMW-9/Dyna 20XM. The rest is an ARC LS-26 feeding an ARC 150.2 powering Daedalus DA-1.1's. Anyone who has experience with one or more of these is welcome to jump in. I'm looking to buy my "last" phono preamp and the next system upgrade will be a new table/arm/cartridge so don't hang too much on the current vinyl set up.

Thanks for your help.
