Advice on what preamp to select.

Hello
I picked up two Adcom GFA565 Power Amps recently and would like to get a newer preamp to go with these.  Currently have a Crown IC150.  Have found a Audio Research SP-9 MKII for about $1100 but am considering also the following: Macintosh C series in the range of the 34V or newer, or purchasing a Mac MX series preamp.
The MX 130 looks to have decent reviews just being used as a solid preamp for stereo use and has a phono section which I need.  I know this is a question with no best answer but anyone have experience that they are willing to share?
Thanks
Kent
