Linn Linto vs Audio Research PH3

Has anyone had the opportunity to compare the Linn Linto phono preamp versus the Audio Research PH3 phono preamp (in either the standard or SE configurationn) using the Linn LP12 turntable?

I have an AR PH3 SE. I am pleased overall with the sound but it doesn't have as much gain as I'd like to drive my Linn Arkiv cartridge. In order to get to reasonable volume levels in my small listening room, I have to set my AR LS 25 preamp to the highest input gain setting (18 db) and turn the volume all the way up to the 3 o'clock position. My other input sources work just fine with the 12 db setting and the volume at the 12 o'clock setting or less. Amplication is via an AR VT 100 and speakers are Magnepan 1.6's.
