Have never heard the Liberty (and am extremely happy with the SimAudio Moon 5.3 with external power supply I just replaced by P75 with), but based on reviews and specs it does certainly seem worth taking a close look at. I have no problem with a manufacturer suggesting you look at his product. He makes no claims for it in this forum, and identifies himself as the manufacturer (if he hadn't done that it would be a problem in my book).
Anyway, loads of great phono stages out there. Most important is to try them in your system to see what works best in your particular rig.
