Best preamp for Low output Grado Cartridge

Any other suggestion/opinion? :-(

PS Audio GCPH with Level 1 MODs (Underwood). Now I have not made up my mind on this phono stage although I have had it 7 or 8 months, because I could not get acceptable performance while playing records. Regardless of cartridge (mm, mc, mi), sound was too thin and mechanical. Well Saturday I put my Grado Staement Series Master back on. When I had tried it before, it had many of the characteristics I wrote before, plus also dull and boring. This time it sounds excellent with very smooth lifelike mids and fairly extended bass. I did select the highest gain setting this time (65db?). Now, the turntable sounds better than the CD player.
