Since about 10 years I own a PS Audio GCPH which does a good job between a vdH Frog and a YBA 2 preamp. Very precise but smooth, gives a wide stage and exact timing. You can find this unit in good condition for about $ 600.-, maybe less in the U.S.. It gives possibility to adjust the gain and the resistance so you are prepared for pickup changes in the future. I stayed with the GCPH since a reasonable upgrade would cost thousands of bucks.
