Hello Ken.You have a wonderful system!The wright line stage is the wpl 12a,the wpl-20 is basically the same line stage coupled with a phono stage.A good friend uses an identical system as yours with[shearwater hotrods].He aquired the wright preamp wpl-20 after using an audible Illusions 3a[no slouch] for a few years.Although his wright was acquired more for vinyl playback, it dramatically improved his system in every way.I have personally auditioned it in my own system and can attest to its magical qualities.Needless to say,I am now a big "fan" of George Wrights products and would recommend their equipment without reservation.Cheers David.
