Dear @Viridian: Neither the Van den Hul Grasshopper II.
@dcaudio , do it a favor and stay away of transimpedance/current phono stage designs instead your choice most be for voltage phono stage designs. SUT always is an inferior choice against an active high gain pgono stage design.
You can look for the PS Audio Stellar that outperforms any MM/SUT combination (tube or SS ) .

and Fremer compared against the CH P1/X1, Ypsilon and others ( with prices over 20-30 times the humble PS Audio price tag. ) using top SAT tonearm and Caliburn TT and cartridges of the caliber of Lyra Atlas SL.
Obviously is interesting to read the M.Fremer review including the real time measurements page.
Regards and enjoy the MUSIC NOT DISTORTIONS,
