You don't have any Clearaudio carts on your chart, so I'll offer up mine. My Clearaudio Maestro Wood v1 MM cartridge sounds excellent on the original Phono1 with stock 47k, 150pF loading. (I assume original Phono1 had the same capacitance as the mk2's 150pF?) Plenty of treble clarity and detail. Thanks for making a great product.
