Lyra Helicon cartridge with what pre-amp?

if you have a line preamp you can use Audio REsearch PH3.
if you want something of higher performance than try Pass X ono or Audio Synthesis that you can use with passive preamp.

BAT vkp-10 up to 73db gain, can load cartride with the flick of a switch (about a zillion screws on the outside case though)used on audiogon between $2100 to $2300 + resale is outstanding.Oh did I mention the sound, need I say more. David
