Hi gain phono preamp reccomendations

I need a MM phono preamp with lots of gain. I figure based on all the other parts of my system (cartridge output, the fact I use a passive linestage) that I will need a good 50db gain. I also want it to have a low impedence output under 100 ohms. I will be using a fairly long output interconnect as well. (10 feet) The Grado is almost enough gain and low impedence out but I think I would like something a bit nicer and with more gain. I do prefer tubes as well. The Hagarman Coronet is a little light on gain and has too high an output impedence. I can't afford a CJ Premier which would be nice as well. So if anyone knows any pre that fits these needs let me know. I have done a lot of searching and keep coming up empty. Thanks in advance.
