Seperate phono stage v.s. step up transformer


Fellow analog lovers help me with this dilemma. I have a Teres 265 turntable with a Graham 2.2 arm and a Lyra Helikon cartirdge. I just purchased a new preamp that has a terrific phono stage but, its' sensitivity is 2mV @47Kohms and the Lyra cartridge is only 0.22mV.
So I have 3 choices, get a new cartridge, get a seperate phono stage, or a step up transformer.
What would those of you with more experience in these things do? If it is change cartridge, which one? If seperate phono stage, which one? If a step up transformer can be used without sacrificing any detail, dynamics, etc. which one?
Thanks ahead of time to any of you that answer these questions.

Sure, and who put you in position to quantify me? Were it you yourself or was it your strong NEED do not admit the fact of your OWN exposition?

I was pronounced by many of your “friends” and the "mental colleagues", even presented with the evidences, that Romy is a high ranking member of mafia, the associate of Ocama bin Baden, hidden audio publisher, secret manufacturer of audio equipment, sexual offender, a 13 year old person, IQ-clanged person, well masqueraded audio dealer and of course the pinnacle of the audio intellectualism: a mad person...

Well, I admit that I am qualified to be all of them, even more: I am a person who read your cretinism, look at you and say: what a feeble idiot you are!

Yep, the person who is in his search for a Best Bolero and whose brain is just a pile of the primitive audiophoolic dogmas and fears have the dreams to be my challenger! Actually even your attention to “Romy the Cat” insults me.

Oooo, you have brains enough to do a forum search. I'm shocked. Why waste any time on the likes of you - inferior being as you clearly are in terms of intellect, morality, and even muscial taste. When and if you can ever drag yourself up to a point which allows you to engage in discourse at a level equivalent to a third-grader, let me know and I MIGHT have some fun with you. Otherwise, you remain an insufferable and pathetic loser and I'm afraid your low-grade intellect will rub off on the board. You're exposed Romy and you can't take it. Your very being insults me. You can have the last word, though, It will no doubt be as nintelligible as all of your posts.
4yanx: Romy bore you? You bore everbody else! Maybe spend less time talk and more time listen then maybe you learn. You give bad advice about subject know nothing about then get upset when Romy point it out? Shame on you.
