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.

OK, I will happily break my "last to say on the subject". I, and others, have offered suggestions to the poster. You have offered the poster nothing except to disparage those with whom you disagree (your usual tact). No counter suggestion for that person who seeks help - nothing. When you are challenged to do so, you throw out the TIRED "you are not on my level so you won't appreciate it anyway" crap. Fact is, you know little and have little to share. I could care less about CES or any of the manufacturers. You probably still try to attend those shows but get thrown out for being a loutish jerk (sound familiar?). I could also care less what any moderators think of my posts to you. You deserve anything you get, and if I get sanctioned, it is sanctions well spent.

Unlike you who has no idea of who I am or what is my experience, I have spoken with several who know YOU, Mr. Romy the Comrade in Boston. All affirm that you are as big of an ass in person as you are on these boards, have limited practical knowledge and experience of your own, and are basically a wannabe who doesn't have the brains or balls to be one. I dismiss you and your decidedly pseudo-intellect like a scratched LP.

Are you out of your mind? In the place when the barbarians like you delete each post that dose not support YOUR agenda you propose to find a valuable poster who value his/her own context. I am too familiar with your cheap, hypostatic tactics and too mach understand what stays behind your “diplomacy”

Regarding the rest, sweetheart, do not patronize me. I am very comfortable with who I am and put my understanding of audio, intellectual and life accomplishments against you and you-like ANYTIME. I know who and what hiding behind your implications and what agendas desperately trying to cash-out the chips of the “Romy-idiocy”.

Continue you cheap “play of public”.

You are too funny and highly pathetic there Romy. No one is "behind" what I say, as much as that fails to play into your neurotic and paranoid conspiracy theories. Pitiful. Get half a clue, then come back. On second thought, just stay away.

BTW, I have nothing to do with post deletion on this site or others though I know you use that claim as yet another ruse to deflect the real issue of your inadequacy and in attempts to engender some strange sympathy for your bogus "us against them", "I'm so oppressed" nonsense. Let's face it, you've been exposed, you're mad, and you can't fool me. Live with it.
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!

Signing off,
