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.

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.
Shame on you. And learn some English.

So how do YOU know my advice was bad. At least I have SOMETHING to offer. All you have, like Romy, is unsupported criticism. Talk about being all talk.
I have the Mitchell Cotter Mk2 Step-up Transformer, and the factory instruction sheet to adjust the loading via soldered jumpers. Is this something that is considered a "serious" step-up device? I have lived with it for some time now. Am I getting close to qualifying as someone who knows about, and lives with, a serious step-up device? My fragile, audiophile ego is at stake here.
Tom (Twl) I know you're being sarcastic and I know you are not referring to me. For the other two "experts" I will say that Tom's reputation for having REAL knowledge and experience in the field of audio, AND a willingness to share it is beyond reproach. They (he) will never answer your question because they (he) has no real knowledge. To mask that fact, they (he) will only offer lame excuses as to why they won't (probably something to do with being superior and not being bothered to stoop to your level).

And let me ask you this Mr. Kevinkwann. How do you KNOW advice given here is wrong? You say "more listen". Have you HEARD the K & K? Have you HEARD the Bent? Have you HEARD the Cotter? Have you HEARD the Granite. I have, except for the Cotter, and many others. If you haven't, you have no business telling others that their advice is bad. If you HAVE heard them, WHY is suggesting them bad advice? WHAT would YOU suggest instead. Waiting for a constructive reply which I doubt will come.

Oh, surprise. In viewing your SIX other posts, they ALL have the same character as Romy's many. Same sarcastic. same critical with no support or alternatives. Same idiocy. Are you guys clones, both just as vile as the other, or maybe the same person?
Yes, David, you got me right. Just being sarcastic to the comments from the peanut gallery. I was also targeted as being "not qualified" to give decent advice. Interestingly enough, apparently so was Mr. Hagerman(Hagtech), who makes a very nice phono stage that is quite highly regarded by many. I guess none of us are up to Romy's high standards. :^)
