suggestions for step up transformer for benz ruby2

Hi everybody,
after doing a good deal of reading I understand what electrical characteristics a step up transformer will be required to have in order to mate well with my ruby 2, but I was wondering if any body had anything usefull to recommend. I recently sent my counterpoint sa-5000 in to alta vista for a rebuild of the line and phono stages and am having the solid state mc step up removed. When the unit is returned I would really like to have everything in order so that I can do some listening. From what I have read, the benz micro ruby 2 has simillar electrical characteristics as the denon dl-103. Has anyone done any comparisons of step ups with either of these two carts?
