Doge 8 or YS A2 or Jungson J2?

Looking for a line stage preamp with remote volume and source selection, and these look pretty good for the money. I can't find much by way of reviews through Google, so am hoping some of you have impressions of these units, or just of the manufacture or sound quality of these brands. The only recommendation I have received so far is for the Doge. I need a 230V version and each of these can do that.

Thanks for any insights.
