My advice is to try it out for a couple of weeks with your Rogue. If after that you feel the Rogue is lacking something, then you can always upgrade. You can then look for a phono stage that addresses your current phono stages weaknesses. This will also allow you get a good feel for the differences between your existing Rogue phono stage and a potential phono stage, as you will probably have both in your system for a bit before you sell the one that you like the least. (And, if you buy used equipment, you can typically try out said equipment for a couple of weeks for only the cost of shipping, as you should be able to resell it for about the same cost, or sometimes slightly more if you are a shrewd buyer!)
My 2 cents worth anyway. (This is my standard method of upgrading components in my system).
