Oddioo,
Since you have the "n" version on its way, enjoy it in your system for a while. Later on, if you feel the urge to go balanced with the bigger transformers in the nB version( remember that you'll need balanced interconnects) you can always upgrade at any time. Like I said, I'm perfectly content with the original 2.0n version. Also, if you hadn't done it yet, start at the beginning of this thread and read through its entirety. There're a lot of posts in there commenting on the different versions along with comparisons to other preamps. Hey, if the preamp doesn't work for your system you can always return it and give the Ultraverve a try. I'm not familiar with your Rogue monoblocks or your Dali speakers, so you might ask Joseph or Victor how they feel about the preamp's compatibility. Have fun.
