A new Preamp needed.......

I have an Aragon 8008 mk2 amp and an Aragon 28k m2 preamp along with a Cary CDP 1 cd player. I really would like to run my system balanced as both the amp and cd player are balanced and sound better that way. Th problem is my preamp is single ended. I don't want to spend too much money on this. I am looking at a Marsh 2000b or a Wyred for Sound STP SE. Any thoughts on these two and how they would fit into what I have? I am using PAD cables as well. Thank you.
