transistor pre with the sound of tubes


Not sure i am mature enough for a tube preamp, so my quest would be for a transistor pre with a hint of tube sound.
What would be your suggestions? 
Btw, needs to be balanced as my active speakers only accept balanced.

I was thinking of Classe and Gamut. But perhaps i should consider your suggestions!
Ayre's preamps are very good.  The K5xeMP is a steal used and has a warmer sound than some tube units I have heard.

I wasn't aware there's an age restriction warning on the box?

You want a tube preamp, GET ONE
