Even though your response to Mr. Maher was douchy, my advice would be to get a good portable amp that you can use with your Shures. You can use a portable with your preamp and then take it with you when you are mobile. The HeadAmp AE-2 is a very good option at $349 new and less used. It has RCA inputs on the back and an mini jack on the front. Other portables have RCA inputs but I am not sure which ones. Also, you can simply use a good quality RCA-mini cable and use any of the variety of portable amps.
Either way, just DON'T ACT LIKE A DICK on this site and you will get along fine.
