Please, complete this home studio!

Hi,



My home studio today is as follows:



Apogee Duet for Mac

AT4050

Sm57

Yamaha HS7



I would like to add an external single or dual channel preamp up to 1K max and a single or pair of small diaphragm condensers up to U$500



Been thinking of the NT5's and UA610 Solo.



What would you suggest?



Thanks,



Rodrigo Tavares.
