Before you do, I suggest that you carefully check to see if it conforms to 
AES48 (the "pin 1 problem" Standard. Most stuff like that does not, and any 
box with a pin 1 problem is likely to suffer from hum, buzz, and RFI. Look at 
the input and output jacks carefully -- if they are screwed down to the 
chassis, they don't have a pin 1 problem. If they poke through the chassis on 
holes that are larger than the jacks or are insulated from the chassis, they 
DO have a pin 1 problem. 

The most dependable mfr in that regard is Rane, and they have a very nice 
headphone amp.
