Keep in mind none of the preamps you are inquiring about is really balanced design, despite having XLR outputs. Within the McIntosh line, to get a balanced design you have to go to the C500 (very expensive!), or just go to another manufacturer.
You might want to post the question over at the McIntosh forum in Audiokarma.
My two cents.
