I think you should tell us a bit more about the installation, in 
particular regarding your requirements and budget. I'm quite confused at 
this stage - on the one hand, we're talking about dedicated ADAT 
converter boxes and you seem to be worried about noise (this is 2011 - 
even cheap digital is pretty darn good...), on the other hand you want 
to keep the costs low.
