Now this must be a stupid question but i gotta ask, on my Sony AMp when you turn the thing up the number goes down. I think it says dbs or somthing, is that decibles (sp). IF so why does this decrease the the noise increases? Also i have some AG Micro Ti speakers (sub on its way ) which are very quiet, the output shows 10 dbs does this seem high or is it becasue the subs missing or because they are new ?! cheers!
