I just bought my new CA 540A amp about 3-4 weeks ago, And am really enjoying it. But to me it sounds alittle diffrent, There seems to be alittle more bass coming thought, And the midrange has become softer. Now is there any truth in this?. Do amps sound diffrent after some run in time?. > Thanks > Luke

Here we go again. My favourite subject ... Yawn. Still ...
Its rubbish. Amplifiers, CD players and cables DONT require any 'burning in/bedding in' or whatever you want to call it unlike loudspeakers. They do not improve after an initial warm up to stabilize circuits and in case of cables its usually a few sharks that want to cash in by supplying the things 'pre-burnt-in' for a little extra like thirty quid or so, nice.
Its not unusual in case of amplifiers for output transistor distortion to actually rise when warming up. Now I sometimes find that I like a bit of distortion but that manifest itself over a short period of time not days/weeks or years (Hello again darren, chairman of clearaudio).
What you are hearing is your hearing becoming accustomed to a change in your system. Psycho-acoustics. Thats all. Enjoy
