No offense Ezmeralda, but Doug Self can listen to his system how he wants. Regardless of who has how many books published, his thoughts and opinions on the subject are simply that, his thoughts and opinions. Personally, i think that he is FAR more hung up on measuring things than to listening to them. Personally, i do not know how well his designs work, as i've never used, heard or even seen one of them.
I suggest that one try leaving the system powered up and listening as you normally would. One should obviously take precautions when leaving the system unattended, but one should do that anyway. If you don't notice any difference after a few days ( at least 72 hours of continuous power ), then go back to powering it up and down as needed. Nothing lost except for a small amount of electricity and a few pennies.
My findings are that very richly biased AB amps and those that truly are Class A sound best after 2 - 3 days of continuous power. Amps of low bias AB design or models using some type of switching supply typically sound as good as they are going to get after a half an hour or so.
As far as tubes go, i would put preamps into standby mode and leave them on. Tube power amps should be powered down and fired up as needed unless the system is used most of the time.
Obviously, these are only suggestions based on past experience, just like those of Mr Self's. Sean
