Good advice. But I have a real hard time not drawing conclusions from listening to a new piece of equipment… and can be disappointed… I know I shouldn’t draw conclusions… but I do. So, it can be safer to wait… but you have to put a signal through it while breaking in.
More than once I have been so anxious to hear my new piece of equipment and thought, “it sounds OK”… not what I was hopping for… depressing. Then after 150 hours, hearing it greatly improve… and really being upset with myself… I know better than this… once again forgetting how important breakin is.
