The question is, does the slight hum have any practical effect. While the best transformers may not hum having one that makes the slight noise yours does does not mean that it is a bad transformer or that performance is necessarily bad. There are components where everything has been selected with cost no object and they are very expensive. Good designers select components that will do a good job at a reasonable price, if you are happy with the performance otherwise don't worry.
