I am a big believer that the power supply can be extremely important to quality musical component and always key in an amplifirer.
Some lower power equipment can have a quality on-board power supply.
I was just talking to a friend today and he mentioned Dave as an example where many believe the on-board power supply is excellent while others disagree.
I have a Dave with M Scaler and have really worked to bring the rest of the components in my digital stream up to it's level.
Now you've got me wondering if I should jump on the power supply.
