9v DC PSU Audio Grade

Hello all,

I am in the market for a 9v AC/DC power supply for use with my headphone amp. I would prefer the cost to be under $10 but I will go up to $15 if needed. If someone could find a circuit or diy guide that would also work.

I recently got a 9v ac/dc psu from China and it introduced a very high sound that overpowered the sound of the music, signifying that it was not built with audio in mind.

Do you have and suggestions?

I guess I did not look long enough before posting. I am thinking about this.

Anyone have some suggestions?
