Chuck, you can use a linear power supply (LPS) and get rid of the wall-wart. A LPS uses a toroidal or R-Core transformer instead of the switched mode PS found in the cheap and noisy W-W. The result will be a significant improvement in sonics; better dynamics and detail, larger soundstage, lower noise floor.
You just need to know the voltage and amperes needed to run your TT.
