I agree with what bcowen was getting at. A real outboard supply would probably yield an audible improvement just because it would be a superior power supply to any wall wart. You could use high quality, low noise diodes, more capacitance, CLC or CRC filtering, and yes, also a larger transformer (probably the least needed part of what you might want to build or buy, but also worth doing). I'd say, build it from components you select; don't buy a done unit unless you know exactly what is in it and why it is superior to your wall wart.
