I also had the power supply mod done to my Art Audio Vinyl One by RHB Sound Dezign. I have not gotten the rest of the circuit modded by them yet, but am considering it.
I really loved the result. Wrote a raving review on Vinyl Asylum. Everybody should get this mod, in my not-very-humble opinion. For me, it was $300. He also replaced the stock wire in the unit, which he found to be sub-standard. My phono preamp really sings now. I forget if the new wire was additional cost or not, but it wasn't much.
