Even if you wanted to replace it, the Alps Blue in the Auralic Taurus is soldered to the main PCB, and it's a bear to desolder this part. (If you did get it removed, there is enough space to replace it with a small imitation Dact-style pot though.)
If you still have hum when you touch the pot after tightening the nut against the chassis, I'd suggest sending it back to Auralic to repair. I know I'm in the minority here, but I had one bad experience in the past with a genuine Alps Blue pot that I could never get properly grounded. Probably from a bad batch, but if that's also the case with your unit Auralic would probably need to replace it.
