I think the fact that Creek is selling cheap wall warts for use with a phono stage (in particular) is inexcusable. These amps have a big job to do amplifying a tiny signal, and the potential for injection of noise and RFI into the system is rampant. It's unbelievable that Creek would supply the OBH-1 with *anything* audio related, as it's become abundantly clear that it's a complete piece of crap. I wouldn't use it to power an electric toothbrush, let alone a phono stage.
P.S. to everyone -- I added an addendum to the original post (top of thread), which imho is worth noting.
