I wonder how the NFB-2/3 compare with the Meier Audio STAGEDAC, which uses WM8741s as well.

Did some USB vs. Coaxial listening again tonight. The hum returns while connected through USB although the volume of the hum is much lower than that of the first time when I hooked up the DAC with my laptop. Since my speakers (Focal Chorus 714V) have a sensitivity of 91dB, they're quite revealing. On the other hand, the coaxial input is dead quiet. The USB implementation in NFB-3 (or Tenor chip in general) is a disappointment; I guess it's inferior to asynchronous applications.
Kingwa suggested the hum is due to the ground loop problem and it seemed it's the power supply to my laptop (Using the battery eliminates the noise). However, the plug of the PSU is three prong; if I use a three to two prong adapter, it may fry the laptop's battery.
Why? Does it say that in the instructions? I've never heard such a thing before. Notebooks (they aren't called laptops now due to the heat they put out causing burns) are designed to be used internationally, where many countries, for the most part, only have 2-prong sockets.
I read somewhere on the Net
I read somewhere on the Net that battery could be in danger if the plug is not grounded. The recent notebooks I bought all come with a three prong plug (a pain for interntional traveling). There must be a reason for doing so.
My Sony VAIO has a 2 prong plug and hasn't blown up yet!
In other news I think I am going to order the NFB-3. Do you all think it'll be a real upgrade over my Zero DAC?
NFB-2/3 of course.
