Finally received my NFB11.
Its the latest version, cooling grills on top and everything.
It arrived very well packed (like a tank actually) with an USB cable, power cable and caps for the RCA outputs.
I did as instructed here on the forums by Kingwa and started the unit after the pc complete boot up.
Installation gave me a 1607 error (something with installshield wizard) so i installed only the drivers per se (without the Via audio panel).
Opened Aimp, select Wasapi 32bit 384kbit and VOILA !!
The sound is so much richer and detailed than my receiver, i could discerne Madonna tapping her neck thru the music.
The mids, highs and lows are all there. Representation is very neutral and detailed.
I could hear someone laughing during the Creedence Ramble Tamble that i never heard before.
So far im really impressed by the 30min run (lunch time haha) i had with it.
This night i will test more.
Overall im much satisfied (so far), Audio GD personnel kept emailing me about the status of the shipping and the unit after i received it.
Thanks guys.
