Ok, so bought the audio gd NFB-2 in the hope that I would get an audible improvement in the sound from my Squeezebox Touch (SB). I decided to run a blind ABX test with a friend to see if we could pick the difference in sound.
The setup was: Squeezebox coax digital out into audio gd NFB-2, analogue outs to an attenuator and then to an ABX unit. The attenuator was necessary since the output levels on the gd are higher. The analogue outs from the SB were also fed into the ABX unit. The ABX unit had a function to randomize what the next source was for X. This output from the ABX unit was fed into a yamaha rs-700 and then into a pair of B&W 685s.
With the levels matched, before we even started in earnest, just switching beetween the sources demonstrated that it was obvious that there was no perceptible difference. We continued with the ABX test and in the first 10 "guesses" I managed to get.... 5 correct... Hmmm...
The bottom line was that we could not distinguish the difference between the two, let alone decide which one was better.
