Boa2 - Please let us know what you think of the unit when you get it.
I'm on the fence about ordering one. First, it's silly expensive, and second, its operating principles don't make sense.
Whest claims that the DAP acts to realign frequencies above 35khz and has no effect on frequencies below this point. The problem I have is that no properly designed CD player, whether oversampled, upsampled, or non-oversampled (1FS) has any output above 22.05 khz (half the Nyquist sampling frequency of 44.1 khz). One of the major jobs of the reconstruction filters (digital and analog) in the player/DAC is to block everything above this point.
SACD has output beyond 35khz, but much of this is quantization noise relocated from the audio range to this region by the player's noise shaping circuits. It has little correlation to the music.
SO what is this box really doing? Since my DAC has no output above 22.05 khz on Redbook, then what is this box acting on?
Let us know your impressions.
