at 44.1kHz. This
is the distortion spectrum of the Rapture card when reproducing a 1kHz
full-scale sine wave (1kHz suppressed) from a 44.1kHz source (like a
CD). Notice that the spectrum looks like what you might expect to find
from a low-feedback analog circuit -- evidence of the Rapture's natural,
unfatiguing high-resolution sonic quality. Upsamplers look nothing
like this, generating all sorts of disconcerting inharmonically-related
spurious sub and supersonic sidebands and tones. (Image courtesy BHK

| Rapture
at 48kHz. This
is the distortion spectrum of the Rapture card when reproducing a 1kHz
full-scale sine wave (1kHz suppressed) from a 48kHz source (like a DAT).
Notice that the spectrum looks essentially the same as the 44.1kHz one.

| Rapture
at 96kHz. This
is the distortion spectrum of the Rapture card when reproducing a 1kHz
full-scale sine wave (1kHz suppressed) from a 96kHz source (like an
audio-DVD). Again, the spectrum looks essentially the same as the 44.1kHz
one, indicating that the Rapture has NO PROBLEM generating beautiful,
musical audio from even fast sources. (Image courtesy BHK Labs.) |
