Is it correct to assume that "if there is no sound card, and if we

Or rephrasing it this way - What would be the passband of the signal
output from the QSD ?
These are somewhat independent issues. It is certainly true that the
higher the sampling rate (~ADC freq) the more of the band you could
see, potentially. However the output bandwidth of the QSD really
depends on the specific components in the QSD. What it is in the case
of the SoftRock I do not know.
One of the clever features of the QSD is that the effective Q of the
sampling filters is constant over the tuning range of the QSD. Not
something that affects the SR40 much, of course :-)
