Yes, that is correct. These are high-end consumer and professional
audio components.<br>
<br>
By the way, SACD is not anything special. It is just a bit stream
from a sigma-delta ADC modulator minus the FIR filter. In fact, the
original SACD spec was based on the 1986 vintage Analog Devices
AD1879 in a test mode that outputs the 1-bit stream from its
modulator. This was never intended to be used this way, so the SACD
spec audio actually has a tremendous amount of noise above 20kHz
which was intended to be cut by the digital filter. It was created
by Sony because their CD patent had run out. DVD-Audio was always
the better format.<br>
