Has anyone noticed the Marantz SA-10 SACD player? It is similar to the Direct Stream DAC’s where it upconverts everything to 32 bit with a sampling rate of 11.2896 for 44.1 multiples and 12.2888 for 48 multiples. Then, it downconverts it to one bit with a sampling rate not specified (as best as I can tell).
There is one part of the literature that is confusing to me. It talks about having filters that seem to be applicable only to PCM to me. Below is from their literature:
“These filters - one providing a slow roll-off and very short impulse response, the other offering the option of a medium roll-off with short pre-ringing and longer post-ringing - are essentially the same as those found in the Marantz SA-11 disc player and NA-11 network music player, but here they’re implemented at a much higher oversampling rate, thanks to that upconversion to DSD11.2.”
Do the Direct Stream DAC’s have similar filters? I thought there was only a low pass filter.
Did PS Audio get any patents for their Direct Stream DAC’s?
