In Reply to: My unanswered question on these kinds of DAC remain... posted by DAVID on November 12, 2016 at 10:06:14:
The old dac chips can handle quite high sample rates. For instance, the AD1865 and PCM63 can do 8 x 44.1kHz and the TDA1541a can do 4x or 8x depending on implementation. In their original cd players of the 80s, there were oversampling chips built in so that the 44.1kHz data was oversampled before it got to the dac chip.
If the dac is set up for NOS and the input/interface device allows, a dac with one of the old dac chips can handle high resolution, i.e. max. of 8x 44.1kHz = 352.8kHz or 8 x 48kHz = 384kHz.
The input/interface device (USB to I2S, USB to SPDIF, etc) is usually the limiting factor and that is usually governed by the conversion chip (i.e. XMOS, etc) and the speed of the clocks installed.
