I agree. Ideal would be to send the Devialet the Expert internal native bit/sample rate (so that no conversions are required) but I'm afraid the digital inputs are really limited to 24/192 or DoP (in our case DSD64 over PCM) and won't support higher sampling rates even if the FPGA/DSP internal native bit/sample rate is 40/384.
Even if 40/384 would work you'd need a very powerful computer for it but I don't think there are interfaces that support a bit/sample rate that high. AES/EBU and S/PDIF are limited to 24/192 and even USB Audio 2.0 is limited to 32/384.
PS. I found this by Mauidan (it gives an additional hint but I still think this isn't the full story):

Quote:I asked Devialet how it handles the "Devialet internal PCM 40 bit/384kHz processing bitrate," If the PCM 1792 DAC chip in the Experts are limited to 24bit/192khz?
Answer:
In all our Expert units, we use one 1792 chip per channelallowing a doubled bandwidth compared to stereo designs employing only onechip.
