I know that, that's why I emphasized "implementation".
Keep in mind D+M has obviously tons more technical resources than the smaller boutique like AV devices manufacturers. Take for instance, the PCM5102A has SINAD spec of only about 92 dB, yet several Marantz/Denon AVR such as the C40,50,even 70, AVR-X4800H manage >93 dB as measured by Amir, with peak performance at the 95 dB range. So how did they implement those key parts would be my question, did they buy hand picked one that meets their specs, they did promise in the marketing info in the early days, that the substituted DAC ICs will have the same performance as the renowned AK4458 right, and to a large degree, they kept their promise.
The PCM5102A dac datasheet does not mention "DSD", but it also does not say it is not capable (D+M also has not been clear about "native DSD playback", nor does it really matter? So it may be that depending on how it is implemented, it could do it, or D+M manage to use the DAC IC in conjunction with other parts, again, I don't know, you may ask other ASR members who has expertise in DAC IC implementation.
I have owned quite a few Marantz, Denon, now Anthem, if I want to play my DSD files, I would use my separates, or at least use my desktop DACs with the AVR/AVP's analog inputs, but then I am not keen on playing multichannel DSD at all anyway.
Regardless, it never stops me from wondering why D+M made their decision to go with the PCM5102A when there were so many alternatives at the time, including the popular ES9006, and even other TI DAC ICs.
