Not sure you'll find it. But it doesn't really matter. Measuremnets are what you need. You could have the best chip in the world and still mess up the design to get really poor results.

Fortunately for you, I've found this:


With some measurements about 2/3 the way down the page. It looks pretty good.
 
The AVR-X5200W uses two PCM1690 DACs for Zone 1 and two PCM5100 DACs for Zone 2.

These provide more than adequate D->A conversion, so there's no point in buying an external DAC :)

thank you for teplying. Could you be able to also find about the dac in Denon AVR-X4200W? Again i found nothing online.
 
Simply search the service manual for the DAC model name using Ctrl+F and it'll show you where.
Thanks for replying. Another question - i use left right rca to lightning cable to stream music from my iphone. The cable i have has small dac in the adapter. Also there is a dac in my iphone and receiver has its own dac. So when i stream music, which dac is being used?

Normally:
Lightning dongle DAC --> Receiver ADC --> Receiver DAC
(I am quite positive that your Lightning to RCA cable has to contain a USB codec/DAC.)

"Pure Direct" mode may bypass the receiver's internal conversion, consult the service manual for any hints in that regard.

With the avr if you're using audio processing in the avr it will do an adc for that (along with another dac conversion), if you use pure direct it would bypass the processing in the avr. If using rca output from your dac via the dac/cable, you're using the dac in it. If you wanted to export the files from your phone digitally you could use airplay direct to the avr without a cable.

I use direct mode not pure direct. So avr still using its dac.

the reason i asked is because i want to use only avr’s dac. How can i achieve that?

In Denon avrs pure direct's only difference is it turns off the avr's panel video/analog circuit. Both direct/pure direct in Denons will bypass processing. Connect the phone digitally via appropriate digital cable (don't know options on iphone cabling for that) or just go wireless direct to the avr via airplay.

Isn't it more a lightning to hdmi cable? Likewise, lightning to coax? (i.e. follow the direction of the signal). Both sound like they'd be digital for use of the dac in the avr. OTOH not familiar with apple phone outputs so not sure what the dac is doing (or where the analog audio is "going"). On my android phone I don't bother with cables when connecting to audio gear, if I'm even using a phone, just wifi.
