Here are some measurements of my Kenwood DP-7090 - this player has no less than 4 PCM1702 DACs per channel.

Just like the dual DAC Sony I posted earlier, it doesn't measure as good as I had expected.

My test setup: Asus Xonar STX sound card with a self built buffer / gain box in front of that. Host PC is an Intel i7 running Windows 10 with 32G RAM and SSD - no mechanical disks or CDROM drive present.
I also use an Altor Audio Olivine-2 ADC, however the Asus Xonar was used these measurements.
Sound card input was set to 24bit/96kHz
REW was configured as per the recommendations in the post from @NTTY

Something about ultrasonic band attenuation?
19k / 20k tone or better triplet tone and check out of band attenuaton would be very interesting.
Cheers,
Luca
