came by chance about this facts/post in this very interesting forum->http://www.diyaudio.com/forums/pc-based/302687-es9018k2m-es9028q2m-9038q2m-dsd-i2s-dac-hats-raspberry-pi-17.html
„iancanada“ posted:“..ES9018 and ES9028 need the small DoP daughter board (which can be plugged in the IsolatorPi) to convert the DoP stream into DSD. However ES9038Q2M has a built in DoP decoder, so, for ES9038Q2M, the DoP daughter board is not a must.“,
+“ESS9018/28/38 has internal 32bit digital volume control. Much better than any 24bit digital volume control, but still not as good as the analog one on my PASS XP-10. However according to my listening experience, the difference is not that huge.“..
by that his „ES9038Q2M DAC HAT“ looks very fine, neat and „sophisticated“ 😉 ; mail him..😉
