After a surprising moment (2018, after many years not having played a dcc in a portable)
Today I have compared the DCC 130, DCC 175, AudioQuest Dragon Fly (USB DAC) and my Iphone.
Test headphones a Denon over- & inear.
My personal rating (100=max) is as following:
- DCC 130 (88)
- DCC 175 (85)
- USB DAC (80)
- Iphone (65)
If you or someone has any detail question, let me know.
