Ok, ok. I give, I did get to listen to an A&K DAP once. I'd dropped by ALO HQ in Portland to meet Ken and pick up an Rx to try out. Turns out Ken wanted me to audition the Campfire Audio IEM (which btw are awesome!). I didn't know that was coming, so I hadn't brought a source. Ken pulled out what was obviously an A&K DAP. I asked if it was AK240. Nope. AK380. AK380 + Campfire Audio Jupiter almost blew my mind! However, since I didn't bring one of my own DAPs for comparison, I don't know how much of it was AK380, Jupiter, or both and really only spent about an hour with it, so I don't really include when talking about DAPs I've auditioned.
Not sure if the magic circuitry is in Cozoy's cable or in Astrapi. I sent my Aegis (which also gets by without CCK) to a headfi buddy in Canada, so I couldn't test that out. The thought has crossed my mind but slipped right out when I couldn't test it, so I'm glad you brought it up.
