I've had the N6ii for about a month and I love it. Great UI, streams really well.
I'm mainly using it to drive my Campfire Solaris, which is a fantastic pairing with the N6ii. I also use it to drive my Utopia sometimes and it does a surprisingly good job! Highly recommend this after coming from an Oppo HA2-SE, which is a phenomenal DAC/amp, and a HiBy R6.
Cayin N6ii Master Quality Digital Audio Player -- A01 Audio Motherboard
This is an amazing DAP. Great battery life, smooth and quick UI, and the future motherboards make it very versatile. It does possess a warm sound signature but it is full of details and musicality!
Anyone would be happy with this purchase.
I have to say, I think my search for a DAP is over for now. I've owned quite a few DAPs around this price range and this is by far the best I've come across. The packaging is excellent, the build quality is top notch, and the software works really well. On the sound front, it is incredible. A few words to describe it... The N6ii has a reference tuning tilt but still so lush, engaging, and beautiful sounding, with an enormous amount of detail and slam. I'm rediscovering my music all over again. Well worth the purchase price.
