I've been using a Pono player for a couple of months now and the sound quality is excellent. I purchased the silver balanced cable from Moon Audio for Shure SE846 earbuds I use 90% of the time and the upgrade bumped the sound quality up another notch. I use Grado PS1000 headphones the other 10% of the time and the Pono has no problem driving the larger phones. The sound quality is excellent with the Grados also. I no longer use my Apple iPod classic.
The Pono is not a streaming device btw.
