There are great inputs, thank you for all the information, especially AnakChan and Currawong.
Also special thanks to Anak for keeping the thread nice and clean. We get more positive and informative thread.
What I read so far is very tempting; excellent build quality, nice UI, fast working software, sound signature close to HM901 and it is not very far away from top dogs. Well for around 400 bucks, can you get any better? Don't forget that the device is also USB DAC/AMP too.
