The QP2R delivers sound that is pure mastery. I have really enjoyed the QP2R and while the Opus#2 has been a loyal mate I feel that I have certainly moved on with the QP2R. It is now the benchmark player that the others need to beat.
The sound is wholly organic and voluminous. It is large as if you are in a concert hall. Very much a reference sound as opposed to being overly rich but it so super resolving and true to the music. Flawless in its delivery, I find it very difficult to find fault. As previously stated, I do not have any sensitive IEM’s. There have been discussions that with sensitive IEM’s that there is hiss. I cannot confirm this, I am only passing on what I have read. To me, the noise floor is silent, black and hiss free. The sound quality to my ears sounds like a much higher priced desktop unit, which for me is great because I love to be portable and hate to be tethered.
The QP2R delivers the bass frequencies with impact and energy without any over inflation of the tones. I am trying to put into words my overall impressions of this DAP but it is difficult without gushing and fawning over it. As a reviewer, I probably shouldn’t do that but as a human, a consumer and a music lover I find it very difficult not to gush. It is the best I have heard.
Keep in mind that the QP2R does a great job at playing quality when quality is there. I have found it is not the most forgiving player out there. Give it quality FLAC files and let it work its magic.
