Definitely the best sounding dac amp i know to date that doesnt break the bank too much. It is just the QC man. I have to replace serenade to get the QC right. Mine was heavily imbalance to the right chanel. Tried some demo they also have the issue. Until just now i got my replacement and everything is perfect. Damn Hifiman QC.
Yea, luckily I have had no issue other than low volume noise which I believe is par for this device. The more i listen to Serenade the more I'm convinced about the performance. It is simply an incredible sounding DAC.
