I am spending a lot of time listening to music in headphones lately, so I am thinking of getting a dedicated DAC/Amplifier that would also be capable of decoding Hi-Res Audio. Currently my main source of music is TIDAL, which in addition to its lossless CD-quality streaming and downloads now offers MQA Masters (typically at 96 kHz / 24 bit). In order to take full advantage of that audio format though, you need MQA-compatible equipment. I am looking for something relatively portable, something that would work with my laptop and also with an iPhone, so I could easily carry it around the house and also take it with me when I travel. Hoping to stay within $200 or so. After doing some research, I have narrowed down my selection to these two popular choices: Any thoughts?
