It's definitely a matter of taste. I have used a few of their amps, and for me personally, it makes a world of difference in the audio quality worth the effort.

It's definitely a matter of taste. I have used a few of their amps, and for me personally, it makes a world of difference in the audio quality worth the effort. Several types of headphones simply can't be driven by most phones directly. I've even gone as far as using my phone's OTG USB feature to hook up my amp as a DAC, which is admittedly awkward in my pocket. But to your point, I would miss my convenient streaming options. A good compromise are amps that use a high quality bluetooth connections, like EarStudio.
