Backlash wroteSo~, I recently bought a FiiO BTR5... For those unfamiliar, it's basically a miniature Bluetooth-connected DAC-amp. It pushes a pretty stout 250 Watts, according to the product sheet, though word is it can go to 300W, and drive an HD600.
I have to say, for once, it really does live up to the hype. The battery lasts for two days powering my WH-1000XM3's, and it offers a full range of Bluetooth protocols to sync with your phone, though a USB C>C or A>C cable makes it great for laptops. I hooked it to my laptop running the latest Pop!_OS, and it works flawlessly.
I will say the Sabre DAC in the device has a slightly different sound character to the Burr-Browns in my iFi equipment~... Less laidback, and less warm. One instance stands out to me, when I noticed crisp cymbals in a live recording, wherein they were muted before. It's possible this was just a problem with my EQ curves, so this is just a curiosity. ^^'7
I also bought a pair of DT 770 Pros, the 250 Ohm versions... I'm still playing with EQ presets on them, so I'll get back to y'all on them.
The FiiO looks pretty cool! Though I do wonder, just how much better one of those is than, say, an LG V50. Although... looking at pricing, I might have just answered my own question ^^'
