  1. Great review thanks, i just got the new FIIO BTR5 ( portable high fidelity BT amplifier ) i been using it with my IEM Campfire Polaris2 and my Shure SE846, using my iPhone 11 Max as the audio source and i tell you sometimes is hard to tell the difference when using my Astell & Kern SR15 wired (2.5 balance or 3.5 cables )
    it seems wired and the bluetooth gap is getting closer for a fraction of the price i guess i won’t need my Astell&Kern no more.
