    Has anyone measured the output impedance on this amplifier? The product description on Sony's website doesn't tell me anything.

    Most people guess it is approx. 10ohm as it uses the same TPA6120A2 chip as its older brother PHA-1. But I am okay with it using ATH-M50x. Sound quite bright.

    LOL! but yeah, a case would be good, as the frame gets scratched or dented easily

    New phone (Sony Xperia XZ) with USB-C connection. Tried a USB-micro to USB-C adapter but didn't work. Xperia XZ didn't find PHA-1A. Any idea what's the problem?

    Ahhh yes, the lovable Android ecosystem.  I've found that about half of the devices I've tried do not work w/ external amps over usb, like the PHA-1A, HA2, C5D...and half do work.  I had issues w/ phones like the Galaxy S7, but the Pixel and the OnePlus 3T work perfectly.  Go figure.  It's how each manufacturer decides to send audio over USB.

    Maybe something with USB-C adapter not OTG compatible?

    Help please.
    Need OTG cable (preferably no adapter, like the one that came with Oppo Ha-2) that will plug straight into an android phone and Sony PHA-1A or PHA-2A. I want to buy one and have looked into the documentation online, I don't think there's an otg cable included in the package. Included is Micro-B cable for pc/mac connection and cables for Xperia and Walkman.
    Please note, my phone is NOT a type C, so I don't need recommendations along that line.
    Hope someone can help.
    Thanks.

    Micro usb is the same port for android, xperia and walkman device. I've used the xperia walkman cable on my samsung J7 no issue at all. In contrast, usb port for apple products is not that great. My ipod touch will not recognise my PHA 1A whenever i pause my songs on the lockscreen and need to plug in the cable again or turn on the amp again. Anyone have this issue?

    How is this AMP/DAC compared to creative Sound Blaster E5 considering the sonic quality, Of course the Sound Blaster E5 exceeds Sony in functionality and settings but i'm concerned with the sound quality

    Got the same setup. In the phone u need to press check for USB device. Than it works normal

    Soundblaster sound really bad compared. Creative is not known for producing really quality stuff

    Had it well over a year, and it still shines. Would not need to upgrade even with the Audeze entry phones.
