Would appreciate your input if anyone has experience with Geek Out:
Has anybody been able to get the Geek Out to work with Sony Xperia Z series and UAPP without the need for the above procedure, and if so, what kind of tweaks to the phone or UAPP settings were needed?
Or with any phone with Android 4.x and UAPP, for that matter?
Yes, I have made it work with Xperia Z2 on Android 4.4.4. UAPP works fine as long as it is the first app you run and Geek Out 450 the first DAC you connect on the phone. No need for power bank or anything.
BUT. It is very selective when it comes to earphones. Connecting the IEMs that came with the phone is OK, if I want to connect my "hi end" IEMs Sony Mh1 I must use the 47Ohm output, not the 0,47Ohm which should in theory be the correct connection for them. Otherwise the connection breaks.
Walkman app can control volume on the Geek, but only when it plays files via the DLNA server (go figure...). Files from the SD card or the phone itself are played in full volume. Hiby App can control volume too. Most of the times. And sometimes, no matter what I do , the connection breaks, there is crackle and pops, and another IEM pair bites the dust.
I have practically given up on Geek Out 450 for use with an Android phone. I use now the idsp and miss nothing. The dSp sounds just as good with IEMs on the go, it has no connection issues and you run no danger of frying your IEMs. And it is barely a third of the price of the Geek Out.
