I'm looking for a more powerful USB Dac/Amp for my wife, she likes it loud. We are currently using this Dac/Amp:
It works well and is a huge improvement over just the phone itself but she wants it to be a bit louder. The Dac/Amp needs to be portable and preferably have it's own battery instead of relying on the phones battery. I'm looking at something in the $200 range but would spend more if nothing is available.
These are the IEMs she is using:
MEE Audio Pinnacle P1
These have a 96db sensitivity and are 50 ohms and the amp puts out >190Mw @ 32ohms and >75Mw @ 150ohms. I thought about a dedicated portable player but she uses a lot of different Android applications for music so we're stuck with the Galaxy S6 Edge until the end of this year.
