SWEET!! Wish I could do that with my RAZR MAXX. I have all 3,800+ Jazz CDs ripped with EAC (Secure Mode, Test & Copy, no C2 and on a calibrated drive), and converted to FLAC. I could see myself doing this.

VentureCraft sees potential in Android & standard USB audio.
VentureCraft delays the release date of its latest headphone amplifier Go-Dap X in order to modify it so that it can interwork with the Samsung Galaxy S3.

"Go-Dap X releasing date in stores will be on Sep. 25th due to this Galaxy S3 modification."

AudioQuest Bumblebee Android DAC:

"Designed specifically for Android devices
24-bit ESS Sabre conversion chip
Supports all music files including 24-bit/192kHz lossless
Drives headphones directly with 3.5mm mini-jack output
Fixed or Variable output modes
Asynchronous transfer for accurate digital timing
64-position (computer-controlled) analog volume control
Isolated dual master clocks
Colour changing LED to indicate source sample rate"


I am wondering if the AudioQuest Bumblebee Android DAC is a standard self-powered USB DAC or an Android-specific USB DAC.

The AudioQuest Bumblebee should be likely an AudioQuest DragonFly with built-in rechargeable battery, because it "supports all music files including 24-bit/192kHz lossless".

And an Android-specific USB DAC can support only 16-bit/44.1kHz:

If the AudioQuest Bumblebee is a standard USB DAC, while using with a PC or a Mac, the sound quality of the AudioQuest Bumblebee should be superior to the sound quality of the AudioQuest DragonFly thanks to a clean battery power.

About Android-specific USB audio:
"As of now, the standard Android releases do not include USB host support. Samsung decided to add this feature on their own. The Android folks are working on a funky USB dock protocol that works over USB (sort of like what Apple does) that, frankly, most of us developers think is stupid. There is certainly a push to put USB host support for standard devices (like audio, keyboards, etc.) into the normal Android releases."
