If you're asking about the AMP (not the DAC/Amp combo), I really like the sound of RSA amps. I own a Predator (it's a DAC/Amp), but Ray also offers amps only: The Hornet (http://www.raysamuelsaudio.com/products/hornet), The Tomahawk http://www.raysamuelsaudio.com/products/tomahawk and a few more).  They are noticeably on the "dark" and "warm" side of things though, so if this is not your cup of tea - look elswhere. To my taste, RSAs easily better similar iBasso products, but everyone's taste is different. 

 

Another great option to consider is HeadAmp Pico family. http://www.headamp.com/pico/pico_amp/index.htm I haven't owned one, but quickly auditioned once. Great sound, lighter and more open than RSA, but as a consequence a little less "substantial". I heard only the original Pico, they offer the Pico Power now, which is reported to sound noticeably better.

 

With no offence ment, I am personally not a great fan of FiiO sound. I admit they make some really great products for the price, but other amps simply sound more to my liking.

 

I hope my suggestions fit your definition of "mini" -)

I'm really interested in your experience with the hifimediy dac, since I'm considering to buy the one with the headphone out LINK. Keep us updated.

Thank you. I'm sure these amps are great but really out of my budget.

I bought that same one and it should be here this week so I'll let you know. I'll be using it with my 2012 Nexus 7, 2013 Nexus 7, and Galaxy S2 (SPH-D710) though I'm 99.9% sure it won't work with the S2.

Android device & upcoming Light Harmonic GEEK:

"Android compatibility anyone?  No need for external power!  Larry estimates 12 hours of high resolution music enjoyment on a single battery charge.  Wouldn't it be great if Apple would let us do the same thing with iDevices? :)"

 

Galaxy S3 > USB audio out >> USB OTG cable adapter >> Light Harmonic GEEK USB DAC/amp >> headphones

Awesome news on the Geek.

I saw this too and am very excited, however I would like them to clarify the high def part of it.  Most if not all programs downsample any hi res files to 16/44.  I think it has to do with the Android OS.  I use Poweramp and while it reports my hi res songs as 24/96, my DAC is telling me it is playing only at 16/44.  UARP is the only way for now to get bitperfect out of an android device.  I have a NOTE II, which has a near identical USB audio implementation as the GS3.  

 

I'd like to be wrong, though at the moment it doesn't matter as long as the sound comes out and it sounds good since I have very little hi res music.  At any rate, I have a GEEK ordered and will report back next year when I receive it.

Just downloaded a 32bit 384Khz wav test file from this page:  http://www.msbtech.com/support/supportHome.php

(middle part of page, right side)

 

USB Recorder Pro recognizes only 24bit 384Khz on Sony Xperia Z with M2tech Hiface Dac.

 

But hey! No complaints....:wink_face:

Slim Bean is my favorite AOSP ROM.  That and Liquid Smooth which is based on Slim.

Holy Hell Yes

I loaded this rom on my AT&T S4 last night and it is all the rom I could have asked for! It is loaded with all the features, looks great, and drives either a USB DAC or headphones from the usual output port as well!! (jacknorris's patch did get me pretty much to this point before, but the regular headphones port didn't work...)

I've literally been wanting to drive a USB DAC with a portable device for like 5 years+, and now it's here! Thanks for the heads up, CZ Eddie.

USB audio is not yet implemented by Google.

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/2625#post_9614979

 

Google can’t put limitation on something they don’t implement.

 

As Android is free and open source, Android device manufacturers (Samsung, HTC, Sony, LG and some others) modify the Android OS and implement their own USB Audio by leveraging on the free and open source 32/384-capable Linux USB audio driver for ALSA.

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/2985#post_9762071

 

So far, these Android code modifications are limited, and the generic music players have to use the current Android media player framework having some code instructions which prevent the usage of 24-bit audio format like

 

if( ! (audioFormat->format == AUDIO_S8 || audioFormat->format == AUDIO_S16) )

 __android_log_print(ANDROID_LOG_ERROR, "libSDL", "Application requested unsupported audio format - only S8 and S16 are supported");

 

http://www.head-fi.org/t/595071/android-phones-and-usb-dacs/1005#post_8950416

 

 

LG will carry out some more modifications

 

 

 

 

 

 as well as Samsung.

 

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90

 

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90

 

 

eXtream Software Development has chosen another way, playback music player directly interfacing to USB audio soft-driver, so that their USB Audio Recorder PRO is able to playback hi-res music on stock USB host-featured Android devices.

FiiO E07K works with the Note 2 after turning off USB charging on the Fiio:

I was hoping, if I may, to move the evolution of this conversation back a few millennia by asking : How do I get music tracks into USB Audio Recorder Pro?  I`ve got everything set up : HTC Butterfly, OTG cable to new D-Zero SE (sabre DAC) and of course USB A.R.P installed and looking very professional. But I can`t seem to access any of the files on my SD card . . .   

 

I`m sure I`m doing something utterly infantiley wrong.

Are your music files FLAC?

post #3103 of 5762

I finally got USB Audio Recorder Pro working on my Note II again.  A VERY pleasant discovery is that UARP has hardware control over the volume control of the HRT Microstreamer.  What this means is that there isn't the hiss that I get using the MS on the Note II without UARP (amp is at full volume, with digital attenuation - bad!).   Unfortunately, there is a clicking that occurs every few seconds that is mildly distracting.

 

I also decided to go from FLAC to mp3 for my portable music collection to conserve space, forgetting that UARP doesn't do mp3.  DOH!

 

On a side note, it is too bad that something like Pandora can't be routed through UARP.  I listen to it quite a bit, and the main DAC that I will be using (HifiM8) won't work with the Note II without UARP.

Do you get the message "USB audio device initialized"?
