HTC One and Samsung Galaxy S4 both work with Leckerton UHA-6S.MKII via USB-OTG straight out of the box. I got the One first then returned for the S4. This is AT&T version to be specific.

Just bought the UHA-6S.MKII for my GS3 and others.

 

BTW, has anyone tried this otg cable?

Great. Just purchased two of those for Leckerton+GS3.

Anybody know if there are different lengths of this cable. Need 4 inch.

I believe they only have the one length at the moment.

I got the iUSB, and it worth every penny.

I've really been trying to get a handle on this, but I couldn't find any clear answers so far. From this picture though, can I gather that ANY usb-DAC (Leckerton, Glacier, Vamp-Verza, PD-XM6) is going to be able to do 24bit 96/192 off of my Galaxy S3 (and soon to be S4)? Because from this picture that's all that's really going on, just got a bunch of iFi products in there, isn't it? Oh, and by "can do" I mean can they output 24bit 96/192 without down-sampling to 16 bit 44.1/48?

post #2290 of 5575

Yes android down samples, but USB recorder recorder pro allows a 24bit data stream (I think, as I havn't tested it)

Japan released Docomo galaxy s3 alpha (running stock jellybean) works with Leckerton UHA-6S.MKII via OTG no fiddling. Received the leckerton yesterday, I still need to hack some cables to length.

The PD-XM6 doesn't I beleive do 24bit my memories a bit hazy but Im pretty sure it upsamples 16bit to 24bit but doesn't do 24 bit natively, the apex glacier does though.

The Leckerton DAC can take up to 96 kHz, 24 bit files through its SPDIF and Toslink inputs.  USB audio is limited to 44.1/48 and 16 bit, apparently to ensure it works well with as many portable devices as possible.  And it does work extraordinarily well with the S3.  I've only had mine about a week, but I couldn't be more impressed thus far.  It projects an even larger sense of space than the Headstreamer, which was my previous champ in this regard, but seems to have the neutrality and impact of the Pico.  Thought the latter comparison will have to wait until I get my Pico back from Justin.  I'm having him mod it for use with Android.

 

All three of these units suggest the DAC chip is just a slice of the pie in terms of DAC performance.  Implementing the chip is paramount.  You can't assume that a Saber chip is going to guarantee a good DAC.  Likewise, the Headstreamer and Leckerton end up sounding damn near, if not as revealing as my desktop setup, despite using chips of modest regard.  People also expect the Pico to sound less good than units with two Wolfson chips, or those with asynchronous DACs.  And yet, the Pico usually sounds better.  Perhaps it's best to find engineers of preference rather than chips.

"Avoiding stock 16bit/48kHz low-resolution audio system" => avoiding the Android media player framework by using the USB Audio Recorder PRO app.

 

As far as I understand, the current release of Android media player framework decreases or increases the sampling rates of music audio streams to 16/44.1 in order to mix easily these audio streams and 16/44.1 Android system sound (ringtone, notifications …).
