Direct DSD-to-analog output @ 1-bit could be interesting?

 
 
As low as 29,800 yen (250 bucks or so, depending on exchange rate) and 300 bucks off fleaBay

No internal battery and 5V / 500-mA bus power only, just good for mobile and definitely not portable? They also provided drivers for OS X so that could mean no love for both Android and iOS devices. Basically our choices our limited to 7-inch Windows 8.1 tablets or those battery-powered, pocket-sized Windows 8.1 portable PCs from China

Just got one of those and really impressed so far. My Geek Out 450 is in the sale forum....

For clean 5V/0.5A DC power, we could add RAL-EXTPW01

Some of the best micro USB cables out there? Probably a better idea for the desktop version called Super UA

Looks like this units a good for laptop for Djing, I'm a bit disappointed with those external sound cards, even his big brother have this mini USB. 
I don't understand Roland, why not to go with USB 3 or the thunderbolt connection? I mean you guys looking for battery and to connect it to the iphone and I'm looking to work with this unit in my studio with a minimum latency under 1sec.
 
 
Edit, do you guys know what is the opamp under the hood?

Looks like with the latest update you can use balanced headphones.

 

[krikor]

If I'm reading things correctly at Roland's website (specifically in the owner manual for the Mobile UA), it appears that volume control is done in the digital domain, correct?

A member in the Deals thread said this doesn't support flac is this true?

That doesn't make sense to me unless I am just missing something.... FLAC is just a file format with compression (lossless in this case), and ultimately it gets decoded by the host computer into PCM as I understand it, then sent to the DAC.  It's not like a DAC has to understand FLAC at all in any case.

That's why I asked him to explain himself.  Doesn't make sense to me either.

Wow, thanks for the tip -- I didn't realize that... just checked out the manual from Roland and saw that, how cool!  This will be the first DAC/amp I'll have with that capability.

 

[avitron142]

Man... I'm tempted, but until further reviews I can't spend the money Best of luck for all that did!

Doesn't specify MP3 either. Just ordered one (after seeing the post about balanced mode).
 
I have a lot of WAV files but don't wish to convert others just for playback on this.
