Android phones and USB DACs - Page 114

post #1696 of 6992

I noticed this has been asked but no answer yet.

 

Does the Galaxy Note 2 work with the Schiit MODI?

I was looking at getting this but may go with a portable for now.

 

For a second question as there is a huge list of options and I'm new to all this.

Which would be a good option for driving Hifiman HE-400's or Mr Speaker Mad Dog with Alpha Pads

Thanks for the help

Thanks again for your help.

 

E7 definitely works with the S3, used it with my US and International S3s. No idea whether it is better than than the D-Zero though.

I figured your Belkin hub would be a good place to start auditioning for a working setup.

 

Will also be researching USB battery packs to provide power rather than relying on AC->DC adapter. I don't suppose anyone has an input on a 4 port USB Battery pack vs a 2 port USB Battery pack and whether the 4 port model is more likely to interfere with the digital audio signal going from the android device to the powered USB Hub to the USB DAC. Battery capacity, voltage, amps etc is identical for both models. For all I know the number of ports is irrelevant to electrical disturbance.

 

Thanks

 

 

My Belkin powered USB hub is the following:

It was the smallest USB hub I found in the shop around the corner.

 

 

About electrical disturbance, a solution: USB Y cable?

“What’s wrong with the current USB cable design for audio use?

Many cables combine power and data into a single cable, causing crosstalk between power and data.

iFi Solution:

The key of course is the “twin connection” design. It separates the signal ground from power ground and shields the signal and power connections from each other."

 

 

The most constant voltage-regulated USB battery pack?

http://www.6moons.com/audioreviews/kingrex9/2.html

 

"The battery supplies of the usual mobile equipment require a DC/DC converter to step up the required output voltage."

 

 

 

"Our U Power's two 3.7V cells net 7.4V power which gets stepped down to the 5V with a superior low-noise linear voltage regulator."

 

 

 

"A typical linear regulator diagram is shown in Figure 1-1. A pass transistor is controlled by an operational amplifier which compares the output voltage to a reference. As the output voltage drops, the op-amp increases drive to the pass element, which increases output voltage. Conversely, if the output rises above the desired set point, the op amp reduces drive. These corrections are performed continuously with the reaction time limited only by the speed of the op amp and output transistor loop."

There’s a 99.999% chance that a Galaxy Note 2 can interwork with the FiiO E7.

 

The following reviewer prefers the iBasso D-Zero:

And a USB OTG cable is included in the box of the iBasso D-Zero.

There is no answer because nobody knows it.

I NEED one of these. Will make my life a lot easier!

post #1706 of 6992

so like one of the guys said yesterday (topic keeps getting ignored)...how do you get hot plugging functionality working on a Nexus 7 (grouper (wifi))???  It works only if you reboot the device with the DAC plugged in.

 

I've tried on ParanoidAndroidROM, LiquidSmoothROM, and now Dirty Rootbox ROM with multiple kernels (M-Kernel, Motley, Timurs)

there was actually a link to a mod (that i have yet to try) that solves it on the last page

I know I post there under the same name (in that thread already mind you).  Already tried that. :(

I have a stock, US version Samsung Galaxy s3 and an iBasso D-Zero. I know that these are 'compatible' with each other, as in I'll get that beautiful clean sound, but I don't know how to hook it up. Which cable do I use? Where does everything go? Once I connect it, will it work automatically, and I'll get the amazing sound, or do I need the USB Audio Recorder Pro app thing. And can I use this with Neutron Music Player? 

 

Thanks!

You need a USB OTG - 'On The Go' cable. They can be bought off ebay for a couple of dollars. You should be able to play music through Neutron with this amp.
