Yup, it would :)



Our most affordable reclocker - iPurifier3 - is a "baby" nano iUSB3.0, which is a "baby" micro iUSB3.0. Different performance levels and prices, but the same core job.
Thanks. I need something that gives out a clean 5v so I need either the Nano or micro. I have another doubt. Will they work with my focusrite Scarlett 2i2 ADC, just the same way they work with my dac? Or is the data just one directional? For adc, my source for data will be from adc, but I'm assuming pc noise through the ground lines remain similar.

AFAIK ADC devices turn analogue signal into digital, and our USB sorters send out digital signal. What ADC do you have if I may ask?

Focusrite Scarlett 2i2 gen 1 I guess (need to check if it's gen 2). It connects to my pc via usb. From my understanding (correct me if I'm wrong) the two issues I know are

1. Timing, slew rate and noise issues on the data line that makes it harder for the slave phy causing it to go into a high power mode making it more noisy and getting that noise to the rest of the chain. Don't think there will be an issue since the adc is the master here, and the slave pc isn't going to do a linear task, just a digital task. (Unlike dacs where the slave will be doing an amplification task which relies on a good linear behavior and not just cut offs/thresholds).

2. Ground plane noise which can accumulate from any bouncy ground plane since almost all ground planes are connected in some way (unless isolated by expensive means).

I was assuming the ifi would improve the second thing wrt adc too. Also my adc uses usb power so that's another improvable parameter when I give a cleaner 5v supply.

Hello
I purchased a Fiio Q1 MKII to used with my Galaxy S4, before I found all the info on this thread. Since i haven't read anything about this specific combo, my results have been:
1) Galaxy S4 + Fiio Q1 MKII, Only works with UAPP
2) Galaxy S8 + Fiio Q1 MKII, works natively. When using UAPP, make sure you exit out of UAPP to release the DAC. I use Spotify and need to do this to get sound from Spotify.
3) Galaxy Note 9 + Fiio Q! MKII, works natively. Make sure to exit out of UAPP to release DAC.

I would like to use my S4 as a DAP due to its size and replaceable battery and I found a Pyle PHE7AB. I read that its a rebranded Fiio E7, so i should be good. Cabling might be annoying because it uses mini usb b.
Can anyone recommend any other battery replaceable android phones with a 4.7 inch screen (or about that size) and micro sd slot that might have ok DAC support?

How about a LG V20? It's bigger but the last great phone (it has everything) w/ user replaceable battery IMO.
And you can find still its battery in amazon.

Here is the specs: https://www.gsmarena.com/lg_v20-8238.php

Nope. It has a built-in ESS Dac you can access it thru UAPP or Neutron MP.
Yes you can use it as a stand alone DAP. No problem with IEMS or some sensitive cans.

Using it for 3 years now as my everyday commuting phone/DAP. For extended trips i use a more powerful DAC/AMP that I attached to my V20.

It has dedicated thread here: https://www.head-fi.org/threads/lg-v20-sound-quality.816024/
