Using Hi-Fi Quad DAC with Impedance Adapter - LG V30 Questions & Answers

Hello guys
I have ordered impedance adapter from ebay the one @ChazzMatt have mentioned at many posts
Before using that i wanted to ask that will it work fine with custom mixer path tavils file that is included in anxiousv30 which provides dual speaker and volume boost
or will i have to restore the original mixer path tavil stock file
also can i use impedance adapter with aux cables in car or not ? i mean its safe or not ?

Really don't need High Impedance.
Also don't use the adapter with AUX cables. I'm honestly trying to figure out why anybody would do that in the first place.
Edit, when plugging in the AUX cables, the device will go into AUX mode.

The V30 in aux mode outputs the same level at max volume as my desktop Teac UD-301 DAC. You do not need more.
The whole boosting to high impedance mode is foolishness.

There are some headphones that need the 2 Vrms power of HIM vs the 1 Vrms of Aux mode. Planar magnetics in particular require a lot juice.
Playing at a lower volume level in HIM as opposed to at max volume in Normal or Aux mode may also slightly affect SnR, although we haven't been able to measure that objectively.
But I agree that going through hoops to force HIM with high sensitivity IEMs, only to turn volume way down is, well... :cyclops:
There is a persistent myth, going back to the V10, that HIM is needed to (fully) activate the ESS DAC, and that's what drives it.

He was asking for his AUX cables for his car.

I figured out why not to long ago.
LG is marketing high impedance as pure HiFi without mentioning the type of headgear that is giving high impedance. It's just marketing gimmick. Sure, full sized cans will give better sound while also going over 50 ohms. It would have been awesome if LG actually explained what they meant by having a better experience on high impedance.

Yes. I wasn't so much responding to that. I was merely pointing out that, while most of the HIM chasing is indeed unnecessary, there are a few cases where the extra power is needed, and where HIM is not triggered automatically.

Oh I agree man!
I also did a test on my 30 ohms IEM. Used an adapter to trigger high impedance. Talk about degrading audio quality.
All the people chasing high impedance is from misinformation. However as you always point out, some gear needs it though.

Ok so i currently own a pair of kz zs10 which have 32ohm impedance so i guess using adapter with them is going to be worth it or not?

I used it with high quality 35ohm earbuds, but then later after rooting, I used Anxious V30 module to get forced HIM. So, I no longer need to use impedance adapter to force HIM.
This quad DAC will try to give you the best sound, depending on what you have connected to it. So, that's why some say you don't need the impedance adapters.
But the impedance adapters are just to do what the Anxious V30 module does (force HIM or the equivalent) or whiskeyomega's audio mods. If people don't want to do that, they don't have to.

Noooooooo
The distortion is horrendous! Mostly I guess due to the BA. You don't want Anxious mod either. You can possibly kill the IEM's. I would HIGHLY recommend not using a mod. You don't need forced HIM with the KZ.

Also take a look here,

I showed SS of the 3rd party cable I bought for my CCA C10. They can also be used with the KZ ZS10 Pro.
However, I have another cable on the way just for the KZ.

Obviously you have a choice of whatever color you want. This particular color is out of an aesthetic choice. The cable is for audio. I also noticed I set the volume down lower with the cable. You do get a bit of volume boost . If you find the volume not loud enough, it's because of stock cable.
This really does help the KZ and CCA sound better. I've tried every genre of sound. 3+ hours going between songs and cables and both IEM'S. So it's not placebo.
I can always host high rez files that I used. Just pm me if you want some good examples.

My doubts are, can i root my V30Plus even after Pie update? is it possible.
And also can i update Lib files for DTS?

All V30 variants can be rooted.
ROOT Your LG V30!

The Root Sticky specifically talks about DTS. . Bottom of post #1.

I use my phone with 16Ω, 32Ω and 60Ω IEMs/Headphones and I don't care about impedance mode. Sound quality is the same whatever mode you're in, it just gives more power/volume that's it.
If you feel that your headphones are underpowered even at max volume, that's when you should think about these hacks. In most cases it's useless and not recommended.
