LG V20 Sound Quality

[malifact]

  sound tuning of v20 with B&O logo is done by B&O and according to some China forumer the sound is more like “plain water" compared to that of lg tuned v20.
not really sure what "plain water " means but I guess it mean less sound coloration .

 
If I translate that back into Chinese, then yes I think he/she meant the sound is less coloured. It's interesting because I find the B&O tuned LG V20 to be coloured. Not by a huge amount, but there is definitely some elevated bass and treble. If the LG tuned V20 is more coloured, I'm glad I didn't get that model.

I am aware that higher gain does not inherently equal better sound quality. Perhaps I should have said "if it is not loud enough, try the aux trick." Similarly, he can freely ignore whatever advice I provided if he plugs in the headphones and they are perfectly adequate from a volume standpoint. 

Even if it is loud enough, try the Aux trick anyway. Some headphones really shine with the extra power.

Poweramp users - For some reason the volume I'm getting in Poweramp is much lower than in other music players. This is true both for the release version and 3 Alpha (builds 703 or 704). And it doesn't matter if I choose the Hi-Res output, OpenSL or AudioTrack.
I don't use DVC (direct volume control) on it because that introduces an EQ not to my liking at all. 
I know I can use the preamp, and to achieve the same volume as other players I need to turn it all the way up.
Is this normal? Is there a downside of using the preamp?

I just tried poweramp v music and the volume levels appear the same in normal and high impedance mode.

Avoid the preamp as it can allow clipping

I'm just stating from my own experience with my V20 and the B&O earphones.
I'm not creating a topic which has to be technical or scientifically proven with measurements and graphs.
I was just "wondering" how the adapter works to trick the DAC into triggering the higher mode.
 
All I asked was a simple question and would like a simple answer...or as simple as can be explained.

 
I've already suggested how it might work.
 
But it looks like the H3's cable is not detachable and it has an in-line mic/remote so that will prevent them from ever getting high mode.
 
Even if the cable were detachable, we'd still need to know the ohm rating of the adapter (perhaps you should PM the guy who it worked for and get a brand/model#).
 
Don't understand why you're asking us if an unspecified adapter that someone found in a box of old cables will work to trick the phone into high power? Given the lack of info on that one piece, how could we possibly know?

My inline volume control has a mic and works.

It depends on the mic connection:http://forums.androidcentral.com/samsung-galaxy-s3/189523-final-soultion-why-most-headsets-won-t-work.html

Will try to break this down here. The inline volume control is nothing more than a potentiometer. A potentiometer (or pot) is essentially a variable resistor. When the pot is at maximum volume it is adding zero resistance. When at zero it is adding some amount of resistance that is the maximum value for that pot. Pots come in different values from 1 ohm up to 1 megaohm and beyond. Different values are needed for different applications. So if the total resistance of the headphones and pot turned to zero is greater than 50 ohms, the V20's high gain mode will be activated.

Also as to volume, pots come in different tapers. There are linear and audio taper pots A linear taper pot would increase the volume in exactly a linear fashion as you turn the volume up. An audio(log) taper pot's volume increases in a way that would be more natural to the human ear as you turn the volume up. There is also inverse log but won't get into that here.

That is a very basic and simplistic explanation.

Hope that helps

I probably should have mentioned that it was using my car's Bluetooth. I haven't made the comparison through the headphone jack. I will ty that next

Poweramp has an option to follow the bluetooth receiver or not. I'm not sure if the in house music app does, as I think bluetooth is the devil's arse sweat.

LOL
I use Bluetooth only in my car, it's a hundred times more convenient than aux. But I have to say the sound quality is pretty good. And it's not like I have an audiophile car stereo...

What does it mean "follow the Bluetooth receiver"?

It means the receiver can control the volume in the transmitter.  In this case the car could control the volume on the phone.

I can't find that option in the poweramp settings. Can you maybe point me to it? Also, the volume control of the car changes the volume of the car stereo and doesn't change the phone volume. The Bluetooth volume on the phone is set to max.

Settings/Audio/Advanced Tweaks Bt Direct Volume Control.
 
Not all bluetooth receivers have this feature, but I thought I may account for the difference.

OK, so I don't have "BT Direct Volume Control", just "Direct Volume Control", and it affects all outputs and also adds that EQ with the bass and treble boost that I don't like.
 
On the Poweramp F.A.Q it says under "volume issues" -

Poweramp uses Direct Volume Control (DVC) by default on 2.3+ mid-to-high end devices.
On stock ROMs this produces much better audio output due to the extended dynamic range, this especially helps to get extra powerful bass and also
maximum loudness of Poweramp is not limited by preamp and is similar to stock player.

 
So that implies that without DVC the maximum loudness is not the same as some stock players. I wonder what Poweramp does differently from other players, because for instance PlayerPro has the same gain of the stock player.

So, I got my P9 today and did listen about an hour switching between LG v20 and Hugo. First of all, P9 leaks quite a bit, so if you are thinking of using them in a pitch-black-noise-free environment, with over 50% volume of the LG v20 people might probably guess what you are listening to.
 
Second, I really liked the setup with my LG v20 B&O, listening to Chick Corea's Ultimate Adventure (16/44.1) and The Vigil (24/96). Also some 24/96 solo piano. Did not burn-in my brain (!) and the P9 yet. As it is very satisfactory. I don't need any increase in the power, so no need for an impedance adapter. Just listening to 'City of Brass' right now and the sound stage and instrument separation sound fantastic to my ears.

OK so it looks like Poweramp has lower volume vs the stock player / PlayerPro even from the headphone jack. It's not related to Bluetooth.
Also, the Hi-Res output (3 Alpha build 704) is failing and reverting back to the default output... is it just me?
