Who knows how it will come down for me. I may get one, or both, or I may just wait around to see what (miracle) @Whitigir will come up with.

Who says he hasn't already?? lol joking I don't know if he has or not. He is very intelligent so I would not put anything past him.

I don't know if I should congratulate you or be worried about you!
That's true dedication!

I fear this might just be true.

At this point, all you are missing is the nuclear launch codes!

Maybe consider getting an Anker Solix C1000 with solar panel then probably you never need to recharge via wall.

My guides are now here: https://npaudio.boards.net/thread/3...zation-guides-discussion?page=1&scrollTo=5014 I have made some updates as well.

On the 3.5mm socket there is an inner plastic sleeve. Does yours have a slight movement to it ?

Yep. I think they designed it to "give" some so as not to be so rigid and break under little stress.

Thank you so much, I’d never noticed before and thought uh oh here goes

Happy wife happy life as they say! iBasso is really changing things up. I can see a lot of time has been spent. There will be more improvements I am sure. I hope this direction of Ibasso tuning continues. You are handy so you can probably change your DX300's if you needed. The only drawback to DX340 is its weight. It almost 500 grams and its solid. I guess not only do you have a great DAP but also a self defense weapon, lol. I took one of mine apart already. ITs very well built. I know the battery life is not going to match the DX300 so you got that one. I have not fully optimized mine yet as I am waiting on something from Paul. My guess with high gain would be max 9 hours. I have gotten over 8 already.

My Root and optimization guides build on what @Whitigir did. There is tons of bloat on the 320 and fair amount even on 340. Two people including @Whitigir have posted that getting rid of the bloats has improved the SQ. I am biased so won't comment. I have never heard a 340 that was not debloated as that was the 1st thing I did. Ibasso stuff lasts a long time. The 340 will last my lifetime I am sure. Just change out the battery when its time. They have switched from EMMC to UFS which are faster memory chips and sure made other upgrades. I have a Dell laptop from early 2016 that I still use - 9 years old exactly come to think of it. Like you I prefer to hold onto stuff that still works well.

I never will need a desktop setup. The super gain mode should drive anything. Its over 2 watts and 8.3 Vrms with 12 V DC. Max is 9 Vrms if I recall. I am sure Steve will mod the cards too. DX340 has battery bypass mode that allows you to use plugged in without destroying your batteries. No other Ibasso DAP has that. Sorry if I sound like a sales person. I would love become a beta tester for iBasso and have some voice and catch the bugs before new product releases. Their next will be D17.

If you want a DAP with changeable battery a DX180 can be had for $300. Its a great DAP for its price, same processor and Android as 340 but has half the RAM. DX260 will give you a better amp and more detail - 8 cirrus DAC chips vs 4 in DX180. 340 blows them away though as I compared them all.

Is there any body knows Steve's, @Npaudio, e-mail?

You are right insomuch as setting the gain settings to medium or low CAN color the sound because the signal is going through resistors. With iBasso DAPs (and most all contemporary DAPs) they are using unity gain. You can see more HERE, but bottom line is that at what is being called high gain, there is no amplification being done. The amplifier is at full power and the gain stage isn't being touched. With medium or low gain, the signal is basically using "subtractive" amplification. The resistors (or other parts and peices ) being used to do this actually de-amplify the signal so that less power is being sent to gain stage. This is much like "subtractive" EQ, but instead of subtracting specific parts of the FR, you are subtracting the power available to the output.

As an example, if you use Mango Player, and EQ, as soon as you enable it, the player will automatically subtract -6dB of gain to help keep from clipping if you add too much in any one frequency. This, though is a software gain, so it is less likely to alter the sound from the output stage.

This is a very simplified explanation, but I hope you get the idea here, and that it is as clear as mud...

High gain is too loud for my IEM. But I should still select high gain and just use EQ to lower the volume right?

The answer is a subjective one, because some people might appreciate the very subtle differences in the sound on different gain levels. Then again, it IS subtle enough that there are those that might not hea a difference at all.

But, to answer your question, if your app has a gain level at the software level, then yes you can do it that way. You may need to enable EQ to do it though (just leave the flat profile as it is; don't adjust any frequency, if you don't want to actually EQ anything). Some apps don't give you this option (e.g. Mango), where others give you full control.

For example, Neutron Music Player not only gives you full control, but also has a feature called auto gain control, where you can set the peak level that the app will consider "clipping" and automatically adjust the gain level to below the loudest sound that would cause it to go over this preset dB. Also, there is the option to leave it permanently reset down if it sees clipping, or you can set it to automatically reset to a predefined level at the beginning of each song. It really is pretty deep in the amount of control you have. You just have to live with the outdated looking UI (which i actually like ).

UAPP also has some manual control. I just find that it isnt quite as much as you get with Neutron IMHO.
