Power Amp question - Getting the most out of the audio

Helllo everyone,
I have read about supercurio's audio analysis and how the audio chip in the GS2 might not be as great as the original GS but I have a GS2 so...I am trying to get the most out of the audio that is in there using headphones and my car stereo through auxialiary input.
I currently have both power amp and dsp manager installed and was wondering if dsp manager was necessary since power amp has a built in equalizer. I was also wondering if anyone had a nice equalizer setting that works well with the GS2 for most type of music
thanks!

So then you recommand using only audiobooster and disregard poweramp's equalizer and dspmanager?
Does anyone still have some good equalizer settings? I am currently using the Rock preset on poweramp and am liking the difference between it and flat but I don't know if I could do better.
thanks

bump,
no audiophiles here have a nice audio setup to use with headphones or through aux?

I'm far from an audiophile..
I could test mine with my Sennheiser HD 555s when I get the phone next week but thats not really what you'd want. They're not really something you'd use with a mobile phone.

mainly looking for someone who has experience with the phone and with equalizers to try and bring out of the strength of the phone and maybe hide the weaknesses if at all possible.
Someone recommended Volume+, would you only use that or use it with something else

I grabbed hold of volume+ after reading about it here. As Voodoo sound doesn't work, I'm using it to boost the base volume of the headset only. If I want to fiddle with the EQ, I have PowerAmp for listening so will use that. To be honest, these two in combination seem to work pretty well for me with fairly cheap headphones so I'm happy.

PowerAmp's EQ is the best, no question. Don't use any additional resident EQ's, they are very low quality compared to PowerAmp's one. After tweaking the poweramp EQ some, I'm getting a pretty good result with my etymotic HF2's.

can you post the equalizer setting you are using? Just to give me an idea
thanks

Poweramp working well. Is it much improved by also using external equalizer app?

poweramp works fine and its amplifier too is ok
however this wont fix the audio output of the sgs2
plug any decent headset (maybe not the bundled one) in the sgs2 then the sgs1 or an iphone and you can easily hear the difference even if youre not an audiophile or smth like that
personally this will make me jump to the next nexus or sgs, granted that their audio output is better, as soon as they're released
its not that the sgs2 output is horrible but its far from the leaders in that area

I'm using the settings described here.

They work rather well for me. Sometimes the output isn't loud enough though, so I've been playing with some of the equalizer and volume+ settings. I can jack the volume up a ton with those two, but I definitely lose some quality here and there and see a bunch of volume+ force closes so still working out the kinks there. Other than that, very satisfied with the audio quality on the SGSII with Poweramp.

+1 to these settings
im using the phone as my primary source for audio in the car, using poweramp and i find that the settings described in that post work quite well
the only thing to note is im not sure if the EQ settings work as it says that only the paid version can use custom settings but it seems to do something at least

weird audio with headphones

whenever i plug in my headphones (with button controls) it is screws up the EQ settings
the sound is a bit lower and the vocal is very low, but whenever i push the buttoncontroll and hold it, the music sounds normal as it should
i tested this with another headphone, same result
how do i fix this??
im using aokp m5 and semaphore 1.1.1

I guess you ae trying to use headphones that are dedicated to iPhone.
You need converter. Something like Fiio LU1 (or LU2).

nop its not dedicated to the iphone, i used the same both headphones on my nexus one and there were no sound problems, it only happends with my sgs

Try to change Kernel, and use one that fully supports Voodoo Sound and download from Play Store the voodoo control app...
It's the only suggestion that comes into my mind right now.

You are using headphones that are wired for iphone.This is your problem.End of discussion

I bought some headphones last year, they were designed for iPhones. I found the sound quality very poor but they came with a little add on cable called a neutral stereo plug. With this cable the sound quality is a lot better.
The button on the cord, when depressed made the quality better, so it sounds as if its the same problem. My headphones are Urban ears.

Back speaker noise on new Nexus 7 (2013) on low volume

When playing sounds or music at very low volume there is an interference noise that can be heard if you put the ear next to the speaker. I've tested it with the game Mystery Room. It's very annoying when you are on a quiet environment.

Another thread in xda: Static / buzzing from speakers at low volumes
siraltus said:
It's because the Nexus 7 uses a crappy digital volume control that simply reduces the volume of the digital waveform before it hits the DAC, instead of having a real analog volume control -an op-amp that adjusts the volume of the signal before it hits the headphone/speaker amplifier.
What you're hearing is quantization noise as at the lowest volume the audio uses only 2-4 bits of dynamic range instead of the full 16 (or 24, dunno what DAC is in this thing). It's the same as the bit-crushing effect you hear in some dubstep and other electronic music that degrades the audio into a robotic crunchy mess, only here it's not on purpose, it's just cheap design.
There is nothing you can do about it.

Thanks for consolidating everything and giving people an easier way to learn about this issue.
The best way I believe to produce the static.
Play YouTube Video > Adjust volume to mute > Listen to top speaker (portrait mode) > Then gradually increase it from mute and up
I was at a BestBuy and I was still able to hear it, the Aug/Model I bought and the floor model they had, both have the static.

OMEGA rom, Sound louder but quality lowered. How do I fix?

I've found since moving from stock to omega sound is louder but less quality output. Is there a reason for this?
As when I revert to stock rom this issue is not present

You'll need to edit the "snd_soc_2x_Fusion3_auxpcm" file. Search for a thread about volume boosting and which values to change.
In your case - the digital volume ("headset") will have been increased in that file to around the 70% mark, therefore you'll need to decrease it back down to around 60%. From my experience, once the digital volume gets above 65%, and you listen to VERY sensitive i.e.m's at low volume you may be able to hear 'swooshing' 'buzzing' noises where the S4's amp isn't providing much power to them as you're probable on the bottom few notches of the volume slider (analogue amp) and the increased digital volume is giving you artifacts in the sound.
Full size headphones and aux equipment generally will not be a problem as you tend to boost the analogue volume higher for them towards the top of the slider- therefore providing more power from the amp - plenty enough to drive them efficiently regardless of the level of digital volume.
My stock MEA rom has a "headset" digital volume value of 60% which gives me a clean sound for my i.e.m's. Whenever I use the 'aux' in on my car I'll change the value to 67%.
I hope this kind of makes sense!

Low AUX Volume (ZE551KL)

I don't know if anyone else has experienced this, but the volume output from the 3.5mm headphone jack is much lower for me than any other phone I've owned. With the volume maxed out, I have to almost crank my car audio volume all the way up to hear songs, and in general, I need to have it at least twice as high as I did with my Galaxy S3 or Droid 4.
I've tried a few volume boosting apps in the Play Store, but none of them made a significant difference. I've also tried messing with every setting in the Audio Manager App, which can make it slightly louder, but also distorts the audio (crackling noises).
I've read that rooting and using a root-specific app of some kind may help the issue, but I don't believe rooting is an option for the ZE551KL yet.
Anyone know a solution that will work?

With earphones working good?

It is less noticeable with headphones, but I haven't used them for an extended period of time. I thought maybe it was my AUX cable, but its the same one I used with my older phones and had no issues.
