I'll always be different depending on the phones you connect to the DX50. If you want to compare sound signatures from firmware to firmware, use the same cans and connect directly to the HP output, then compare and report. We have to take into consideration your cans and your hearing. wink.gif

As far as the amp, use the same amp on the LO and repeat. biggrin.gif

i totally agree man! and ur sound preference as well above all...:beerchug:

post #9663 of 18426

I am running FItear TG334 directly out HO of the DX50.  EQ OFF..  all running at mid gain and volume 190

 

My rating for the firmwares D- details, L- low, M- Mid, H- High, S- Sound stage,  C- Clarity  

 

1 lowest up to 5 highest..

 

1.2.2 D5, L4, M4, H5, S5, C5

 

1.2.3 D3, L5, M3, H3, S5, C3

 

1.2.5 D4. L3, M4, H4, S5, C4

 

1.2.6 D3, L3, M2, H2, S3, C3

 

1.2.7 D3, L3, M4, H2, S2, C3 

 

 

1.2.2 sound the best but is the most buggy among the above.. Might be too bright for some ppl........ 1.2.6 and 1.2.7 sound the most neutral and boring..

Isn't the TG334 quite sensitive? I use my DN-1000 at 155 on low gain. Isn't the TG334 at 190 in high gain rather loud?

Since which fw?

Don't really remember, sorry… But since quite awhile, as I've been using that functionality since quite a bit :wink_face:

In Regard to Changes in Sound Quality of Firmware Updates

 

So iBasso kindly replied to my email requesting further information on the different sound signatures that we have been discussing here.

If I understand the reply correctly then the differences may not be quite as intended as we thought.

Im still not sure exactly what would entail a change to the 'decoding library' or even what the decoding library is! but I feel much happier having some clarification with the changes. :)

 

Hi,

Thank you for your email.
Did you notice that each time you update the firmware on your other digital audio devices or install a new soundcard driver on your computer, the sound changed?
That is the some reason for why slight changes on the sound signature of the DX50 after firmware update.
We found that each time we made changes on the decoding library, the sound would change slightly.  It isnt like pre-set EQ, which can be customized.
 
Sincerely
post #9667 of 18426

i should just upgrade my dx50 to have a look see on the sound

Thanks Jon exactly what I expected them to say. The only thing they are saying is that when they make software changes to either fix their issues or enhance functionality, that seems to create sound changes, to me it means it's perceived but may not be real. I guess it is up to us to interpret it according to our own experience. wink.gif

The decoding library certainly throws a little mystery though, if they mean reading the audio format and then performing processing on it, I would think that would be material enough to create differences, I wish they would be more explicit about the changes they say they make.

No, you've nailed it. I've been saying much the same thing for the past month or so. Most of what is "wrong" with how DX50 firmware releases sound has more to do with listeners' headphones exaggerating things that their listeners dislike than it does actual changes. That's the only thing that makes any sense given the widely differing "too much X" vs "too much Y" complaints that have arisen with every firmware release after 1.2.2. That's probably tempered with IMO unreasonable expectations that a $240 music player perform like a $10K shelf unit. Perhaps I exaggerate, but then again the claims of huge changes are equally exaggerated. Most of the changes from 1.2.2 through 1.2.7 (ignoring 1.2.3b which is, after all, a beta release) are unnoticeable unless you're specifically looking for them. Funny thing about that is the more you look, the more you find, even when nothing's there.
post #9670 of 18426

jon parker, your previous email made it clear that there is nothing intentional at all in the changes. They are taking the most current decoding algorithms and whatever that does to the sound follows.

 

Now that we have a good bug free firmware, every new firmware will be an adventure to see if we individually prefer what comes down the pipe. I find it quite intriguing.

 

As for switching back to 1.2.2, that was an adventure just to turn the DX50 on. No thanks.

 

One question remains to my mind: where are they getting their decoding algorithms?

If I'm right then they can't because iBasso isn't making those changes. iBasso is using one or more of several open source decoder libraries like libavcodec. They're pulling the library source code changes when they perform firmware or mango builds. It's all automated. They're not looking at the upstream changes. They may even be trying out different libraries; this would explain 1.2.3beta.

What's good about this is they get the latest fixes and improvements. What's bad about this is they get the latest bugs and flaws.

If @jon parker would care to continue the dialog with iBasso, a question to ask is which decoding libraries they're using. If we have that information then we can track upstream changes directly.

Totally agree with you, it would definitively be interesting and nothing better than getting it from the source.
post #9673 of 18426

I would certainly be interested in learning more on this topic

@ratinox - I hear what your saying. I think is fair to state that each headphone will make the iBasso sound 'different' and of course its a big temptation to claim that [with ones own set up] that is how the unit sounds.

But its exactly as you say, there is no -inherently existant from its own side- sound of the unit because everyone's experience / set up / hearing / mood! will effect how it appears to sound.

Im sure we can agree on some general rough points but each person will have different experiences.

 

Anyway I hope I havent come across as trying to portray the changes I personally heard as being huge. In one way I think its fair to say the changes have been quite subtle but perhaps due to having very revealing IEMs plus having the habit of listening in a very concentrated and perhaps critical manner due to my work, (I work in a studio) then some of the changes have been fairly significant for me ...personally!

Im probably making this all seem bigger than it is :D I do love the dx50 100% 

As cooperpwc said - Now that the unit seems to work very well it will be interesting to see what comes now in the future

Thanks Jon for your input, if there is anything you have been is very helpful in getting some of our answers about our hearing obsession, me included, from the DX50 firmware upgrades. I would say keep the good work and continue being curious about anything audio, it is a marvelous world! Getting some inputs from someone who works in a studio is a bonus for us. :beerchug:

I ended up going with EQ on, everything set to 6 on 1.2.7 but I'll say the differences are tiny at best. I'm using the DX50 with the neutral PB2 and the neutral Noble K10 so this might be the reason that the changes don't seem as dramatic to me. If you're going straight from the DX50 into a warm-ish headphone, then adding at bit more warmth from the source might be just that tiny bit too much, making things sound worse? Meh, just a guess. I find the SQ changes to be hardly noticable at all, especially when coming from the DX100. I remember Ibasso making a mistake on the 1.2.3 firmware that screwed the timing of the Sabre DAC, instantly turning all headphones into Beats with muddy boosted bass :D

 

 

Hmm, maybe so.  When I level mine out to all 6's, it sounds 'normal' for my headphones, but normal for my headphones isn't really that nice.  They have quite exaggerated bass and mids, by about 10 db. So at all 6's it's very bassy, and messy sounding.  When I turn the EQ off from the all 6 custom EQ the bass increases even more so.  Although in previous firmwares that didn't have the +-12 steps of EQ, all 6's was the same as the EQ being turned off since it apparently wasn't able to go above 6 before. Now that it can, it seems to float slightly past it when the EQ is turned off.

 

Also in attempt to offset my headphones heavy bass I have a custom EQ set something like this (changed somewhat from previous firmware):

0 -1 -1 3 6 7 7 7

 

I do look forward to what the Kaiser 10 does for me.  :)  Speaking of which, my audiologist actually did have bite blocks.
