  Ok, I updated the github description Does it sound different to SU1.2.4 ? Thx.

Actually, I'm hearing more clarity and detail with some tracks than before.  "Alt-J - Fitzpleasure" and "Passion Pit - Swimming In The Flood" are two songs I noticed the improvements in.  The one song I usually demo with is "Angus and Julia Stone - Silver Coins".  One thing I noticed is, the instruments in the song are better defined.  I can hear instruments in the background a little better than before.  I believe the sound is little bright, but I enjoy it.  FLAC is enabled, IRR is enabled, Sharp Roll-Off is selected, and the amp is set to low gain.

I agree, "flac only" is more bright, not so punchy/active but it's more smooth.
Anyway you can choose any mode

I use the same configuration and the SQ is awesome.

Keep in mind I'm using low impedance IEMs, hence the low gain.  When I set the amp to medium gain it seemed like the volume would go up in all areas, except for the vocals.  I'll try to demo with my Q701 and M50x when I get home tonight.

I totally agree.

But guys, please try FLAC-Only mode + IRR OFF + DF Slow roll-off + amp @ mid gain also. For me personally I find IRR ON making whole spectrum littlebit too "harsh" and it seems to have less depth in soundstage towards middle-front (more width emphasized soundstage), loses tinybit in bass/kick quantity, less spread out and separated instruments/sounds (depth towards front & back). IRR ON is NOT bad though and has its good things going on but for me it seems to say secretly at background "I`m trying to be analytical for You but please don`t forget to enjoy music". This impression seems to go for all cans I own but Fidelio X1`s bring it out most, probably because it has very good large airy soundstage and depth towards front.
 
Now, this is subjective opinion but I find this SU setup described above THE BEST sound I have ever heard with my Fidelio X1 yet.
I found myself yesterday listening music for a long time late at night (technically morning, before workday btw lol) and I just wanted to listen more and more. For example I was totally blown away how A Perfect Circle - eMotion album sounded and those amazing background sounds and detail retrieval, separation and transparency going on. It`s not overly analiytical or overly lush/fun sounding - it`s something in between and I have not experienced this kind of synergy before. I was actually starting to doubt if they were just my emotions regarding this album but no, DX50 + Fidelio X1 seems to be PERFECT match. Honestly, I`m blown away by this DAP with this firmware & settings...

Took another pic in normal daylight:

 
edit: NB! Those who don`t know - to select lossless only or irr off/on - You must switch DX50 to LOCK and then turn it on while LOCK is ON. After
selecting desired options just turn LOCK OFF.

Nice stand

 
This is YOURS now!   You`ve earned it because of Your SU firmware tweaking (I hope You`ll keep it up) and the thing it did with my setup! Will post it soon...

  I'm just confused on if the DX50 is paired with a DAC/Amp, then the internal ones will be bypassed, then doesn't it kind of make buying the DX50 meaningless?

Also, what good amp pairings are there with the DX50?

You plug the DX50 into the amp using Line Out, not Headphone Out.  It bypasses the internal amp.  And no, it just makes the DX50 better.  You can amp an iPod for the same reason.  The JDS C5 is very good, some folks use the C&C BH ($100), there are a bunch of others.  
 
The amp in the DX90 is supposed to be better, I have no experience with it so look at the DX90 threads to see how happy people are with it.
 
I already had an amp from a previous setup, so plugged it in to the DX50 and it was glorious.  You might be totally happy with the DX50 by itself.  Only way to know is to try, unfortunately.  
 
The C5D will allow you to play your music through a computer using USB.  The C5 is just an amp, it will not allow you to do so.  
 
iBasso has released drivers for Windows that for some people with some configurations allows them to play their music through the USB connection.  You would NOT need an amp if that worked for you that way.

I gave this a try with my IEMs and I found with IRR OFF, the vocals weren't as good with some stuff I listened to.  With IRR ON, the back up vocals are noticeable.  Which IRR OFF, I can hear the back up vocals, but not as clearly... seems like they aren't as clearly defined.

Sounds like IEM soundstage limitation. You used mid gain? I use also mid gain with my IEM`s (16Ohm) and far better than @ low gain. 
Of course this is just my subjective opinion about irr on/off and goes for my cans and setup. That`s the thing - this IRR ON setting is good enhancement for cans/IEM`s with not so large soundstage (brings middle part of soundstage closer and more into focus) and definitely suits for many users better, depending on cans, music, taste etc.
 
Edit: btw, I found cool wallpaper that goes well with sound unlocked fw (I feel like fanclub member already lol) ;D

Just to clarify, you have the VSD1 not the VSD1S IEMs right?  How are the GR07be IEMs better than the VSD1?  Are the GR07be worth more than double the price?  I'm not looking for something bassy, hence why I went with the VSD1S.  Just got my Q701s in the mail today, and I love how they sound so far.  If the VSD1S can sound somewhat similar to the Q701s, I'll be happy.

I never had the VSD1, I did have the VSD1s and I liked them a lot but there just not as full as the GR07be. If your not a bass head than there probably not for you. I have listened to a lot of different IEMs and these have been my favorite so far. The bass is hard hitting and clean and it goes way down, the mids are up front but the highs are not as clean and fluent as the VSD1s which to is the only thing they excell at.
Are they worth the 130.00 dollars more, probably not. I do want to try other new line that just came out though. YMMV

Okay.  I tried posting in a new thread and received one reply which didn't seem to fix my problem so I'm posting on the main dx50 thread in hopes of answering this.
 
the question involves using AIFF files on the DX50.  I can't seem to get the album art to show [or the genre metatag to read].  I assume this info is somewhere in this thread but I can't seem to find it with the search function - sorry.  I am ripping with XLD.
 
Can anyone help or point me in the right direction?  How do you get AIFF album art to show on this device? And, is the DX50 reading the metadata off the AIFF files? If it isn't supported then that's good to know as well.
 
The older I get the stupider I feel.
 
Thanks
 
David

 

[olddude]

Are you locked into AIFF?  I use XLD and have it convert to FLAC and art shows up fine.  Do you have the box checked to embed cover art in files in XLD>Preferences>Metadata?
 
I'm gonna rip an album to AIFF right now and see if it works.  I'll post back in a minute (well, 5)

 

[olddude]

I changed my ripping prefs to AIFF and ripped the first cut of Sticky Fingers/Rolling Stones.  Put it in my card and opened it up.  No art.  So.... maybe AIFF won't work with cover art.  
 
XLD will do FLAC w/art, no issues.

 

[Monday]

Thanks Olddude.  I'm re-ripping a library and although I know FLAC is basically as good as AIFF I just want to skip any compression  whatsoever. I want to do one rip that will satisfy me on my reference system as well as my portable.  And now that drive space is not really an issue - why not?  thanks for doing the test.  
 
Oh, and yes the box is checked.
 
Thanks again.

AIFF is basically WAV but with an apple stink, and WAV doesn't support cover art either as far as I know

Thanks for the detailed reply, motivates me to go get a DX50, maybe second hand for $130-140, and maybe an amp as well. From what I understand, it means that with the new iBasso driver, I'd be able to connect from computer to the DX50, then to an amp, then to my headphones? I guess that means two interconnect cables.
