Agreed.  There are several bugs being reported in a scattered fashion.  Please use this existing thread so we can communicate them to ibasso:

-I wish the back button on the tough screen was a little larger.

-I'm not as worked up about the variable line out. The volume change happens in the digital domain, and appears to be a lossless process. The variable line out will allow me to match the relative output to the other sources in my system.

-There is a slight improvement in the sound when the DX90 is plugged into a USB battery source, probably due to more on demand current being available (this is just speculative)- but all of the people I played it for with and without the external battery heard the difference. The difference was not as clear when charging via USB wall mounted power source.

-Andy

Here's a couple more thoughts:

-The differences we heard with the battery supply are REAL and consistent. The Mophie juice pack seems to sound the best. Tried with the Eton, and it just wasn't there. A couple of off brand batteries yielded the same result- Mophie sounded the best.

-This player is better than both the x5 and the AK120, mostly because of the amplifier section I suspect, which has way more grunt than anyone would believe given the relatively small size.

-Well recorded FLAC files have a lot more detail in them, and on better recordings the differences between these players shrink a little. The greatest differences can be heard on 16/44 Apple lossless files, which are yielding more detail, depth, separation, and soundstage than on any other portable rig I've ever had/heard.

-This player deserves good headphones- even ones you wouldn't think would make a sensible fiscal match for the $420 dx90. Both my T1 and T5p headphones sound impossibly good on this player, in spite of listing for nearly 3 times it's cost. As I noted earlier this player closes the gap between these two headphones significantly, so if you've been adding the T5p, but need a closed back set of cans, you will not be disappointed- the T5p's sound incredible through this player.

-As a few others have mentioned, the low gain setting seems to be the most neutral, but to some extent this is recording specific. Older, less saturated recordings can be enhanced with the medium gain. Over peaked recordings consistently sound better at the low setting. Experiment!

-I ordered the $25 dollar leather case on ebay- hope its good. I'll keep you posted.

Loving this player. It's allowing me to bring higher sound quality with me to places where I previously felt I had to compromise.

DX90 vs AK 120 and HM-901

I've been doing some heavy comparison between the DX90, the x5, and the AK120,

Check my posts- gotta say, the DX90 is proving its worth, and I feel it is a better player than both. Been demoing with friends and they all seem to felt he same way. I do not have access to the HM I'm afraid, so not able to offer a comparison.

Best,

I use the Fostex TH900 all the time with the DX90. To me, the DX90 is in the same quality sound arena as the TH900. The cost of the DX90 belies what you are getting. If it cost 8 or 9 hundred, I think it might be more in acceptance as to the sound quality. For 419 dollars, well, I think people are getting it at wholesale or less. I think the quality of the sound will hold up for a long time. I also believe this of the DX50, which I still enjoy and awfully lot. Great days for music.

Hmmm can't decide if it's worth it to sell my DX50, and get a DX90.  I'll have to hope I can try it out somewhere before I make a decision.

I'm not surprised, T5P sounds good straight out of DX90 since it's like the closed-back version of T1.

 

DX90 indeed is amazing driving T1. I will have to sell a few more portable amps I have since I'm comfortable enough with DX90 only. I'm not planning to get any cans which are less efficient than T1 anyway.

i took the leap of faith and found it very much worth it! Especially if you dont plan on amping!

post #563 of 3032

Hey guys. Another bug of some sort that i seem to experience (rarely) is that the music will fade out and then fade back in through a period of maybe 2 seconds.

 

Anyone else?

I haven't tried any of the replacement internal batteries yet- all of my experience is other external USB batteries.

I don't know how to aggregate my posts, but the DX90, to my ears anyway, is superior in virtually every way to the AK120, except possibly the resolution of low level detail during quiet passages, which possibly the AK is marginally better. Additionally, the DX90 seems better equipped to handle different types of headphones with different loads than the AK.

I will be borrowing a pair of Audeze closed back phones this coming week- curious to see if this is up to the task....

Long review from Poland - in polish, off course... with comparison to HM 901:

So with the Mophie Juice Pack, you just plug the external battery pack into the usb input on the DX90 and then the DX90 is powered from the external battery pack? I have never used one of these before, but I am open to trying one out if you find the DX90 sounds better with an external battery. This may be a silly question, but do you leave the internal battery in place when using the Mophie?

Yes, just plug in battery as though you were charging the DX90. I've not tried it without the internal battery in place, and I've not tried any of the replacement internal batteries (yet). My issue with replacing the internal battery is using it out of spec- it shouldn't be an issue, but a little voice in my head keeps asking 'what if?'
