I have both X5 and Dx90, I use one for a week then switch. Like described above they both have their strengths. One doesnt have to be better than the other as so many try to pinpoint. Enjoy either .... or both :-)

After extended listen, I don't like either.  I prefer my DIYmod over both, but HDP R10 over the DIYmod.  In terms of resolvability, it's X5, but still lacking something.  DX90's headphone out is not up to snuff IMO, LO is good, but it can be better.

 

In the end, I don't even like the R10 because of it's instability and lack of USB DAC functionality(it would be killer if it had it). With R10's resolvability and and form factor of DX90, and quick touch interface with USB functionality, and I'll be happy with a player that has that balance.  

 

Oh well, maybe Calyx M, but I'm hearing bad ui.  :(  And, I'm not ever going with AK.

I have really been enjoying my new DX90 for the past week. 

 

Coming from an unamped iPod classic 6 gen, the most noticeable thing for me is the added texture, layering and space. I couldn't believe it when I plugged in my ATHM50, because they had almost no sound stage to speak of when using them with an iPod. Totally different headphone on this device! Much more defined bass with a lot of texture, great details on the highs with great seperation and an ample 3D sound stage that adds some much needed sophistication. I'm not sure if it's only the dac at work here or also the added power from the amp section as both of these sections are big improvements over my previous DAP. The M50 are pretty efficient and I find myself between 215-225 on the volume for most of my files (I listen to stuff pretty loud).

 

I mainly purchased the DX90 to use with my Ultrasone Pro 900. I kept reading that to reach their true potential they should be used with an amp. At first I was looking for a portable amp to use with my iPod but then I started reading about all these new hifi daps and decided to get a one box solution. The Pro 900 sound awesome and I feel that the amp brings out more dynamics and quality in the bass than quantity (it's got more than enough anyway!). It adds well defined borders and edges to the sounds coming from the instruments that were otherwise not heard or felt before but are now so apparent. The sound stage and imaging were already good on the Pro 900 through the iPod, but now I can say the stage is even wider with better seperation, although the improvement is not as noticeable as it is on the M50. These are a bit harder to drive and I need to crank up to 230-240 for some files. 

 

The DX90 also arrived with Brainwavz R3 IEM (the newer version - without the memory wire). These are Brainwavz flagship dynamic IEM earphones and I read some reviews and thoughts about them while waiting for them to arrive with the DX90. They sound phenomenal with the DX90 with great seperation, details, and a vast sound stage for their relatively small size. They are more balanced than my over ear headphones with a more neutral presentation, but still sound great with a range of genres like rock,jazz,classical and even some EDM.

 

I'm always using the player on high gain, I feel it always gives me the most dynamic and full sound.

That would be a great question in the 240 thread. Seems a lot of people like it, though at a price.

Nice to read your listening impressions. I look forward to what you think after more hours on the DX90. I was pleasantly surprised after a few hundred hours with even more solid and defined bass and a natural separation of instruments and singers, if recorded that way. Even though I have the Chord Hugo, which is a great sac/amp, I don't miss it when using the DX90. I suspect my DX90 has over 800 hours on it now and I have noticed the positive changes as time goes by.

I'm always using the burn in cable when not in use. Planning to stop at the recommended 400 and then just add the hours to come with listening.

 

I am just wondering how much better the sound could get with a dedicated amp through the LO, even though that would cost more even more money and not really be that portable. I have to force myself to stop reading on these forums haha. Very encouraging to see you mention that you like to use it alone even with the hugo lying around your house :P

 

I also wanted to mention that up until now on my iPod I listened to mostly 320 kbps mp3 files.

 

Now that I had a DAP that can play FLAC as well I had to at least try to see how different it sounds to my mp3 files. I can't really hear any difference, well at least not enough to warrant the much bigger files. I hope I don't get stoned for this around here.

Sorry, agreed, I deleted my post:)  

 

Did you find that the sound through the Hugo also improved with the DX90LO with burn in? Or was it just the HO on the DX90 that improved the most?  I'm just wondering if I should still be burning in my DX90 through the HO with the burn in cable as I've only been using it through the LO>Pure ii or Pico Power for most of its use.

The Sabre sac of the DX90 also uses an opamp, so I would assume that the sound would improve with the LO also. To be honest, I did not think about this comparison as time when on. Also, with the new OEM Samsung batteries, I find the sound to step up another notch, just showing even more of the potential of the DX90 as the power "source" is improved, which seems to be the case with OEM Samsung batteries. With a cost of under 10 dollars on eBay and free shipping, the battery is a very inexpensive and IMO, worthwhile upgrade over the stock battery. The cost being so low and the returns so very good, makes it an almost free upgrade, again, IMO. :^)

I've actually been using the Samsung battery from the beginning, when my DX90 came in I did not realize that the battery for the DX90 was behind the invoice inside the cardboard.  I thought that iBasso forgot to ship that battery with it.  The sad part is that I paid over $70 cad  at the Telus store since I was in such a hurry to get a battery so I could try my DX90.  When I went to throw the box out I double checked and noticed there was a little bulge behind the invoice and I had to cut open the cardboard to get the battery out.  

 

I have been noticing the sound improving in the past week since getting the Pure ii, but this could also be the Pure ii burning in or maybe both. The bass has definitely improved in the past week.  If I had to guess I would think I have around 150-200 hours on the DX90 now.

 

Dave.

Would using DX90 as a DAC consider as a burn in too?

yes but not for the amp section.
post #1498 of 3032
Really? Utilizing the dx90 as a dac bypasses the amp? I must be confused.....
post #1499 of 3032

So it won't exactly consider a burn in since it's not touching the amp... Lol

post #1500 of 3032
When the DX90 is used as a DAC, the headphone amp section is not used, so it is not being burned in.
