I'm looking forward to an answer on this question too. I hope Paul will ask technicians about battery life considering constant charging.  

I wonder if ibasso intends to create a balanced XLR cable for balanced amps. Like the one that thebit has done. If i understand correctly they use 3.5mm (unbalanced+lineout combined) as a ground. I suppose such cable could be a great option for audiophiles interested in almost full time usage of...

I wish someone could compare plain DX80 with DX200 in order to determine if the upgrade is really substantial. For instance, what about overall sounds density/sturdiness and quantity of mid/upper bass range? Does DX200 make dynamic music, like EDM n trip-hop, perceived in the right expressive...

Indeed. But i think it's also about light refraction. I dont like the fact that its leather case is brown. I'd prefer the common color... Much more suitable. 

  Click ME   HE-6 - 83.5dB (so they need about 1500 mw at 50ohm) HD800s - 102dB (20mw at 300ohm) HD650 - 103dB (16mw at 300ohm)

It will for sure, but my point is: or ibasso makes just one version (as they declared dx200 with 64gb and 1 uSD slot), or they present all versions at once at the very beginning of its realization for people to choose the right one from the start and not to 'read fortune' will they offer bigger...

Ofc all of you talking about 512/256gb of internal storage in a 'later dx200 'pro' version' dont consider how ibasso would be judged by those who bought 'standard' 64gb version earlier. Do you want to see how 'poor simpletons' riding in the 'hype train' will provide primary ROI to iBasso...

  We all will forgive this unpleasantness to them, when we'll be sure that dx200 destroys its competitors in terms of SQ and overall usability.

DX80 is almost dead silent with my ue900 which are 30ohm. It only hisses when i change volume. As far as i know shure 846 are 9ohm. DX80 has <0.1ohm output impendance, which means that it theoretically produces zero hiss with all iems. My first DX80 produced much louder hiss noise, than my...

I've compared with Asus Xonar ST/STX stock and internal Jotunheim's DAC. Yep, both are cheap entry level DACs. In comparison Xonar has inanimate in-your-face sound with narrower SS, bloated wide less-controlled mid-upper bass (sub-bass punches equally) and not so sharp transients. Sound is not...

I agree with everything, but i find DX80's bass via line out exaggerated a bit but not bloated at all. Its very nice controlled, thick, perfect quantity of mid-upper bass for dance/dynamic music, so it makes it to sound full of energy/assertiveness. Maybe you've considered it bloated because of...

IMHO, DT-1770 - upgraded MSR7 in terms of ALL qualities and completely worth of additional $. a990z is a little better than MSR7, but usable only at home (MSR7 obviously suits for portable use). DT1770 doesnt have lot more bass quantity, its just better contolled and more holistic. Mids of 1770s...

As i'd love to see Focal EleaXX for like 500$ too 

I've A/B them and my conclusions are (Cayin compared to DX80): 1) More airy sound 2) Recessed low freqs 3) Less dynamic 4) Less analitycal 5) Better mids - they sign very nice 6) Better musicality  7) Highs have softer reverberations Overall DX80 has more in your face, dynamic, forceful...

So, do u still use dt1770 or did u forget them like a bad dream with all its plastic resonances after purchasing the 1990?  Lots of reviews about 1990's overall superiority over 1770. I feel deceived by Beyers  . A lil bit...

Same here! Try to touch the chassis and headphones adapter at the same time (in my case this removes the hiss:) ). Actually, sometimes this issue irritates me a little...

I pair DX80 with UE900. First DX80 had some hiss sound when i changed volume. It had consumption problems and i changed it. Second DX80 has no issues with hissing at all (completely black background) as in specs DX80 has output impendance <0.1ohm. But after 3 month of use i have consumption...

I dont have any purpose to remember such things. I just rely on my hearing. I have another things to spend money on, but i know that i've spent my 50$ on AQ carbon for audible effect. The most revealing was QED Reference, but highs became too sharp for me as i listen to EDM mostly. BTW I tested...

What if i tell you that i dont have to discuss this subject with person who havent ever compared cheap and expensive usb cables with non-galvanic isolated usb and has opinion with no practice? Its like not to believe that frequent consuming processed red meat speeds-up cancer cells synthesis...

Excellent dacs are at least Auralic Vega, Schiit Gumby/Yggy, Rockna Wavedream, Chord HugoTT/Dave, MSB, Audio Note and etc. This internal Jodies DAC is more for convinience, but not for frequent goose bumps :) Its not very good because its tonality is cold and overall sound signature is...

i dont think so - this device is too simple to provide some serious effect.  Get normal/good cable to use it with internal Jodies DAC - it's the best choice. After u upgrade your DAC to 500-2000$ one, like Gungnir Multibit for example, its worth to get something like uptone regen, intona usb...

it does benefit when u plug good usb cable in schitty usb source like laptop/pc w/o galvanic isolation. Go for used AQ carbon - its rly musical one. WW Ultraviolet 7 is mediocre. I feel like AQ Cinnamon is better. Dont go for ADl Formula 2 - fail. Furutech GT2 is good only and worth it. AQ...

http://www.head-fi.org/t/814629/beyerdynamic-dt-1990-pro-beyers-open-back-mastering-headphone/435#post_12978981   You decide which one to buy. 200$ for 6xx is like 400-450$ for 1770/1990 imho. I'll go for 6xx as i already have 1770 akin to 1990. Jodie is a must at 400$ for both HPs. Internal...

1. 40$. Standard surge protector 2. 40$-AQ Forest USB. 60$-Good XLR cables from DAC to Jodie.  3. 200$. Uptone regen to clear schitty laptop/pc usb. 4. 700-900$ Used good R2R/Multibit DAC. 5. 400$. Jodie 6. 500$. A-T MSR7/a990z/1000x/z or Beyer DT880/DT1770/DT1990, or Sennh 600/650 or add...

After i charge to 100% and leave it 'off' for one-two days - i find my DX80 with 70-80% and need to charge it again. I tested how long this dap out of the box can play flac with my UE900 - 10.5 hours. Now its only 7 hours. 3 months of use. Maybe this is due to using DX80 as a PC DAC, because...
