The balanced card did drive my RE600 to a very good level, but I prefer using it in unbalanced mode even the RE600 is balanced (w the included unbalance adapter of ourse). I think quite a few other users feel the same with these combo.

Now I'm having the IEM card, I feel the sound is smoother than the balanced card, but I'm using different IEMs now, the K3003i instead. IE800 and RE600 sold already, can't compare directly.

When paired a balanced IEMs or headphones w the balanced card, the sound would have bigger impact, initial feeling would be 'WOW!' But after a while I got tired easily. I still prefer using it in unbalanced mode somehow, which is still quite a big improvement over the standard card. But I only tried RE600 and HD700 with a self made balanced cable.

Actually the power out put from IEM card isn't very weak, it's not as powerful as the balanced card, but it can drive some full sized cans pretty well. I tried T5p and W3000anv with it, they both sound fantastic. It can even push HD800 to a too loud level that I can't bear.

I could only have 5-6 hours play time w the balanced card, and the player got warm pretty fast. With the IEM card, I can easily get 8-9 hours play time, and the player isn't as warm.

Interesting, any experience with minibox card??? I actually just purchased my 901 with iem card

Does anyone know if a full 64GB card freezes when you try to use "all songs" mode?

I have major issues with stuttering with both 128 and 32 cards. The only recommendation I got here was to not play all so songs with shuffle on. Well that did not help. I kept trying different things to stop the stuttering when it starts and as soon as I think I found something that works next time I try it it does not work. My advice is send email to customer service. They need to know about these issues.

Examples of what I thought worked only to find out later that it was maybe just coincidence:

1- Do not play all songs. False
2- Do not use shuffle mode. False
3- Low battery is the issue. False
4- Do reset settings will solve problems. False
5- Power cycle. False
6- Remove and re-insert battery. This I tried last night only to find out this morning that it did not solve today 's stuttering.
7- today I followed remove/insert battery followed by rest settings. It is working now but I am sure at this point it is not a repeatable fix.

And of course I tried different cards and fixing/removing tags. Even tried wav instead of flac.

If this was not a great sounding DAP I would have returned it by now. But I have informed customer service who have been very nice and I am hoping a FW update will fix this issue.

Anyway, u should try another card but if this does not solve your problem make sure to let customer service know.

Did you try reinstall the current firmware? I don't have stuttering on any file or card, so maybe there is a problem with the installation of the firmware/UI.

I did once. I'll try again.

No, I only had the standard, balanced card, and now have the IEM card. Read reviews about the minibox card, seems to be pretty good one. But I'm afraid its output power is too much for IEMs, might end up like the balanced card to me. It's really hard to make an amp which can drive everything nicely, not even for full sized desktop amp unless with some gain settings.

Mini box is better than IEM especially at the highs very obvious. Better details also.

By the way very disappointed with the hifiman 901 that it can't match the old hifiman 801 in the vocal portion. If one is going to use a portable amp I might choose the ak120 or I basso Japan version.

It seemed also their service reply email also very slow. Should reconsider in any new player from them in future.

I think the key difference is that the 801 has a rolled of treble while the 901 is linear. This makes the 801 sound warmer and fuller, but comes at a cost: subjectively less resolution/detail.

That's strange, 901 isn't as colored as 801 but it's still very musical and full. Also you can use the vintage switch to roll off your upper treble a bit.

 

Overall it's a clear step up from 801.

I didn't really follow the 901 closely. Too rich for my blood. But I think that the HD/Vintage switch is just an awesome idea. There are those that love the musicality of the older Hifiman players (I did) and those that wanted full accuracy. The ability to quickly switch it up is brilliant.

Yup, agreed that 901 us a step up but steps down on the vocal portion.

To me for this issue, headphone doesn't do much in this aspect. I have been using same IEM and headphones for years on different DAP.

901 is a step up on vocals too. Although you get the extra lushness and warmth on the vocal on 801, but you lose the sparkle (sibilance etc), air, resolution, ultra detail and smoothness on the vocals. 

 

901 is so far the best DAP for vocals IMO (in ak120, dx100, 801 and 901).

 

But I am not surprised some people just prefer more colored sound, especially when their brains are burn in too much with it.

 

I still remember I had a hard time adjusting when switching from 801 to dx100. But after I could appreciate the neutral and "complete" sound, it's almost impossible to go back. Sadly dx100 has a slight recess in the mid part of the spectrum to achieve its super spacious soundstage and smooth treble. 901 is just better in vocal department.
