FIRMWARE BUG: The sound becomes worse at low battery level. Stock firmware 1.2.8. No problem with Rockbox.

I've noticed this too. Reason why I always bring my spare batts.
Is iBasso currently working on a firmware update for the dx50? I'm just curious.

You can start with the OPamps and extra buffers that came the PB2. There is a a manual on the ibasso website that shows you how to change them.
You can also look at this thread which will give you more background information :

When connecting using DB2, it logical to run a full balance system with portable amp like PB2, RSA intruder, Duet, etc
The benefit is quite immediate felt as you hear better soundstage, instrument separation and fuller sound.
I am sure how much that improvement is attributed to DB2 specifically and whether to SQ improvement justifies carrying a 3piece stack is up to each individual....
Its the same reason why DX90 looks promising with its dual DAC design...
So yeah I am really enjoying my new amp but I am abit confused with the balance input, so the guy told me that unless my headphone uses a balance connector then it's pointless to use a balance cable between my PB 2 and DB2( which i will get in the future) My question is that I've seen someone saying they use the HD 650 balance connector to the DX 50 and PB 2 but the HD 650 I saw doesn't have a balance connector, do i have to buy one?
The shop guy told me that 6-pin balance connector are rare and hard to find, also i am wondering if I had a balance cable between my PB2 and DP2 if it's gonna sound better even if the output connector to my headphone is still unbalance. One last question is will it sound better if I use my cheap hippo amp as a preamp to my PB2 then Dx50? I just tried it and it works but I am hoping for someone to tell me if it will diminish the sound or improve it.
Sorry one more question, can someone explain to me more in detail with OPamp chips that came with the PB2? I just need to know which Opamp give wat kinda sound.

Hello there,
I posted this in the 'ask for a recommendation' section but I thought I may have some luck here...
I have a DX50 and a pair of HD598's. I've been somewhat disappointed with the sound but recently I ran it through my 17 year old Audiolab 8000A and suddenly everything makes sense! The 598's are really singing now!
The sound is so much more fuller and really gives the phones the oomph they need. I particularly like the deep sub bass, and the tightness and control across the instruments and the lovely sense of space and timing. It really has the Wow factor for me. But of course an 8000A is hardly portable!
So how much would I need to spend in order to get a comparable sound? Can anyone recommend a particular amp that they would consider to be similar in sound to the Audiolab or have ideas what amp would give the sound I am looking for?
Thank you
