My Ak300 stuck in bootloop. Firmware can't be dowload from Website. Anybody has any clue on how to restore/re-flash the firmware?

This amp This amp really does need some tuning and once you play around with the 4 resistors (if you don't know what you are doing like me), it nearly impossible to get it right. The seller advised me to play around with the transitor to counter channel imbalance then it really difficult to...

The amp sound nice but cannot use as amp only. The Dac chip a bit outdated comparing to dual Dac chip DAP nowadays.

My V90-BHA produce hissing noise even with volume at 0. Touch the unit, the hissing reduce a little bit but not totally. Really annoying. The sound is great but the hiss ruined everything.

Thanks WitzyZed. I might try to switch back to original ROM. The UI responsiveness is definitely an issue. I just want it to run as smooth as possible, no need for streaming. Right now, it much slower than my Iphone 4 connect to a DAC.

Firstly, Thanks to all the developers who actually spent the time trying to give X5iii some more juice. I am having: - Kernel 3.0.101+ #34 Build: 1.2.5 fidelizer Playing through Onkyo HF player. But the speed is not very impressive. Crash alot. Any recommendations? Which combinations are...

I actually had ask a friend to made a Male MiniXLR to 2.5mm jack for the MF200b. But have to be honest, not my cup of tea.

Having the combo MF200B + V90HBA. The sound is very bright and can be quite harsh, with lots of background noise when not playing. Connected via RCA from line-out from my Fiio X5iii The headphone is not very comfortable. The amp is very light, feel kinda cheap even though the finishing is good...

If you are not careful when adjusting the resistors, the sound will be messed up with heavy distortion. This amp more recommend for earbuds not IEMs.

Rsa male is too fragile. Broke couple of them already. It really dificult for soldering as well. Plastic is quite tricky if the heat too hot

Not sure if anybody still using this. My Typhoon keep blinking red light when use with Iphone as Dac/amp or green for very brief period. Work fine if use only as Amp.

Mine B4X also experiencing channel imbalance. But after 10mins playing, it balanced again.
