DX200/220 Amp8, MAX and other EX modifications

[Whitigir]

The front side capacitors and back side are parallel, therefore just short it on the front side.
The wire is silvered copper. And the best signature is clear full bass sound with excellent resolution

Glad to see diversity of AMP8 iteration models~ Try different recipes and share your own opinion on your works~~

Idk, you try it and share with us ? Modification is all about personal experiments next to theory . I normally am only motivated when there is something I am not happy with. ATM, I love how the EX sounds with HD800S

Simple and cheapest mod

Dear friends,
the best mod of ALL ibasso amps with the best sound is ->


just try to remove (short-circuit) decoupling caps and you'll be very surprised of the sound changes

@plutonim
Interesting mod. I'm just wondering why and how this shortcuts improve the sound. What is the purpose of the capacitors that were shortcutted?
The circuit designer/engineer must have included them for a good reason, or what do you think?
Could you provide more informationen about this?

Had a failed AMP8W mod sent to me along with a new AMP8 to do an AMP8EX-P V2 mod. Apparently the botched mod was performed by a pro technician.

The board wasn't pretty and some attempt to repair looks to have been made for damaged pads and vias.



Ended up doing a full Nichicon KW mod, with the largest physical size cap i've managed to fit in an AMP8 (v1-3), I found 1 possible position for the Nichicon KW 1000uF 16v Then after cleaning and repairing the damaged area fitted 4 x KW 220uF 16v (ditched the burnt tants)

Burning this in as I type/listen. I'm very impressed how it's evolving. Authorative bass, smooth highs, nice pair with dx150 AK4490 dacs, can't test with ESS9028Pro dacs

I have had look, may look at optimizing android more and larger capacity battery in one.
Want to transpose your EX mod to a DX150 along with the AK4493 dac upgrade I did on one a good while back too.
