DX200/220 Amp8, MAX and other EX modifications

[behemothkat]

I am awaiting for @Nayparm to finish his builds and then modified AndroidOS or possibly MangoOS to further be taking advantage of the player

If not a secret, to which directions for OS optimization will you research?

I can’t speak for it as @Nayparm will be leading this project

I can tag @hshock76 for a references point view

He has DAC DX220 Stock

He also has DAC Dx220EX

He also has Amp8EX

He also has Amp8EX Final (this is the final tweaks and upgrades to further experiments and a collective tuning to do MAX justices). This version has never and will not be published

Anyways, What I would like for him to confirm in here is how important the main body or the main DAC of DX220 can benefit from the EX modifications

Please note that MAX is very good, the AMP section is hugely improved Amp7 and Amp8 all in one with upgraded capacitors and designs architecture together with the improved power rails from it independent batteries, and it isn’t necessary to modify the AMPMAX. But definitely the main DAC would need it

Then again, we all have very different point of views, experiences and preferences

Here's a quick low down on the modded DX220EX and Amp8EX Ver2.0:

DAC DX220EX w/ Amp8EX vs Stock DX220 w/ Amp8EX -
Modded main unit adds more air, expands sound stage and fills up all the voids in the sound stage. There is a very strong sense of presence and ambiance and you get the feeling of attending a "live" performance.

DAC DX220EX w/ Amp8EX Ver 2.0 vs DAC DX220EX w/ Amp8EX -
The Ver2.0 of Amp8EX adds further weight and density to mids and bass which gives a fuller sound and works great for vocal focused genres.

In short, modded main player with ver2.0 Amp8EX is a significant step up from stock player and Amp8EX and that is why I am so hyped up about MAX-EX as according to @Whitigir, it exceeds the performance of full blow DX220EX+Amp8EX Ver2.0.

Moded my amp1 mk2 yesterday. It does not look clean, sorry for that. Was intended as just a test run. But it will now stay like this for home speaker/desktop listening. Ended up hot glueing together. Fantastic results. Thank you for the inspiration @Nayparm @Whitigir. Your the best.

Project update. Amazing combo.

You must have some unusual pockets to carry that bad boy in!

[Whitigir]

I agree and holy cow

What does those big caps do?

Thx. But no thats just for home use. Sounds so good. That i am already considering, to modify the back cover on my amp8, by cutting out some holes for one cerafine 1000uf and those 4 audio note kasei caps. Though not quite sure if anythings needs to be modified for them to fit inside, 100uf16v are 6.3mm diameter. Seems like it might just fit.
Already itching to order 50uf16v ones for amp 8 and use one cerafine combined with one audio note for power. Though they are not cheap. Also need to get my hands on a smal flex or something to cut the back cover.

Power smothing and guess signature tuning. Atleast thats what it sounds like. Had tried silmics 2 there, but it lacked the peaks, was to smooth. Cerafines sound better all around in this aplication, more natural.

Actually I would suggest creating a custom faceplate for the back for those huge caps and eventually you can rest the whole dap on a desk using the amp!

Thats a great idea. Had an similar idea like that aswell, but never followed up on checking the price for machining such a thing. Would make it just 1cm higher than stock one. 3d printing would be an option though. But would preffer metal one.

Yep that would look nice! Keep us posted if you do !

The only way to make a metal one is to CNC it out, but that probably is going to be expensive

Tbh am cosidering of saving money for cnc whole chassis from copper. Would look fantastic. Found a company in us that could do smal runs of 1. But rather get it made here in germany(will cost more). But what worries me is the tollernces.
