Thanks to COVID19, I have so much time on my hands. Swapped out those tiny battery wires on my 1A with 22 awg OCC. Five solid core wires are hard to bent so be extra careful if someone think about of doing this. Did the same with the S-Master active ground wire since it's just one wire on the back side of the board.

What a dramatic change overall. Stock 3.02 is now as good as D1.02 i try last week. At the moment, J + Ultimate 1.02 w/Tone Control 0,0,0 is a good combo for me.

Quite a bit more extension throughout the range. Dynamic range, and resolution are just amazing. Seem like I'm gaining 30% more information from 25dB and lower.

It's startling. I am not exaggerating When I say this modded 1A is in the same league as my Benchmark DAC3, and beats it in some ways.
That is quite a statement, but it's true in this case.
Really looking forward to finishing it off with some high end capacitors, I don't think another stock DAP will touch this for a long time to come.

Did you have to disassemble a lot of stuff to get to the back? Is it relatively easy to get to?

Thanks to @proedros that I could get the Jupiter for 3.01
It reminds of DMP-Z1 1.02

Yes, take a look at Service manual. Or take a look how @Whitigir did it Here
If too hard, let K-Mod do it professionally but that come with premium pricetag.

So I recently rolled to J1 3.01 with J region. You guys weren't kidding about it being smooth and relaxed (also powerful! Had to dial back on the volume because it was too loud lol!) Thanks for yet another compelling fw @Whitigir and thanks for the super detailed write up on the differences in the regions @Midnstorms!

Jupiter T1 for 3.01 region E2 lovely sound

 

[NickleCo]

This album with J region and 3.01J1 feels so realistic. Timbre is just on point really justifies the atlas' signature. Especially on this album.

 

[RobertP]

Firmwares are like meats and regions are like salt and piper.

I'm listening to 60's songs at the moment. Never thought these records are better than some newer recordings.

Same thoughts, could never stand to listen to this album before.

Nice records!

 

[gerelmx1986]

Nice records!

These specific one is from 1959, sounds awesome, Phillip's certainly didn't do a good job with the remastering to CD (less bass texture, artificially boosted highs. I have the vinyl RIP in 24/96, bass response is better as well more natural trebles)

No matter how good our Walkman is at reproducing sound when you take something smooth and make it not smooth (A to D conversion) you arent getting an optimal transfer of information

Technically true. The question is to what extent that non optimal is audible though. To some it will be sometimes but to most it probably won’t be

We will eventually get there. Digital music still has a long way to go
