My final end game mod to my XE1 (MUSES 2.0 Mod), no more mod for a while. Finished replacing all electrolytic capacitors to Nichicon MUSES range (Fine Gold). Reflow all solder joints under the PCB, seem to have fix the imbalance issue with the preamp knob which I switch with the headphone. Was so excited to get it running, put everything together and realized I forgot to connect the data cable under the PCB. Dohhh.h......h.h....

Yeah thanks for the feedback. I tried to make it neat and clean as possible while maintaining the stock look. Giant caps floating on lead wire just looks so wrong.
20-25 Hours went into reading the thread and learning from what other head fi member already know.
Additional 30 hours researching component size/value/specs to make sure work they well after switching over stock components.
 
12-14 hours to physically do all the modification. Stage in order, thermal pad for power supply, power supply caps, B10K volume switch over, decoupling WIMA caps. Nichicon electrolytic caps. Finalizing decoupling WIMA caps 1800pF/22nF. Reflow PCB and heatsink for DSP.
 
As with impression, only had a quick listen to the LCD3 and & HD800. Still burning in, clarity seem to have improved on the LCD 3. The HD800 sounds a bit warmer than before the mods.

I was watching the WAN show on the Linus tech tips channel on YouTube. They had JJ from Asus as a special guest and he said they were planning a new product to surpass the E1. Didn't give a time frame just said but was in the works

Nice modifications.
 
It would of been nice if you were able to source the WIMA's all in FKP2, but i do know the 8200pF is a tough-y. I think i see a Kemet (sky blue) in there.
The DSP and every other chip does not need a heatsink. I've tested it myself and they run fairly cool.
 
How's the fine gold sound to you?
Do you like it?

I don't consider DSD a upgrade, just a added feature that is more gimmicky than useful, the only true DSD recordings are of live unmixed recordings, as far as I know mixed DSD recordings are PCM mixed before being re-sampled to DSD
