On my PM2 with the battery mod Im on 17 hrs of use with Flac and 320 MP3 files and battery is way over 60 %.

Inside the PM2:

I bought a PM2 here on headfi to see if I could replace the PCM1795 with a PCM1792A and possibly upgrade the opamps/caps. First look is promising regarding the DAC (see below) not much info available other than its pin and mode compatible.

Cowon use a modular DAC/AMP design (just not for the end users)

Very interesting is that they are using the Plenue 1 DAC/AMP board but with different Audio Hub, DAC and OPAMP. Also notice the system board is the same as the older Plenue M, so basically they made a new product out of 2 very good older ones and put it in a new case with a new name but for a lower price (lower R&D cost) win win for us.

P1
Audio Hub: WM8998 (incorrect? @Windows X)
DAC: PCM1792A
I/V LPF: OPA1612 x 2
Output/Buffer: OPA1612

PM2
Audio Hub: WM8804
DAC: PCM1795
I/V LPF: OPA1612 x2
Output/Buffer: AD8397

Another newbie question - those components with “S7 Ap” written on top are the capacitors aren’t they? I can’t seem to find what make/model they are.

They are Panasonic Poscap TPE Series Polymer Tantalum (Low ESR)

S7 = 47uF
A = 10v
p = Lot Number

Does it need one ?

Latest fw messed up playlist, sometimes it shows an arrow only, with blank fields. See my previous posts.
