There is no comparison in regards to sound quality - RWAK's are a BIG leap in performance from top to bottom!
Any idea what the dual 8741's will do the battery run time....how much more juice to they use vs. stock?
You loose a little because of the extra dac, but it ends up being close to a wash due to not driving the low impedance of headphones in the
case of an RWAK100-S or upcoming RWAK120-S.
With the RWAK100-S, I was able to get over 8-hours of play time with only 24/192k albums on repeat. 16/44.1 gets even better play time (less processing
For fun, I made a battery that has 150% the capacity of the stock one, but it doesn't fit in there unless you don't install the back cover.
If someone can machine a new, deeper back cover, we can probably get a better that has 200% the capacity in there - or things like a high quality stereo potentiometer,
more powerful amp stage, etc. One day if I have the time, I'll look into it....
