So I finished my first cmoy and it sounds pretty good! When I try it loud (pot about halfway maybe), the bass seems to level out and everything starts to distort. I know it's not the headphones (ATH M50) because they crank as loud with my fiio e5 without distorting. I'm guessing (I have no clue) that it is due to the TLE2426's inability to keep things stable at higher currents? Maybe this is normal...Or maybe something else?
Here are some details on my cmoy:
Radio Shack board
Gain of 6
TLE2426 3 pin
Single 470uf PS cap (per tangent's recommendation)
1uf input caps
9V battery powered
I can't go to 18v due to my enclosure size...I already had to modify the layout to get it all to fit.
I know there is the possibility of putting caps on the output of the rail splitter. I have 2 questions about this:
1) Will adding 2 220uf caps to the rail splitter's output help with distortion?
2) Will it matter if I leave my 470uf cap out in front of the rail splitter (while simultaneously using caps on the output)?
Any other ideas?
