I've been working on a line level amp board that bypasses the headphone amp (CXA1034P), and delivers proper line level audio from the Genesis mix circuits. The result is a much clearer, more full-frequency response. Note that this mod is different from the YM3438 piggy-back mod you may have heard about. That mod changes the sound considerably, whereas my mod just makes the original audio more clear. Pic of the prototype board below:
And here's a selection of some of my favorite Genesis tracks recorded with the same Genesis. One set of tracks is purely stock headphone amp, while the other set is from my line level amp. The equipment used was exactly the same for each set of recordings, and at the exact same volume levels:

Board design is still in prototype phase, but will be ready some time next month. I have to design a secondary smaller board with a sliding SMD toggle switch that will allow users to simply flick the switch between line level amp and original CXA headphone amp (as both amps cannot run from the same inputs at the same time).
