Hi Defour,
We like #74 best, could you try maybe reversing the logo and putting the ear somehow on the left instead of the right... so maybe the ear is part of H somehow? We like the angle of the text currently, can you please make the text below follow suit with italic like the font above it? Also a different font would be preferred for the words "Harmonic Looping Systems". something less robotic looking more clean please.
Thanks!
