I found that the M30 Lyre (Traditional Beak) was better than the 5RV Lyre in terms of clarity of tone and dynamic range

Not as big a sound, but more homogeneous across registers, easier to control, I have a greater range of dynamics, feel really good about my articulation, my altissimo is much easier and sounds nicer

Just enhanced my daughters high and low range

My clarion and altissimo range sounds so much better, as well as the A
