So W30 arrived.
Will be doing a full comparison review with W3 later but my initial impressions:
2 most important strengths of W30: Stereo Imaging & Refinement across the whole spectrum.
Bass: The bass is very good but more refined than W3 which means I can clearly hear difference between heavy piano keys and drumkits. I can see why many stated bass to be less but its not less, it is more separated and not as one muddy hump. Its def not overpowering...
