It might be helpful if you describe your setup (amp, speakers, etc), as well as what styles/sounds you're into. Also, can you further describe the edginess? Is it undesirable?

The L90s are definitely refined and very versatile. The "standard set" is 4H and 6H, which might help you get a little more variation from the 9.2H 500XL while sounding very warm and powerful. I wouldn't want to unconditionally recommend them, no matter how tempting
