Sorry to hear that.
I run my 100s which are also upgrades to original Walsh 2s off a 60 w/ch Bel Canto c5i imtegrated. 60’watts gets them to a decent volume but not concert level like my other amps with my bigger Ohm Walsh (500 w/ch Bel Canto ref1000m). Its a class d amp which tends to soft clip. Its very possible your amp is clipping also if you are playing very loud. That could explain it but I have had Ohm Walsh now for almost 40 years and have never had any issues even with modest power amps at pretty high volumes.
