What do you mean by "using it any differently"? I was listening at relatively low volume on a rig I always use with them - Schiit Yggdrasil > Warm EQP-WA (Pultec style EQ, retubed) > Schiit Mjolnir 2 > balanced silver cable.5 year warranty even if you bought it second hand, though you do need the original invoice.
Were you using it any differently when the driver failed?
What I did find interesting is the driver that went out, was the one that would break up first if they were ever driven too loudly, which I might add, wasn't tried very often.
