Well then.... In lieu of this tragic news, I will look on the bright side... no temptation for an upgrade!
I will be bringing my HD580 with the HD600 grill mod. I would love to compare to two and see if they in fact sound the same as everyone claims. I noticed in your signature, you are considering a Bifrost. We can hook up your A2 and see if that's the direction you'd like to go. Looks like we will be nose deep in Schiit this year .
