Before going balanced on Mjolnir/Gungnir, I would have easily preferred the Annies 90% of the time over the HD650 for classical. However, once balanced... the soundstage change was incredible (could be Mjolnir too)... but ultimately for classical now the HD650 easily wins for any larger orchestral pieces just simply from the sheer soundstage and presence of the concert hall. However, smaller ensemble pieces or piano solos, I like the Annies more.
For acoustic guitars Annies more...
Nearly everything else.... HD650s (on Mojo/Gungnir it's just no contest for most songs compared to Annies on E09K/Gungnir)
