Going to order some OPA2111KP's. They are listed as "recommended" on the Asus manual.
From what I've read they seem to have a really good bass, soundstage and a somewhat lower treble - which is exactly what I'm looking for.
Does anyone already had the chance to try them out?
Update: Also going to check out the OPA2227's
