Just an update, rolled in the AD8397 opamp, kept the BUF634P buffer, the sound felt like a total upgrade! The harsh treble associated with the OPA134 and HD600 was totally gone. The AD8397 handled treble sibilant much much better than the OPA134. Bass is a touch less, just a tiny touch, but seems more controlled. But lower-mids seem to be more obvious, which makes the sound warmer. Totally enjoyable, totally awesome!
