About an hour in I hooked it up direct and so far I believe I prefer it that way. Seemed like everything tightened up and a little more detail. Nothing harsh or digital about it.
Exactly what should happen, more transparent, dynamic, and controlled. Bad recordings maybe less to your liking though.
If any harshness become apparent on good recordings, it’s the fault of the source, amp or speakers, not because your going direct. And that "can" be "band aid" fixed with a preamp in the system that’s less detailed and softens things somewhat.
