Notred I am curious to hear your impressions after 300+ hours of usage. I am also preferring the BA firmware right now but if this is anything similar to the older unit. The treble will tones down quit a bit and may become boring to you on the BA. We'll see :).
Edit: While I do like the BA firmware I've noticed using the Hiss Adapter on this particular firmware kills the dynamics and the Hiss is still not to my liking so I jumped back to Dynamic. At least on this firmware I can use the impedance adapter and not take away from the dynamics of the player. I'm sure the treble will settle down with usage just as the bass will. This was the case with my previous model so looking forward to the burn in. However I see it possible to opt for a lower impedance adapter and stick with the BA. I'd rather not even go that route since I found something that works already.
