Welp... Figure I'll post another update now that I'm at the 100hr or so mark.
The speakers have started to fill out quite a bit more now in terms of soundstage density,width and depth. The sound is much more "detached" from the cabinet now then it was in prior hours of use.
The center image is very strong and focused now and bass has started to make itself more known on familiar tracks. These things are Fast!
I've already caught myself forgetting that I'm listening to a box speaker and remain fully occupied and entertained by the new details present throughout the soundstage.
Human voices both Male and Female continue to impress me with their realistic sense of thereness and I'm confident that this aspect of the speakers character will not get old for a very long time.
Lastly, I continue to find myself wanting to bury the volume knob on the PreAmp (even though I have not done so) due to how clean and clear everything sounds. Absolutely zero hash, harshness or fatigue to report thus far.
Man I'm liking these bad boys
More to come later
