I think that Angela Cardas believes -- in her own home system -- that the Clear Reflection is a bit smoother than the Clear Beyond. The Pendragon panels don't need any assistance in the resolution or transparency departments.
Despite many members disagreeing I was not comfortable considering sound changes from swapping 1m interconnects between front-end components as being predictive of what changes to the 47' interconnect run would sound like.
So I had to make an Internet-researched guess.
Sibilance is definitely lower. I hear the change as a more balanced presentation, meaning a preferable tonal balance that does not draw my attention to treble frequencies.
Putting it differently, can't I just be happy with the sound now?
