After reading the original post I was curious as to whether or not a power cable change on y REL T/7x would result in any improvements.
After having a positive experience with Zavfino Prima speaker cables, I got in touch with Raymond at Zavfino and ordered a Fina like gladmo did.
I'll be damned if it did not improve the texture and extension. Bass seems to stop and stop faster and sounds very real in my system with my ears.
Thanks gladmo for the insight.
