Best of all:
2 dedicated audio lines with hospital grade outlets and 10 gauge wire. Was not expecting it to make a big difference...and it wasn't...but it wasn't a small difference either. It was a solid upgrade.
I had ordered a new tube amp when the lines were put in and I almost wanted to cancel.
I had a Carver with great high end but weak bass...and the bass was now sublime...overall sound was more focused.
