Hi @veerossi
i found the Baseline Blue cables to be fine for sub high level connections. I have nice cables everywhere, but do find the sub cables the least impactful. I certainly looked at other options, but I have one long run of 30’ under the floor and across the room, and never felt the need to upgrade more. I am sure you can make better cables with nice copper wire. Understand your connections first as you may likely only need two wires vs the three in a REL wire.
