Yes, the difference between them is rather large. I also compared both sets (excluding the power cables) in my system, and felt the same as you, but I was not prepared to spend such a large amount in cables. Recently I heard about a Devialet / Wislon Sasha owner who bought a complete set of Odin cables after trying them for a few days!
Hi Microstrip. I own the Valhalla digicable which I really liked a lot when I compared it with TA Ref digicable. Otherwise, my signal and speaker cables are TA RefMM/XL. Since I have comparatively less experience with Valhalla, and none with Odin, how do you compare TA Opus/MM with Odin/Valhalla? Thanks for any guidance. Not looking to change...just looking to learn.
