One of the best HDMI cable?

I faced the same questions about 5 years ago when I tried a Mapleshade ViviLink cable for about $165.  I had a couple of PS-Audio's I2s all-silver HDMI cables that retailed for around $1k/meter and it was no contest.  I recently moved and needed to combine my HT and stereo systems in one room.  The main HDMI cable is the run from LG OLED tv to the Yamaha receiver that is in place as a DAC and HDMI switching role.  I also have one to connect an OPPO 95 dedicated to Blue rays.  The rest of the system is far more refined since the last time I tested these HDMIs against each other.  

Mapleshade's wires are a little flimsy and are VERY directional, but they are still the best I have seen in my own system.

Belden=sending all the right signals.
They count more real engineers than all the high-end wanabees combined.  They have theor products used in the most demanding applications... Tv studios, live concerts, recording studios, you name it, and if they were bad, we would see and hear it.

For 4k the quality of hdmi does matter: http://archimago.blogspot.nl/2017/01/quickie-post-yes-cables-matters-for.html

Don't look now, but there is a new and improved HDMI cable that is 2.1 !   If you care to, you can  read an article from Dec. 4, 2017 from TechHive entitled "2.1 HDMI specs and features : Everything you need to know."

I have been through a dozen high end HDMI cables, purely for Videophile useage, not audio. Most made no difference. Some expensive cables were worse than stock (Chord HDMI Active, i'm looking at you).

But the best was the Mapleshade Vivlink 2 with Plus Upgrade. And its affordable. Only negative is Mapleshades usual ridiculous construction technique, but that is a necessary part of their performance.
