One of the best HDMI cable?

It really depends on cable length. For 3-6 feet any decent cable will do. For lengthier ultra HDMI certified (Blue Jeans and others mentioned) will be more solid choice. But from 20 feet and up - no copper wire will push "full 4K resolution", ie. 18Gbps. Only newest active fiber optics cable would work without Metra Gigabit Accelerator
I changed 2 monoprice Redmere and Audioquest Forest cables before I finally got full 4K to my projector via 50 feet HDMI - RUIPRO HDMI Fiber Cable. For more information -avsforum has huge thread dedicated to tests of HDMI cables throughput, guys did an amazing job measuring and comparing, an absolute impossibility in audiophile world.

yes, Belden - get one that is certified for high speed and don't waste $$ on things that don't work

what you may need tho is outstanding HDMI interface - read the white papers for the new Oppo 205 and it's carefully engineered HDMI interface

For Audio, DEFINITELY, Purist Audio Design HDMI.They have a Smooth, Full detailed sound without any brightness or harshness.You cannot go wrong with the Purist

I just bought a previously owned Audioquest Carbon HDMI Cable, 5% silver connectors and controlled for directionality, very high on my list of priorities. 

I bought an Audioquest Carbon 1 meter HDMI for going from my AVR to TV and I can't tell any difference in the picture from the basic cable.
