These units are supplied with a 'generic' Korean-manufactured HDMI cable that outperforms every audiophile HDMI cable we have experienced to date!  Korean engineering is now world-renowned and these cables command my respect!
 
The video image and sound presentation are immersive.  Unfortunately, using digital film equipment - capturing the benefit remains illusive.  We are offering 30 day moneyback guarantee when payment (check or electronic) is without associated fees.
