Another option between the Chocolate & the Vodka level, would be the Carbon. I recently installed one from my Blueray (OPPO BDP-95) to tv. I replaced a Monster M1000 that I've head for ~5yrs (was their top of the line). They are a short run (~6 & 8 ft) & I know some claim a difference between HDMI while others say there is absolutly none (being a digital cable, unless running long lengths) but without going back & forth I think I did experience a difference. Colours seemed abit different (possibly more natural) & the blacks got blacker. I did need to re-calibrate for black levels after the swap, so I don't think the difference was, all in my head.
Makes sense to me, what your dealer recommended. Go with different cable "levels" based on how critical the connection is. I'll probably go with the Chocolate from my satellite to tv.
