"I see the amp is CE certified..."

CE is a "self-certifying" label. Yes, I agree to follow your guidlines/specs/RPs/whatever. No lab, no testing/inspecting of random samples, AFAIK. Not an OSHA approved NRTL (see linky).

"NEC Article 300 Table 310-15(B)(16)"
It's Art 310, Table 310-16 and above for for conductor ampacities.

Emotiva seems confused and the bosses' comments don't help matters. I may have missed it, but I didn't see any power draw numbers in their spec column. ARC also has me confused. It seems all their Reference line of products now have a 20A IEC, regardless of power draw. A dealer told me it was for parts standardization (weak), a tighter connection (possible & probable), and they sound better on a 20A circuit (everything? partial bunk).

In my dream world, and with Powerball winnings, I'd get Neutrik to make a line voltage/amp rated XLR connector for power connections. A mini pin-and-sleeve connector if you will...

"UL says for #2 and smaller wire the 60 degree C column shall be used." Correct, though the text is actually 100A , over and under. #2AWG being the 60C 100A cutoff point where you jump to the 75C column.

This is from ULs "green book", Electrical Construction Materials Directory , Appliance and Utilization Equipment Termination section. Any guidelines in that book are NEC mandatory per NEC 110-3(B).

I've avoided this wire size discussion since the OP omitted one critical fact, and that's the load served size. Length of circuit run is fine, but without a load in amperes, it's (IMO) all guesswork.

Personally, I'd do additional 20A/#12AWG circuits rather than try and bulk up a single one with fence-wire-stiff #10AWG. Unless the residence is a monster McMansion with runs over say,125ft,(just to grab a fast number) and a monster HT setup, I wouldn't see Vd as much of an issue, for small-to-moderate sized 2CH systems. If so, at some rapid point a local sub-panel would be called for.

Sometimes forgotten is the fact that stereo equipment has a specified operating voltage spread. It's not going to sound bad because you have 119VAC at the outlet, nor better if you have 121VAC.
