All-in-one integrated, 10-15K range, class A/B only

@highend 666. 
Mostly, sound quality is lacking on a video shot. That isn't my point. Perhaps (and I cannot be sure of this) what could be valid is "switching" during the same vid. .

With all the pieces shelved as seen in your Utube vid, I was craving to understand audio differences from all these other pieces.
I think if I still owned my audio salons today, this is what I'd do. Perhaps "differences" would come through helping the customer narrow his decision.
When I was selling, there were 4 other audio stores within a 3 mile radius. 30 manufacturers could be heard with a stroll. That's gone today. Today, I would have to travel 40 miles just to hear some equipment. Add another 150 miles to hear other equipment.
I think this method might be handy-dandy for the consumer to perhaps delineate choices. Then mail-order away to see how it sounds at your place.

@ghasley Consider me a "burbler" of its aesthetics. I know Boulder always attempts to make their designs standout from the rest, looks wise. But their 866 appears to me as an "accordion ". 
Didn't think it was that necessary to do so and strikes me as outlandish.

They have always spent lots of money on their caseworks. Design wise, the shell of the 866 strikes me as an unnecessary stroke and for me, that is not BS. 
I know its me but as good as it may sound to me for that matter, I couldn't own it because I couldn't stand looking at it.

I am surprised no one has mentioned the Constellation series integrated amps.
Purported by some to be one of the finest sounding integrated amps out there. Within your 10-15K criteria.
