I like it when a manufacturer executes, takes some chances, innovates and achieves their design goals. The sound quality, check. Versatility and content, check. Angled front and user interface, check.

The heatsinks actually work extremely well, they aren't fragile in the least nor prone to bending like so many designs. They are sturdy and and actually are very convenient when lifting/moving the amplifier.  They provide a wonderful non slip way for the finger to grip while placing the 866. They are not, however, capable of slicing cheese or your fingers like most heatsinks.

Cool with me if you wouldn't consider owning it. That's what makes things interesting.

I for one am a fan of the 866 design, especially the tilted front portion that makes the touchscreen actually usable not just a gimmicky nice to have.
in some ways it’s design is why it’s also number one in my list.
but of course everyone has their predilections.

@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.

The touch screen on the Boulder 866 is the best I've seen and experienced from any brand and large enough to be of actual use.

As a general input, there are usually a significant jump in performance and build quality when taking the step from $5-10.000 to $10-15.000 (or more). You DO usually get what you’re paying for, at least on this level before moving into the luxury segment where many other factors comes into play.

Hegel as one example is strong within the mid-segment but does not compare with a higher end amp within the higher price ranges imo.
