Unsurprisingly, given the difference in size and driver complement between the two models, the Argon7LS floorstanders could play far louder and far deeper than the MG-10 minimonitors. When the Esoteric speakers were asked to play loudly, they didn’t misbehave in any egregious way, but they did compress the signal and, more problematically, shifted the frequency balance toward the treble. The Amphions simply got louder.

The MG-10 has average bass depth for a speaker of its size, but I’ve always been impressed with the cleanliness and articulation of that bass. When driven by the NAD, however, the Amphions matched the Esoterics in bass articulation and thoroughly trounced them in both depth and impact. Bass performance was closer when driven by the Graaf, with the Argon7LS speakers still leading on depth and impact, but slightly trailing the MG-10s on articulation. When driving the speakers with either amplifier, however, the MG-10s rendered Christian McBride’s bass on “Armando’s Rhumba” with a little more tonal specificity. Both speaker models energize the same bass modes in my room—that’s just physics—but the significantly greater bass capabilities of the Amphions meant they benefited more from equalization; the Esoterics simply can’t overload a room with bass.

Despite the similarities, the R 8 and R 3 Arretés are very different speakers. Start with the fact that the R 8 Arreté is much larger, has several additional drivers, and weighs three times as much. The R 8 is a complex speaker, which, as I wrote in my review, “sends energy out into the air via no fewer than nine sound-radiating openings, only four of them—the three midwoofers and the tweeter—firing forward. The others are the down-firing woofer (which radiates through those base slots to the back and sides), the rear-firing midrange driver (diffracted through those five horizontal grooves), the vent that allows the tweeter’s back wave to emerge from the rear, and the two aforementioned ports.” That’s a lot for a designer to integrate, though with the R 8, Ole did a superb job: As I wrote in the review, “what I heard from the R 8s was anything but complicated: It was pure and coherent and easily grasped.”

No less importantly, it demonstrates that the Triangle is usefully sensitive as the 50W of the Brio is more than enough to drive it to any level you might want to achieve in a normal room. The rest of testing takes place on the considerably more powerful (and expensive) Cambridge Audio Edge A, which delivers some commensurate gains to the performance, but the fundamental positive qualities of the Triangle remain unchanged throughout.

You can take this to mean that the BR08 won’t necessarily elevate every single system it’s connected to but a rather more positive view would be to see this as a fine speaker to upgrade a relatively affordable existing system.
