In writing about the distinctive-looking products of Tri-Art Audio, all of which are made with sustainable-yield bamboo, and all of whose model names include either the words Pebbles or Bam Bam—not the cultural reference you might expect, but that's a story for another day—I scarcely know where to begin: Their combination of open-baffle loudspeakers, battery-powered class-D amps, and record player with bamboo plinth, bamboo tonearm, and bamboo platter impressed the heck out of me. The watchword was detail, but detail without brightness or artifice—and this system's spatial performance was remarkable: Even while sitting almost directly in front of one Tri-Art Bam Bam 5-Open loudspeaker ($CAD3400/pair), I heard exceptional depth-of-field, not to mention great touch, impact, and openness.
