One of many Colorado retailers that displayed at RMAF this year, Fort Collins Audio hosted the debut of the TSG planar ribbon tower line array loudspeaker ($29,000/pair). Unfortunately, the speaker sat unplayed in the corner of the room when I entered, replaced by the excellent Totem Earth ($8995/pair). Connected to a Hegel H20 amplifier ($5740), Hegel HD20 DAC ($1995), and Quicksilver Audio preamp ($3900) via Kimber Kable Bifocal XL speaker cable and Kimber Select 1126 interconnects, the system was producing fine, solid sound with nice color.
