CES 2007

DEQX's PDC3 preamp/processor (price tdb) combines an analog preamplifier with a DAC and measurement-driven DSP. In a hotel room with zero treatment, Jon Iverson and I were enthralled by the three dimensional soundstaging of a pair of B&W 805s and a pair of B&W ASW 700s. Nope, it wasn't because the CD player was fabulous, either—it was solid, but not audiophile approved.

"Come back later," Sasha Case said. "We're going to demonstrate our new active, adjustable crossover and that's a difference that isn't even debatably subtle. It's amazing."
