Product Description
Announced at CES 2018, the Drop + THX Achromatic Audio Amplifier (THX AAA™) 789 is a linear bipolar amplifier with feed-forward error correction. It’s designed for objectivists who appreciate an incredibly clean, transparent amp—the sought-after “wire with gain” whose amplification is wholly uncolored by a sound of its own Read More
