Works perfectly fine!

Selling the Drop + THX Achromatic Audio Amplifier (THX AAA™) 789 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. Made in collaboration with THX Ltd., it features the company’s groundbreaking THX AAA and feed-forward topology, which reduce distortion by 20 to 40 dB for realistic, fatigue-free listening. In fact, this bridged-output amp’s performance figures speak for themselves: It’s powerful (2 x 6W at 32 ohms) and quiet (136 dB SNR) with a record-low THD of -140 dB at 300 ohms, 100 mW. That’s four times the power of the Objective 2 amp, for example, with far less distortion. This bad boy has power in spades, and the fact it has RCA passthrough is a godsend, allowing me to easily hook it up to my turntable. Comes packed in original Massdrop box.
