Product Description
We teamed up with THX to build a leaner version of our beloved 789 amplifier. With THX AAA technology, three gain stages, and a new preamp output, the Drop + THX AAA ONE has all the essentials, and nothing extra.

Streamlined Amplification, Ultra-Low Distortion

Listen to our Audiophile Community, and you’ll hear that headphone amp users want two things: an accessible, solid-state competitor—and more THX. We took care of both in our latest collaboration: the Drop + THX AAA ONE Linear Amplifier. Designed for entry-level listeners and enthusiasts in search of a refined feature set, the THX AAA ONE is a slimmed-down version of our beloved THX 789 linear amp. It does away with the 789’s balanced inputs and outputs in favor of a single-ended output and an all-new preamp output, which is perfect for connecting to powered speakers. Of course, it also features THX’s legendary AAA technology to deliver detailed amplification with next to no distortion, as well as three gain stages to drive headphones at all impedance levels. With everything you need and nothing more, you could say it’s the ONE.

THX AAA Technology, Plus a New Preamp Output

Inside the Drop + THX AAA ONE Linear Amplifier, distortion is all but defeated. Harmonic distortion, crossover distortion, intermodulation—these unwanted symptoms of electric current are reduced to nearly imperceptible levels through THX’s patented AAA technology. With distortion up to 40 decibels quieter than competing Class-A amplifiers, the Drop + THX AAA ONE transmits audio in its purest possible form to any pair of headphones. Select from three carefully calibrated gain stages to drive sensitive IEMs, high-impedance dynamic headphones, and everything in between. Switch to an all-new preamp output using the dedicated “Pre” button, and pair the Drop + THX AAA ONE with powered speakers or a power amp for crystal-clear preamplification. Finished in a sleek and strong aluminum housing, it’s sure to look (and sound) great wherever you set it.

About THX Ltd.

You may know THX from the goosebump-inducing “Deep Note” played before many blockbuster films, but the company has been associated with high-performance audio since its founding by legendary filmmaker George Lucas in 1983. The THX system isn’t a recording technology, but a certification. For any theater, product, or work to become THX certified requires a rigorous set of criteria. If these qualifications are met, the resulting sound is as close to what the mixing engineer intended as possible. From home-theater systems and headphones to gaming consoles and productions on the silver screen, THX is committed to delivering the most immersive audio experience achievable.

Question
Can it be used as a preamp and take as input a phono signal? The output of the THX AAA One will then feed into a power amp. Will this configuration work?

If "phono signal" means the output of a phono preamp, this will work. The raw output of a turntable without a built-in phono preamp will not work. It must be amplified and equalized by a phono...Read More
