It in great working condition. 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. 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.

Works great, looks good… All knobs and jacks are tight and work perfectly, no noise or crackling. A couple barely noticeable tiny scratches on the top, and a little bit of the black has been rubbed off on the top right corner, also barely noticeable (see pics) Basically, if you want this amp at a good price, come and get it !

DescriptionGrade : Used Operation has been confirmed with a supply voltage of 100V. There are some scratches.Included Contents: Main unit only All my products are 100% Authentic. If you purchase an electrical appliance intended for use in Japan, you may need a step-down transformer (converter) to use it because the Japanese voltage standard is 100V. Please check the voltage display on the back of the product or on the adapter if one is included. In this case, the adapter display takes precedence. First, check the voltage environment you will be using. 1. If the adapter or product display (adapter takes precedence) is 100V, 100V-, you can use it in a voltage environment up to 120V. If the voltage environment you will be using is 121V or higher, you will need a transformer. 2. If the adapter or product display (adapter takes precedence) is 100V-240V, you can use it in a voltage environment within that range. If the voltage environment you will be using is higher than that, you will need a transformer. 3. For home appliances with built-in motors (such as turntables), use a transformer with a wattage 2-3 times higher than the adapter or product wattage (adapter takes precedence).4. For appliances that generate heat (such as vacuum tube amplifiers), use an adapter or a transformer with a wattage 1.25 times the wattage of the product (adapter takes priority).Watts/Volt-Amps (W/VA) = Volts x Amps Furthermore, the shape of the power plug varies from country to country. Please prepare the power plug along with the transformer. *We are not responsible for any damage caused by not using a transformer.Payment We usually ship within 5 business days of receiving cleared payment.

A linear amplifier, the most value for money and highly rated. Suitable for headphones resistance between 32 and 600 ohms. Comes in its original package and with a pair of balanced cables (worth $70 on Apos audio). The silver Schiit DAC in the photos is not included. I attached a plastic tape on the top to avoid dust particles, and it has no affect to the functioning.

Works great! Though there are scratches on top as photo shown. also has stricker gum residue, which i would clean but i dont have a toothpick right now. otherwise in great condition. includes original adapter.
