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
Balanced output for better compatibility and channel separation. Lower single ended power, but significant power through XLR, which the Atom does not have.
How do I connect this to my computer? I have an rca cable and I plugged it into the headphone jack of my computer while connecting the red and white cables to the input on the back. When I turn it on I hear a loud static noise.
Headphone jack on a computer is amplified through a typically crappy amp. This is a great amp. Garbage in, garbage out. Get yourself a DAC which will connect to the computer via USB and then connect its output to the THX. There's lots on here to pick from -- Topping, Grace Design, etc.
Reporting a red light of death. Just happened. Went to listen to music, turned up the volume knob, and nothing. Red light is on all the time. Checked the power supply; it's working fine. Unplugged, plugged in. Nothing.
Now that I've had this happen, I see that a lot of others have, as well. Anyone look into this. I saw the replacement of the Q4 transistor at the power inlet. Could do. I can work with surface mount devices. I've read reports of burned components. I removed the board to see whether anything was immediately, easily apparent, and did not see any issues. Anything?? It can't be everything that's wrong, and there aren't so terribly many components on the board.
After all the hype and hoo-haa around this amp over the last few years, it looks like the quality was rock bottom and its essentially a disposable item. Very sad to see. I always wanted one of these and came back to order one, but it is discontinued (probably because Drop is losing it's ass on the warranty claims).
Since so many people seem to be posting that theirs died, it's hard to tell what the actual lifespan is for these amps. I wanted to note that my relatively early unit (pre-Drop branding and in use since Aug 2019) is still working. It's been my primary amp and has been powered on almost constantly since I got it. I regularly use the front 4-pin XLR and the 1/4", both usually plugged in at the same time. In the back, I use the RCA in and RCA passthrough.
bamcgregor89nah mate lol, i've had my 789 for years as a daily driver she's still kicking. in fact she's just starting to have some POT issues and I came around looking to snag another one.
REALLY NOOBY question as I'm new to this. I want to connect the Drop + THX AAA 789 Linear Amplifier directly to my PC. I' m not sure how to connect it to my PC. My PC has a Line In, Line Out, Mic In, C/SUB and REAR port on the back and I have a Beyerdynamic DT 1990 Pro so it's a single ended connection. I have a RCA to 3.5mm cable. Where does the RCA cables connect to and what does the 3.5mm cable connect to on the back of my PC? Also, when the INPUT button is fully pushed in, is that the balanced or single ended input? Thank you!
Just reporting another dead amp, It was working fine, then while trying out some new IEMS I noticed it seemed really quiet, then I got a pair of HD800s and could hardly hear them even with the volume cranked to max on the amp, searched around and saw this is a incredibly common issue with these amps, and apparently drop won't do anything about it, which is very disappointing.
I've spent a decent chunk of money on this site, and had previously recommended it to other people for stuff like headphones, but as it stands I will never purchase another thing from this site or recommend it to anyone, since drop won't stand by their products.
