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!

I desgined a simple 3d printable vertical stand if anyone is interested. You'll need to remove the feet for it but they are on screws, so it doesn't damage it.

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.

Mine is dead after 31 months. 5 month ago, balance output was dead but I can still use RCA.
Now it is completely dead. Team?

I just got the red light of death. Apparently this is very common. Cmon team, stand behind your product. 200 plus dollars for a paperweight is absurd. I've spent thousands on your site. You'd think you'd at least give me a credit on something else.

Welp! My amp is also dead. And now i see that the discussion board is flooded with dead devices. I literally used the amp a few times only and then i got the infinite red light.
Guess ill have to sell it for parts too like a few ppl I've seen on eBay. This is incredibly disappointing.
To top it all off I bought this amp with the Focal Elex combo, and the Focal cans also died (twice) so i had to return those 2 times and then get a refund.
In conclusion may this serve as a warning for future buyers, youre better off not buying Drop branded peripherals since the quality is sketchy at best.

It is dead after 22 months. The shortest life of all my amps.
Never buy Drop anymore.
