Hello Friends,  Since its release in 2018, the Drop + THX 789 THX AAA™ Linear Amplifier has been praised by reviewers and community members alike. It’s hard to find a “Best Amp Below $1000” thread without a recommendation for the 789 and the incredible value it offers at $399. Now, two years after the 789’s initial release, we’re excited to announce we’re adjusting the 789’s market position.   As of April 17, 2020, we’re adjusting the 789’s MSRP from $399 to $299. This price adjustment is made possible via increased production size (thanks to you) and more efficient material sourcing + manufacturing optimization (thanks to our Product Realization team). At $299 MSRP, we’re excited to cement the 789 as a critical part of the Headphone community purchase progression.  Thanks for your continued support and feedback. We wouldn’t be here without you.

I have an original run with the "THX AAA 789" branding I'd like to part with, it's both more, and less than I need in certain areas. So if there's any interest in quick shipping, let me know.

It has about 20 hour of use, was thinking $300 shipped (conterminous US) on Saturday or Monday, in the original box and fancy bag.

I currently own a Magni 3+ and Modi 3 Schiit stack. Would this amp be a significant upgrade over the Schiit stack? If so would I need to purchase the Drop + Grace Design Standard Balanced DAC to experience balanced audio or would the Modi 3 suffice?

Has anyone experimented with using the 789 as a preamp for a stereo set up?

Yeah, I plug it with my topping D50s dac and Kanto Yu6 active speaker. There is a slight improvements, but it can be hardly told. I think it works the best for high impedance headphones/IEMs. It may work for a vinyl player as a preamp, but I have not tried it

I wonder what is the Auto off/Bypass switch for? I do not have enough money to buy another DAC and my DAC only have one RCA output. So I have to use the bypass function and headphone output at the same time while connecting to my dac.

It is as it implied, it will auto power off the amp after an hour when it doesn't detect any signals. If you choose bypass, then it stays on all the time until you manually switch it off.

Got it, thank you. I thought it would be the switch for the RCA output at the back, but that's good too.

Ships October 30th, says so in a little box on the overview tab. Additionally, the text next to the calendar icon below the pre-order button says how long you have left to pre-order. Based on demand, I doubt that there will be any left past this date though. It's also occasionally available on Amazon, if you prefer to go that route.
