Wait, it can't be a coincidence that this thing's called 789 while Monoprice's offering's called 788: https://www.monoprice.com/product?p_id=24459 seems like the same thing just that the Monoprice has a built-in DAC as well.

Oh yeah, dac and headphone amp. Same tech do you think?

It is the same tech. I forgot that I had made a request over there, when finally they were to be back in stock. I don't need a dac so this would be the better deal (for me).

This amp has 4x the rated output power though.

1. That Monoprice included AKM DAC with DSD capability, less 3W is a good deal for only $130 more. Plus, I could hook up the Monoprice DAC to my 2 channel home audio system too for an instant upgrade for my CD Player's sound (use as a transport). 2. Only Monoprice concern, I don't really trust Monoprice's products, as I ordered 100 pcs of 1/8" to stereo RCA connectors for work (in-store demo systems at Costco) and ~50% of them failed in less than a month (they offered cable replacements for lifetime, but the labor to switch the cables out in over 80 stores cost nearly $4k) :( 3. Monoprice does have a 30 day return policy on their house branded products. 4. Kind of concerning that Monoprice has this coming 8 days after this unit drops--it usually takes them a few months to knock off someone else's design. I speak from personal professional experience--the "Monoprice Premium Hi-Fi DJ Style Over-the-Ear Pro Headphones with Mic", is a design I developed for a former employer at Ocvaco (ODM/OEM Contract Manufacturer)--my employer didn't want to buy the tooling, so Monoprice came in and out sold our product 1000 to 1 and a retail cost that was close to our landed cost! I love free markets in communistic countries!

Just like this Massdrop x THX AAA 789 amplifier, the Monoprice Monolith Desktop Headphone DAC/Amplifier (with a THX AAA 788 amplifier built-in) hasn't been released yet.
Similarly, the Monoprice 788 features THX AAA amplifier technology... and adds an up-scale DAC, a full array of digital inputs, Dirac Sensaround processing, and a front LED display. While its complete specifications have not been revealed, a member of the Monoprice staff responded to a customer's inquiry regarding power output:
300 Ohms: 648 mW 32 Ohms: 3180 mW 16 Ohms: 1591 mW
The numbers likely correspond to its XLR balanced out - not its 1/4" output. So while the Monoprice 788 amplifier section is not powerful as the Massdrop 789 amplifier, it should still be powerful enough for all but the most power-hungry headphones.
For $130 more, the Monoprice 788 should be an excellent option for those looking for an above-average DAC/amp combo with a fair amount of power on tap, various inputs/outputs (including a balanced-out), and Dirac Sensaround processing - which could be a game-changer for headphone listening if it performs as described.
Information copy-pasted from the Monoprice Monolith Desktop Headphone DAC/Amplifier product page:
The Monolith Desktop Headphone DAC Amplifier features cutting edge THX AAA technology to bring out the best in your headphones, playback device, and music library. It utilizes the THX AAA-788 amplifier design for an impressive 2x1500mW of high-powered amplification with the world’s lowest distortion and noise. It also features the new flagship AKM AK4493 32-bit stereo Premium DAC with VELVET SOUND™ technology, Dirac Sensaround II decoding for an expanded larger than life soundstage, and a host of balanced, unbalanced, and digital inputs and outputs to ensure users have plenty of ways to connect their playback devices for a high-quality listening experience.
THX AAA Technology:Reduces harmonic, intermodulation, and crossover distortion by 20-100x for an unbelievably realistic and fatigue-free listening experience, and can reduce power consumption by a factor of 10 for incredibly long battery life. It accomplishes this using a patented topology to null conventional distortion mechanisms and reduce bias current.
AKM AK4493 DAC: The AKM AK4493 is the new flagship 32-bit stereo Premium DAC. Digital input supports PCM inputs up to 768kHz and DSD input of 2.8MHz/5.6MHz / maximum 11.2MHz the industry's highest level. Internal circuit employs a newly developed 32-bit Digital Filter for the ultimate in sound quality and musicality.
Dirac Sensaround II: Music is usually mixed with loudspeakers in mind, not headphones. As a result, headphone listening is often plagued by a distorted soundstage—instruments and voices may seem incorrectly placed and trapped inside your head, causing an unnatural listening experience that can result in listener fatigue. Dirac Sensaround II takes a different approach. Listeners can enjoy their favorite media in a way that seems to spread instruments, voices and objects out into space, enveloping the listener exactly as the artist intended. Dirac Sensaround II creates a vast, clear and realistically immersive soundstage free from the constraints of the space in your ear, much like a multi-speaker home theater system. This feature can be toggled on or off.

But you trust Massdrop manufacturering credentials?

Probably more than Monoprice? Monoprice has more than their share of great ideas that disintegrate in your fingers. Or fizzle if they're plugged in.

Concerning your number four observation, Monoprice has had the THX-AAA amp listed for four months now? I think they were an earlier adopter than Massdrop for bringing a product to market. Even though they haven't had any official release yet.

Andrew said this regarding the Monoprice product and Massdrop's: AndrewMason75 THX Ltd. Analog & Power Engineering Expert 12h joshy_bennettHi joshy_bennett . Compared to the Massdrop 789, the Monoprice 788: -uses the same AAA technology -788 has less output current/voltage/power -788 no true balanced output (has XLR-4, but it's only driven single-ended) -788 includes a DAC selected by the Monoprice team.

Checking the Monoprice website, the Monolith 788 has Dual AKM 4493 DACs & Dual AAA-788 Modules, and its XLR-out is fully-balanced. https://www.monoprice.com/product?p_id=24459

Which means the previous comment given by Andrew Mason was simply aimed for sabotaging Monoprice’s great product. That’s the way to go, M***drop!

I thought Andrew Mason was either the designer of this amp/the THX AAA topology/works at and for THX. I may very well be wrong but if so it would not be logical to sabotage your own technology.
