I think this amp needs a balanced out.


Its funny how drop created this image using a balanced DAC that doesn’t have RCA outs.


Did they use the same image on the 789?

The Grace SDAC Balanced has an unbalanced 3.5mm out that could be used to connect to the AAA One’s RCA input.


@Laminator’s point is valid AND yours is too. The image is a bit misleading as the intent of the SDAC balanced is to be…you know…balanced.


Would be nice to get a peak under the hood.

Feel like they are a full year behind on this one. Also, the wait on these for a pre-order is pretty ridiculous. At this point, just spend the extra hundred bucks and get the 789.

Or save $100 and get an Asgard 3 :wink:


Preaching to the choir.

There are some people that just like that allure of the THX-AAA stuff. I was at one point, too, but after giving some other amps a go and doing some A/B testing, I agree with some people that say its a bit sterile sounding.


Agreed. It’s also NOT ‘achromatic’ as it claims. The treble is thin and sharp, IMO. I don’t argue with the fact that sensitive measuring equipment shows that THX amps change an incoming sine wave virtually zero, but something is happening sonically. I’ve had the privilege of hearing many acoustic instruments live over the years. Particularly with things like cymbals or even the upper reaches of a piano, the sound coming from a THX amp is much thinner and sharper than what I hear IRL. That change is coloring the sound from what those things actually sound like. To my ears, THX (and most other op-amp based amplifiers I’ve heard) produce sounds that are further away from ‘real’ or ‘natural’ than the Asgard or Liquid Platinum or G111, or even a super budget amp like the Liquid Spark or entry-level OTL tube amp like the Darkvoice. Thus, I can’t get behind the ‘achromatic’ claim for THX. However, not everyone has to agree with me on that. If THX sounds real and lifelike to you [general ‘you’], enjoy it!


Below are patents from THX that talks about their tech now employed in various amps. “The purpose of this feedforward network is to add a correction signal to the output that (ideally) cancels the distortion introduced by the output stage.” The '221 patent describing the '355 patent.

I’m completely out of this Thx world that was hyped in the beginning after hearing the Smsl Sp 200.
I can’t judge the one from Massdrop and it won’t come to that.
Because I won’t see any difference between a Sp 200,789,the one and the monolith.
I suppose except for a few nuances one or the other will be a bit warmer here and there the other will be cooler.
And when I go deeper into this Thx topic I realize that it was more a sound development for big stages like theatre, cinema.
And to sum it up it is also true.
When I watch a movie in stereo and the same movie again in Thx format, I give the Thx that comes first, I really have the feeling to be in the middle of it.
If you can’t hear the stereo sound of a car driving 10 meters behind you, it’s very clear with the Thx and you can even recognize the 4 or 6 cylinder engine. :slight_smile:
I had the same feeling for example when I heard the sp 200 back then that it is much more in the middle of the hall instead of at the front where the sp 200 is mUsik actually plays.
But for listening to music I prefer the stereo version, there is still nothing better even after 50 years, not strangely enough.
And there one would like to be at the front, either on stage or in front of the stage.
But not in nowhere.
But apart from that, I don’t think the idea of Massdrop with the One is a bad idea for the small purse.
It’s minimalistically designed but still scratchy and ostentatious.
What wouldn’t be wrong is a Thx based amp with integrated Dac where the whole thing is tuned more smoothly.
Maybe I’ll keep an eye on this one for a home cinema, because you can’t complain about the price, if it had a stereoout I would think about the project :hugs:.

Have fun with it for those who want to buy it, :v:.

Hmm, what’s wrong with this picture?
