Massdrop x THX AAA™ 789 Linear Amplifier - Impressions Thread

Haha. I mainly go there to check something I’m interested in because it seems to have the most information on source gear and advises if any device has any sort of functionality issues claimed by users. I’d normally get this info from HeadFi first but there isn’t a thread on the E30.
I like numbers but I will try out and hear any AMP or DAC. If they sound great numbers to me really do not matter. I have heard both sides to the DAC I just got the Airist Audio R-2R DAC. The number guys hated it but the audio guys liked it. The few you tube reviews on it they liked it.

I've avoided this thread for a long time now but I own a Monoprice THX AAA and I have to say it is a fantastic amp. I owned the Bryston BHA-1 and sold it to a member here at Head-Fi....This is as good, sonically, without a doubt. As good and for a fraction of the price.

Got my 789 in about a week ago, and I really enjoy it, a very nice upgrade from the Magni I had before

very pleased
Yes I also like the THX 789. What DAC do you have going with it? This is my set up. I have the THX 789 and the Airist R2R DAC.

I have got a topping D70 to go with my 789

pretty overkill tbh but it looks good and has balanced outputs and is a similar size to the 789, so it checked all the boxes
I wish the R2R DAC was balanced. Never had anything from Topping.

Realize that the THX AAA 789 is not balanced I/O so a balanced DAC makes little difference. I use the Drop x Airist Audio R-2R DAC with the 789 and am very happy with the combo.

The 789 is not bad at all, I have heard the benchmark HPA4 is just that little bit better, but it's many times the price. I'm happy with 789 for an end game solid state amp

There is a new Topping A90 headphone amp out, here's a comparison posted between the HPA4 / 789 / A90:

Soundnews also references their previous comparison video between those headphone amps in that video review, and their Youtube Details has pointers to their written reviews.

Just to be sure, if I use balanced between the modius and 789 I should only use balanced XLR headphone cable right?
I wouldn't be able to use the SE inputs?

You can still use the SE inputs.
