Massdrop x THX AAA™ 789 Linear Amplifier - Impressions Thread
Nov 19, 2019 at 1:24 AM Post #1,876 of 2,591
Call me crazy, but when I get my 789 on Friday I'll be up for testing potentially 3 power supplies.

If there are ZERO benefits from the CSI5003XE thennn I probably won't consider the black LPS. But we'll see. If there is a slight change in sound and for the better (blacker background, yadda yadda yadda) then I'll need to pickup the black LPS in 24V.
Not crazy at all. Please report your findings. I am considering a custom built LPS from MCRU.

Great review, Amos! One of the best things about the 789, to borrow a line of thinking from Andrew Jones, is that the value it represents allows one to apply the savings to a bigger budget for upstream gear like a DAC. In my case, the combo of the 789 with the R2R-1 is an excellent match, as the components are of similar sound quality.

Imo. My HUMBLE opinion. I believe there is less fatigue at the very least when using my LPS.

Currently auditioning the 789 with my K712. I cant imagine what balanced will sound like, after i make my balanced cable :)

So far the 789 is turning out to be a wicked piece.

Still waiting for my Canare cable to balance mod my K712 cans. In the meantime, @lator i'm curious how the MCRU LPS will turn out. Now, i'm thinking Sbooster BOTW! They sell a 24V. Though, it is twice the cost of the ebay LPS. This all could be for sound quality better or worse, but it's the adventure that makes this fun :)

Sadly I can't find out in a while. Our country has a month long postal workers strike and now also air/sea travel is joining in so probably can't get anything delivered in for a long time.

got one of the new drop branded versions today and right off the bat i can say the fit and finish was nicer on the older unit i have. this one is not at all what i would call bad but there are a few tiny spots / things i see right off the bat and the paint at least on this one while nice is not as nicely done and even as the older ones i have (i own 2 of the older massdrop units both are nicer overall imo). if someone did not have both to compare though i think most would be fine with the drop version. the front face panel is not exactly straight on one side it sticks up higher then on the other same on the back, there are a few small specks in the paint and one tiny bare spot on a back corner that can be touched up easy enough its VERY small. they added an indicator on the volume knob now and the switch on the back feels MUCH stiffer then the older one its much harder to click up and down. i hate the new logo design plain and simple. why they did not change that before production is beyond me. three different fonts on the front makes it look cheaper imo. they have totally different serial numbering now and its printed on the unit now instead of a sticker. ill sit down with both units tonight and tomm for extended listening and see what if any at all sound differences there are but i think its just cosmetic from what ive read. as i said overall if i had to keep one it would be the older one when looking at fit and finish overall. but i do like the new volume knob better.

one other thing is the selector knob is actually nice and straight on this one when you set it to 2 its nice and straight. same for 1 and 3. one of my old ones is way off and the other is close but not as close as the new drop version

Can you post pictures of the newer unit? I have an older one, but I'm curious to see the cosmetic changes to the Drop-branded THX AAA 789. The pictures on the product page are obvious photoshops of older units.

Just my two cents,

As a new owner of a new 789, I notice how clean & quiet it is, definitely worth the wait & trouble to get it.
Still amusing how much the hype artist reviewers hyped this particular amp up.
Definitely a nice addition to the collection.

Hope everyone has a great day !
