Trinnov 8m 8 Channel Amplifier Review

[MacCali]

Thanks, Amir.

Absolutely stunning look and performance for a multichannel amp !

Designed in France, but Made in USA... Quite unusual.

Call me old fashioned but I'm jealous seeing the linear power supply with those big transformers.

Nothing like nice pair of large toroids

Made in USA means the Hypex modules are also made in USA as in order to be classed as Made in USA, the "product is "all or virtually all" domestically produced, manufactured and assembled in USA." I didn't know that Hypex modules were made in USA.

finished nc1200 stereo power amps are like $1,500 right? and so you need four to get this thing...

ummm.... its not out of the bounds of reason but i question why you need to get 8 channels into one chassis and all the demands it has on one psu...

if this is going into a cabinet then just get a couple of stereo units and use 4 power cables???

 

[MacCali]

Appreciate the sender of this product and Amir’s lower back.

Hmmmm I really question the true benefits of multi channel amps. Unlike stereo isn’t it much more difficult to distinguish the difference? I thought Floyd Toole did research on this, right?

 

[sarumbear]

Interesting that it seems there are two versions of the amplifier. I found this on Google. Slightly different back-panel layout as well...

NAD m28 as pointed above is about half the price and missing only one channel and I’m pretty sure it’s not far off the M23 with probably a fairly competent smps.

At the very same time I think buying more than one quality 7 channel amp and you’re really pushing objectivity too far. The floor channels will definitely have a noticeable difference if you pick it up but Dolby channels don’t fire that often I feel for it to matter. But case in point you can get 14 channels with the M28 for the price of this

Wonder what that is, maybe more power/larger modules

Case is also different,it's divided in two parts on the top,Amir's sample is just one piece.
This looks beastier though.

Edit,no,what's visible is a subcover,top cover must be one piece as well.

I added the page link where I copied the image and it seems both versions are the same, just different layouts.

Seems like it's made by ATI:

B-but... ATI is AMD for like 10+ years already

 

[HarmonicTHD]

19dB gain „only“, certainly favors the very good Noise performance.

Did anyone run the numbers yet to see how much (hopefully noise “free”) input voltage is required to drive that thing to full power?

Montebello, CA , September 1, 2016 – Amplifier Technologies, Inc., the prolific manufacturer of many of the high end audio’s best amplifiers today added a new series of amplifiers. The ATI AT54x Nc amplifiers use Hypex N-Core Class D output modules with ATI designed input buffers and linear power supplies and are available with two power configurations. The ATI AT54x Nc amplifiers use two N-Core modules per channel in a differential bridged output configuration delivering 500W RMS per channel at 8 ohms and 900W RMS at 4 ohms. The ATI AT54x Nc amplifiers are available with 2, 3 or 4 channels.

Amplifier Technologies owns the ATI, Audioaccess, BGW and Theta Digital brands and designs and manufactures state-of-the-art audio components for its own and other brands in its facility in Montebello, CA. Guided by legendary amplifier designer Morris Kessler, ATI offers both performance and value in audio components.

ATI AT54x Nc are the best amplifiers we have ever heard

Not clear but it says it uses Hypex modules, which are manufactured in Malaysia. In which case how can they say Made in America?

Well, even if it's soldered to PCB in America, components are definitely made elsewhere. So where exactly is that borderline, assembling PCB equals "made in" but asslebling unit with pre-assembled PCBs/plate amp units is not?

Ok,I think I found out what's happening.
There are two version of Amplitude8.
The one Amir tested which is the "m" version (which Trinnov says it's the cost effective version) and the plain Amplitude8 which is the big brother.
The one you found is the big one.

this is an amplifier worth drooling all over.

Better not, it probably doesn't have the appropriate IP rating

Anyway, should this thing not give a bit more power? 700W in R2 and 1200W in R2 according to datasheet. And this thing goes into protection with 2R? Why?

Even the big brother (plain Amplitude8) which is 2 Ohm rated (that one is not) doesn't reach the numbers.
PSU limited probably.
