This is a review and detailed measurements of the Buckeye Hypex NC252MP based, 6-channel amplifier. It costs US $1149 as of this writing. The owner/builder is
@Buckeye Amps on our forum.
The looks are fine for a well-priced build:

The unit is quite light courtesy of rather thin sheet metal. I am not as worried about the top being thin but the bottom is as well and that is where heat is generated. You won't likely push all three modules to max but if you did, I would put taller feet under it and maybe even some temperature controlled fans. In my testing the bottom just got a bit warm so not a major concern.

I stopped using my Mogami Gold XLR cables because I wanted to have colored ones. I bought a batch from Amazon that is nice and flexible cabling but some kind of generic XLR connectors. I have found them to be a hair worse than my Mogami cables as far as fit. On the Buckeye amp though, I could barely get them into the XLR connectors and then back out. I tried other XLR cables and my other generic ones were also stiff. The Mogami cable however, was a bit tight but nothing as bad as my generic ones. I know tolerances very but I had not seen this level of compatibility before with any other gear I have tested. Anyway, it is a one-shot deal so not a big deal even if the problem exists.
Buckeye NC252MP Measurements
Internally we have three stereo amplifier modules. So I decided to drive the unit in stereo using first and last channels. This way we have some variation in modules and their placements. Here are the results:
Frequency response is pretty good for a class D amplifier:

I am
happy to recommend the Buckeye 6 channel, NC252MP based amplifier.
