There isn't much to complain about, with regards to MMATS amplifiers. For the most part, they are rock solid.
However, after owning a couple of them for a few years... I've come across a few things that could use improvement:
A few months back, I had posted an article on how to replace the noisy fan:

Now I am posting about something that seems fairly simple... but definitely is an improvement over the OEM design:
Replacing the Crappy Philips Screws on the Power Block
Just to clarify;
If you are inserting bare copper 4awg wire, you don't need to crank the terminals down that hard. In which case; this is a total non-issue.
But when I started using copper ferrules... that's when I stripped the Philips screw heads.
The ferrules use the pressure of the lug screw to crush-down and hold the wire in place.
I replaced the Philips screws with M6 x 10 Allen Screws (actually they are called Grub Screws):

Remove the stripped Philips screws (just unscrew them all the way out):

Crank 'em down good and tight with an Allen wrench (you can tighten them way better than with a Philips screwdriver):
