I have one of those.. GREAT amp!This has nothing to do with Diamond Audio,
Mitsubishi Diamond Audio/Brand is refering to the 3 Diamond Logo they have used the Diamond name and still do for their large advertisment screens and home TV sets called Diamond Vision for a very long time.
As stated above Diamond Audio back in the early 2k was a child of Esoteric Audio and some employees of PPI.
It looks like a really nice amp dude!Good to know! It makes you think otherwise, when it says Mitsubishi in small font and Diamond Audio in large font at the bottom haha //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
