[QUOTE="thylantyr, post: 4152120, member: 560358"] I have a better than average idea on what the zuki story is, but I haven't talked to him personally, I'm using data from others and doing general detective work to see what all the hype is about. More info trickles in daily, but I don't need much more to understand what is going on here. A good amplifier mystery is always interesting to pursue. Here is the root cause of all the noise in cyber about the Zuki product. Zuki needs to improve his marketing skills, isn't a technical person, and doesn't really know what his amplifiers do on the test bench because no tests were done, hence the silly amplifier rating posted on his website. Once you get some tests done and his marketing skills improve and he posts the real numbers on the website, there is no mystery here. Judging from hs internet behavior spanning many forums, when you read his posts you see that he's an old school home and car audiophile with no technical knowledge, but he seems to love audio and has this desire to have his own audio business. Nothing wrong with this. Maybe it's a side project for fun. I have to give him credit where it's due. For someone who hasn't one clue about electronics, he was able to find someone to build him what appears to be a good product, passing this judgement only by looking at newly released amplifier guts pics. If someone does amplifier testing, a solid conclusion can be made. Right now we have a better estimate on what his 5w x 4 amplifier really does. People are speculating 75w x 4 @ 4 ohms, 125w x 4 @ 2 ohms. When the Zuki 4ch guts were revealed on the DIYMA forum, three things happened. The amplifier looked like a 1997 Genesis 4 channel design but with more 'stuff'. The Genesis guy says there is no similarities, no connection between them and Zuki. Certain Genesis, Soundstream, and the Zuki 4ch amplifiers have similar component placement methodologies. This isn't enough information to say there is a link to those three products. But someone pointed out one very tiny thing, I zoomed in at the pictures as it was 'weird' and I started to raise some hell on the forum --> "look at this 'points finger' ", long story short, this little thing is common on all three amplifiers, something very strange not seen in standard amplifier design and all three of those amplifiers have this. Is this important? no. Why does it bug me? It's another mystery to solve. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] We know that amplifier design is just recyled over and over gain. The core of amplfier design is an input stage, VAS stage, output stage, this is common 3 stage amplifier. You can add more 'stuff' around this, but the core designs have a lot in common, home audio, pro audio, car audio, the class AB design doesn't change much. When you see something weird in the core design, this implies a 'designer fingerprint' and designers are creatures of habit, if they did another design they use the same methods he used before. If someone were to copy that design unbeknownst to them they are also copying the 'fingerprint', then you raise more questions. My own personal curiosity on this 'fingerprint' led to more questions because I was curious on who came up with this idea? This really has nothing to do with Zuki, I just wanted to know why someone would do that circuit design methodology because it's not common at all, yet it's found in certain amplfiiers from two well known manufacturers. [IMG]//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif[/IMG] When I pursued this in more detail, I got some people @ Genesis very angry but I needed to see what the skinny is. As it stands right now, I think Zuki got inspired by a certain Soundstream/Genesis designs since there are considered 'reference designs' from an audiophile point of view which fits the Zuki ideals, plus the amp guts reveal inspiration. This is all speculation, no hard proof. There is two schools of thought. He had that one Soundstream designer from the older days design the amp as it has that unique fingerprint or he found an offshore product that was influenced by Soundstream/Genesis and those folks copied + modded. Genesis denies a connection to Zuki. Usually when things are copied offshore, they are straight up copies, they don't copy and add more stuff, that's why I'm ruling this option as my second choice of who designed it. But, it is possible that a certain amplifier somewhere could have been a straight up copy. If Zuki had money, maybe he just hired a certain individual to do the design? The designer left his unique fingerprint in the Zuki. If you really want to dig deep and learn more, this is the blog of babble. The writing of this blog is in the theme of 'Conspiracy Theory' to raise the suspense level of the drama, if you like to read mystery novels.
