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. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
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. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
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.

this blog is in the theme of 'Conspiracy Theory' to raise the suspense level of the drama,
if you like to read mystery novels.
