Does it annoy you when companies don't show the internals of electronics ?

Mark Levinson insides look impressive. Sound, unfortunately, is not.
Tekton insides look a mess. Sound, fortunately, is quite the opposite.

Sometimes a look inside is worth a lot. When learning about Schumann generators there was a review of some $400 thing that had a picture of the inside that showed clearly all that is in there is the exact same circuit board sold on eBay for $12.   

Now really when you think about it, that is exactly what you are going to see inside virtually every component. Only instead of just one board its caps, resistors, wires, but all of it the exact same thing you can find for pennies on line.

No kidding. Just TODAY in fact there's a guy with a really expensive well regarded phono stage and he's replacing the diode with the exact OEM part and it costs fifty cents. 

When I suggest upgrading that one part to get significant improvement, another absolutely empty suit who shall remain nameless claims this can do nothing.  

So here in a nutshell is the true nature of having a look inside. We simply know so little of what matters and what does not. We can look all we want. In the end, if it sounds good then we can only admire the way it's put together. If it don't, well then who cares how it looks?

Let me be clear. I am not suggesting something that is not visually appealing or seems wrong from an engineering standpoint will sound bad (ie. wells audio internals that look like a train smashed into a pile of IEDs). But sometimes I think part of the joy of ownership is knowing whats inside your electronics and see the great care that was put into the design of the devices.

Okay then let me be clear: You take your screwdriver....

And transformers- what are they hiding?
