I bet that is noisy as fuck. Long traces and no shielding - utter turd. Form should never compromise function.

  Although there's better ways to express it, you might be right. I wouldn't want this thing next to my RF power amps, cellphone devices or power tools. Turning deaf at a turn of a nearby equipment it's probably not nice. Nonetheless it looks pretty, but not as pretty as the glow of my now defunct old tube radios.

  The function of this amplifier isn't to achieve the best amplification at the lowest cost -- it's to be a curiosity piece that actually does something. It seems to perform this function admirably.

  Yet the maker says exactly the reverse in his blog... "Although there is no metal shielding as you would have in a conventional chassis/PCB the amplifier exhibits no unwanted noise or RF interference as you may associate with an open chassis design such as this it is dead silent even though it is next to my mobile phone and WiFi router."

    Just because it's next to the device doesn't mean it'll induce current in that position or at the right frequency to generate audible noise. Testing is much harder than that. I bet someone will build a clone and find out the hard way.
