pls read...I saw new things for sound quality

[space2000]

Hi all.

today i saw new device that reqire no power supply but it's sound so great that i ever listened. all are very sharp and clear sound. bass is so nice.....oh my god.

connection: amp output goes to the device and the speaker connect to the device output.

inside that i saw: There is no any circuit device only one valve transistor(or other things but looks like valve transsitor) and 4 resistor, one cap. the man said valve only using filament. when you conect this device sound quality so diffrent by 1000 times btr then any amp. NO POWER SUPPLY REQUIRE.

the device cost is only S$140.

if you know about it, pls let me know how to make this device.


thank you all...

I have posted some pictures of it at this forum. It is, of course, a hoax. There's no sound difference in a blind test.

thank you.

It might be called hoax or hype

hi, where can i get circuit design for hoax? how about the valve..?

thank you.

Hi Space2000

No idea where you can get the circuit...I could not care less either.

Here is a nice explanation of 'hoax', its an adjective for this device, not its name
http://en.wikipedia.org/wiki/Hoax

The valve is doing nothing there..., the only thing that seems to be connected is the heater, which is actually a non-linear resistor.

... and from the photo, it looks like everything is soldered to the + wire.

It looks like another brilliant idea which can open blind-and-stupid-but-rich people's wallet.

Correct. I had this thing in my hand, and asked the seller to explain how it worked. He declined, citing 'intellectual property'

BTW, there's also a line-level unit...
