Zaike...$159 is the price on the website. I think that Parts Express price is the same. But I'll go with $129 if you accept that the original model has been sold for $19.95.
The darned thing is so lightweight that it's hard to find a way to "install" it in a system. One idea that would work would be to remove the tiny circuit board from the plastic enclosure and build it into some speaker wires as a bulge. Now that would truly be "magic" speaker wires. Connect your preamp directly to speakers.
