Shun Mook Audio Mpingo Disc

RARE! RARE! RARE! 
The Mpingo Disc is invented by the Shun Mook team. It is made from a combination of Gaboon and Mpingo Ebony, treated with a proprietary process that gives the disc a unique property to regulate the resonance of any sonic component and its transmission. Yet this is a very simple item to use. Just place one to three disc on top of your preamp, CD transport, DA converter, turntable etc, and listen for the wonderful change in your Hi fi system. When this disc is excited by any external acoustic energy, it will resonate throughout the entire audible spectrum, thus overriding unwanted harmonic distortions and at the same enriching the musical reproduction.
For fun, I placed a mpingo disc on the top of each of my Audio Engine 5+ speakers and another on the face of my iPhone I have connected via Audioquest Yosemite iPod cable  to to AE5+s. (That's 3 discs in total). The sound became immediately more open, focused and extended in bass, less edgy in the midrange and lower treble regions of vocals and instrument strings in particular  An overall great upgrade! Quite a bit more in sonic value ROI than the $270 the 3 discs cost.! :-))
I'm selling these for $80 EACH and will include shipping. They are mint. They are not currently available from Shun Mook, I will NOT be package pricing them if you desire more than one. I have a very limited supply. Once they're gone, they're gone.
Thanks so much for your business! I appreciate it!
