(This Australlian buyer have bought Mpingo Headshell damper Denon model on April & June 2015.
He sent his review to us, and so uproad here with his permission.)
"Thank you very much! I love this wood spacer.
Used the first one on an Ortofon Quintet MC Mono on a Sumiko metal headshell.
Very nice sound improvement!
This one I will use on a Denon 103R on Yamamoto Sound Craft Carbon Fibre headshell.
I'm sure it will improve this cartridge sound also."
