Specialist's review :
(Below is a review article of very famous audiophile in Korea.
He is highly respected from so many Korean audiophiles, and he also produce top-rated amp.
and speakers.
He used Mpingo knobs several times and posted highly praise on his homepage.
Moreover, he ordered many quantities for his own amps. like below photos.
We hope this review can help your understanding for our Mpingo knob.)
The Mpingo wooden knob
"When I made the amp. a few times, I tried to use acrylic knobs with large quantity instead of
metallic knob of aluminum, brass, stainless etc. It was a more relaxed sound than metallic knob.
The fact that there are sound improvement effect of wooden knob is now widely known.
I tried to test with Mpingo knob a few days ago, then the result was amazing.
It was feeling of an upmarket amplifier a few steps upgraded.
When put it in small output (2watt to 10watt) amplifier, the sound was running smooth as if prickly
fluff did shaved and became much less noise despite of turning up the volume.
In the jazz, when clarinet are blows roughly, it often sounds close to brass.
But, this Mpingo knob gives as the tone of the woodwinds.
It can feel more obvious improvement effects than that replaced with expensive Amp. terminals or
replaced vacuum tube to high price classic tube.
This is the reason inferred from my way.
It can be feel the subtle vibrations when grasp lightly the roots/shaft of volume and selector.
This vibrations goes through selector knob to volume knob and does amplified.
Amp. chassis can make noise, but the knob is more direct than chassis.
In short, if the volume and selector is speaker driver, the knob is the enclosure to amplify vibrations.
Let’s list the sound quality in turn of knob material ;
Brass -> Stainless steel -> Aluminum -> Acrylic -> Bakelite -> Bubinga(wood) -> Rosewood(wood) ->
Mpingo(wood).
The worst is Brass, and the best is Mpingo.
In short, the replacement with Mpingo wooden knob is most simple and cheaper way for sound
improvements.
It is more effective to replace volume and selector together.
Also, it is better to keep out of contact with front panel when put the knob to the shaft."
Buyer's review :

After installing Club Wood knob and cable damper, the sound of my audio system improves.
Listening to the music is now more relax and enjoyable.

As a result, everybody surprised to the sound difference caused by only one volume knob.
Our choice is Mpingo knob naturally which tone color become more calm and stable."

we feel dramatic effect like replacement of source or pre-amp."

articulated sound of musical instruments."

are disappeared."
