Re: MMF-5 Test Try this!

Can't do your test precisely as you wish because I don't have an amplifier with a headphone jack.

However, on your # 2, ear to dustcover --- I can hear the motor running but it doesn't sound like "hum" as in 60 cycle hum, just the motor running and some slight vibration transfered up through the dustcover. You could describe it as a humming type sound but it is very faint and again it doesn't sound like 60 cycle hum sounds like.

Cranking the volume on my amplifier with table running, belt off or on, tonearm in cradle, again there is no "hum" as in what 60 cycle hum sounds like. There is a relatively small amount of "hiss" and I can slightly hear the motor running, same sound as what is transferred through the dustcover. A hum type sound but it is very low level and its definitely the sound of the motor. Now maybe magnetic motor noise technically is a 60 cycle hum so maybe I'm describing it wrong. Anyway, moving the tonearm doesn't increase it whatsoever, even as close to the spindle as possible.

In my analog system, there is the MMF-5 with a Shure M97xE cart, a tube phono stage (Cornet) and a hybrid integrated amplifier (Jolida 1501RC) the noise level, even with the volume cranked (100 watt per channel amp) is low level enough that you wouldn't hear it on soft passages of music. You'd have to be pretty close to the speakers to even hear it between tracks and you would hear the "hiss", not the motor noise as that is barely audible up close to the speakers.

Hope that helps some.
