My Dumb Question of the Day


I feel strongly that I should ask a dumb question every day. Audiogon's turn.

When I am playing an LP I clearly hear the music when the amp is off. I know that this is how the phonograph has worked from the beginning (the old wind up Victrola at my sister's house), but is this really a good thing. Would better more efficient coupling improve the signal to the cartridge, would better damping of the tonearm improve the signal, basically, is this accoustic phenomena less noticable on a really high end turntable.

I'm using a Clearaudio Champion with Aurum Beta S and RB300 arm.

Gosh!!!

What 4 the JC sake R U talkin' about???

What kind of efficient transfer???

It's NOT sound waves are being transfered but mechanical waves of stylus induce electro-magnetic force emf across the coil of cartridge as per Faradeys' Law of electro magnetic induction. Hearing mechanical waves of stylus being transfered to the air is absolutely irrelevant to the conventional analogue reproduction.

Earlier in mechanical gromophones the mechanical vibrations of the needle were transfered acoustically through the brass horn. Well, nowdays we have better solutions than brass horns(again mr. Faradey comes very handy) and to "preserve" this "wasted" energy try to use microphones with all applied stuff such as mike amp or mike preamp input, mixer(the device that takes many input signals at the same time)... Gotta be those high sencitivity ones from recording studios next to the cartridge or simply you may use karaoke machine he..he..:-).
