Dead horses and plinths ........ What is really going on?

Posted by Elmo (A) on June 24, 2005 at 05:53:51

Plinths seem to be a fairly common point of many posts and threads the last few months. Of course usually related to Lenco's specifically. In my case though, I'm trying to more clearly understand what contribution the plinth has to the overall sound, as heard by me at the listening seat. With my single layer plinth, belt driver.

There is talk of material density, and the material's propogation speed. As relates vibration/energy/excitability of the material. Even talk of increase/reinforcement of specific frequencies. And ..... yes subtraction of a specific narrow spectral band.

I haven't given it a mountain of thought, and well it looks like I'm only just beginning. The little effort I've devoted to the question, gives me something along the lines of even inert, strong, and 'quiet' materials still storing some modest amount of energy. Being in a very small constant state of excitability from the itsy bitsy teeny weeny little ole stylus. The cart's electromechanical generator then also 'reads' this addition along with the actual groove content.

Giving life to vinyl playback. Instead of a clinical rendition of a collection of sounds. I haven't taken a stethoscope to my latest acrylic plinth. Not something I normally do, or do often in tweakdom. But I have done it before none the less. So, I'll give that a listen.

Mostly I'm interested in a simple, concise explanation --hopefully correct -- of what's really going on? That the non math majors like myself can put a handle on.
