Denoting a subject of study; a branch of knowledge 

hifiology 

To describe, educate and clarify, using diagrams and text, the technical specifications and terminology relating to the subject of Hifi.  

Welcome to Hifiology - The Listening Suite 

When I was younger my main reason for purchasing a hifi was to listen to my music collection at an improved level of performance compared to at the time my inexpensive record player with built in speaker.

I always remember the excitement of listening to my Uncles stereo hifi system, recordings that I’d listened to for years through that tiny built in mono speaker now revealed an increased clarity and detail that I’d never thought possible.

A door had opened to a world of musicality and emotion that eventually led to a career in professional audio recording and live performance.

Choosing Hifi components can be bewildering and confusing, there’s just so much to choose from.

I remember the bewilderment and confusion trying to choose the Hifi components that would eventually become my first hifi system.

The technical specifications and terminology where overwhelming and at times difficult to understand.

The most important thing I learned is that the components are all interrelated and based upon their individual performance either add or subtract to the overall musical performance of a system.

These articles are to help provide a clearer understanding and appreciation of the various Hifi components, which when combined, create a Hifi system.

I hope you enjoy.

How a cartridge operates

The Moving Magnet & Moving Coil Cartridge

Moving Magnet & Moving Coil Designs

There are three types of Moving Coil Cartridges, Low, Medium, High output

 

The Cartridge - The Assembly

An electromagnetic generator otherwise known as a cartridge, can be divided into 4 separate sections.

(1) Physical - Cartridge Body, Cartridge Weight

(2) Mechanical - Stylus Type, Stylus Radius, Cantilever Material, Tracking Force, Tracking Ability, Compliance

(3) Electrical - Cartridge Type, Cartridge Output Voltage, Cartridge Output Impedance, 

     Phono Stage Load Impedance / Resistance and Capacitance

(4) Audio - Frequency Response, Channel Balance, Channel Separation

 

The Tonearm - Shapes & Sizes 

Tonearm Sections 

(1) The cartridge mounting point or head shell position.

(2) The arm or wand.

(3) Tonearm Bearing or Unipivot point.

(4) Counter weight.
