Welcome to the Audiophonics website.


The Best Audio System in the World is the system you have at home and are happy to listen to!

Audio is a very personal experience and there are few absolute rights or wrongs in it's enactment. Each of us hears in our own way and hearing itself is a very complex phenomenon. The end desire is to listen to sound with sufficient clarity that we can enjoy the performance without concern of the mechanics of it's reproduction.

My philosophy is to keep the audio path as simple as possible without compromising the nature of the original sound i.e. "Do not complicate beyond necessity!" 1.

My current system consists of a preamp / line-driver and a pair of mono-block power amplifiers with separate power supplies.

Zeus Audio Path Schematics

The above schematics show ALL the components for one channel in the entire audio path from input to speaker. Note that there are just four transformers and three MOSFETs (1 SE in the preamp + 2 PP in the power amp) and a handful of passives.

This two stage amplification benefits from the high output levels of modern sources (TV, Video, CD, DVD etc.) and represents a different arrangement to that used conventionally. Effectively I have the first stage of the power amplifier in the preamp, and then use separate mono-block power stages which can be placed next to their respective speakers.

I use transformers by design as the primary building blocks and gain stages and either tube or solid state devices as followers. This topology is further explained on this site.

This is the system I listen to on a daily basis, both for music and for general viewing of television or DVDs.

I hope you find these pages of interest.
