Audio

System - What audio equiments I use.

 

DIY

During the past few years, I've DIYed several audio projects.

Speaker

A pair of speaker I built based on ScanSpeak. The box uses 1.5" thick MDF and have internal bracing to kill colorization.

   
 

Gainclone

With 6 or less components in each channel of an amp, this is problbly the easiest and cheapest amp to build.

   
 

PI7293

Parallal Inverting 7293 - the TDA7293 chips allows me to parallal 3 chips easily for more power - more than 100W. PCB board is used for this design.

   
 

DI-Pre

Dual Inverting Pre-amp - 3 inputs, parallel to a pair of OPA627 and a pair of AD8610 which allows me to compare these 2 high-end opamps.
