This project is the result of a long distance cooperation between Edmond (a Dutch retired electronics engineer) and Ovidiu (a Canadian engineer). They met online on the www.diyaudio.com forum and soon both identified some sort of synergy that would enable a dream to become true.

The project scope was defined in the early 2007.
Key performance requirements include:

•· Class AB topology, 100W into 8 ohm and 200W into 4 ohm
• Bandwidth of minimum 20Hz to 20KHz +/-0.1dB
•· Under 1 ppm (80KHz bandwidth) THD (that is, 0.0001%)
    at all frequencies between 20Hz and 20KHz and output
    powers between 1W and 200W
• Under 1 ppm 19+20KHz CCIF IMD (that is, 0.0001%) at all
    output powers between 1W and 200W

Ovidiu was looking for a front end for his already built HEC Output Power Stage (OPS) and this is where the journey began...
