CLASSÉ DESIGN PHILOSOPHY 

 
 

1. REPEATED LISTENING DESIGN SESSIONS: 

Fine tuning of sound by exchanging and mixing of parts (transistors, capacitors, wiring, PCB boards 

etc.), and adjusting many specific operating voltages within proper engneering ranges, producing an 

overall sonic recipe giving the most natural harmonic realism of music typical of instruments in a live 

performance. 

 

2. UPGRADABLE SINGLE CIRCUIT DESIGNS: 

All Classé products (all preamps and all amps) share exactly the same circuit (excluding moving coil and 

moving magnet phono circuits). This means all amplifiers and all high level circuits of the preamps are the 

same. The same circuit is tailored to different power levels etc. Differences between less expensive 

models and more expensive models are parts quality and compliment, power supply extravagance and 

the amount of filtering etc., as well as features and packaging. 

This means that for years Classé has been constantly fine tuning and upgrading this circuit and its 

application, thus reaching a very high level of understanding and musical achievement which benefits all 

models - least expensive, most expensive, preamps and amplifiers alike. 

 

3. EXTREME LONG LIFE IN REAL WORLD CONDITIONS: 

Choosing the best attainable quality parts and materials combined with the advantages of the two 

above-mentioned areas provides Classé owners with years of proven trouble free reliability and musical 

enjoyment.
