Audiophonics AP300-S2503E : Points clés

Audiophonics AP300-S2503E : 3e Audio PFFB Amplifier Module

The heart of the Audiophonics AP300-S2503E is its 3E AUDIO 260-2-29A PFFB amplifier module. This amplifier is based on a meticulous Class D architecture, enabling it to develop a comfortable 2x250W of power under 4Ω. Power that goes hand in hand with sound reproduction of great precision and richness. To achieve this, the module uses an advanced feedback design (Post Filter Feedback) as well as a proprietary error correction system (PurePath™ Ultra-HD). The latter enables it to achieve an extremely low level of distortion across the entire frequency band, enhancing its sound quality.

Je l’ai acheté pour driver mes Golden Ear BRX, ça matche ! De la finesse, précision, richesse des timbres, de la dynamique, l’image stéréo et la spatialisation sont magnifiques , ça coche toute les cases à mon goût. Encore une magnifique réalisation d’Audiophonics , merci pour cette réalisation à tarif contenu, permettant aux mélomanes a budget contenu de profiter de pouvoir assouvir leur passion sans se ruiner !
