3E Audio 260-2-29A PFFB

Balanced Class D Amplifier Module TPA3255 BTL 2x260W

3E Audio PFFB Module Amplificateur Stéréo Class D Symétrique TPA3255 2x 225W 4 Ohm

The 3E Audio 260-2-29A PFFB module is a high-performance Class D amplifier that can operate in stereo (BTL) mode. It is based on the use of TPA3255 amplifier chips allowing it to develop an important power of 2x260W 4Ω. A power that it provides while revealing a precise and dynamic restitution. It incorporates an advanced feedback design (Post Filter Feedback) and a proprietary high speed error correction system (PurePath™ Ultra-HD). This technology achieves a very low level of distortion across the entire frequency band and superior audio quality.

By combining Post Filter Feedback, an enhanced input stage and high quality components, the 3E Audio PFFB module achieves incredibly low noise and distortion for clear and transparent playback.

3E Audio 260-2-29A PFFB review by Audio Science Review (Amir)

" I am amazed and pleased to see how much performance is extracted out of the TPA3255 class D amplifier IC here. Clearly a good designer is at work here. Noise and distortion are kept at a minimum while producing lots of power. There is some increased distortion at higher frequencies but that is a small consideration in the context of this class of amplification. "

3E Audio 260-2-29A
The module is made of very high quality. I connected a 36 volt 400 watt power supply to the power supply, but set the voltage to 38 volts. After working for more than 6 hours, the amplifier radiator is slightly warm. I'm happy with the sound, everything is in its place. A few comments (maybe the manufacturer will take into account) - it would be good if an XLR-RCA input switch and missing chips were installed. The delivery was very fast, thanks to Audiophonics.

mejor que purifi
Tuve una PURIFI con la desastrosa SMPS hypex y sonaba estéril y enclenque. La devolví. -purifi con fuente de alimentación lineal hubiera sido perfecta sin embargo pero no se hacerlo porque es multivoltaje - . Encargué este módulo por sus buenas medidas aprebachando que la impedancia mínima de mis cajas no es demasiado baja -este no es estable a 2 ohm como purifi- pero como es un solo voltaje se le puede meter fácil un toroidal y una fuente no regulada lineal...resultado: con un previo realmente cálido/transparente como el perfecto Glasshouse TVC, la resolución es infinita el detalle el realismo , calida valvular sin ruido pero con cuerpo con grip emocionante ¡Mucho mejor que la típica Purifi o NCORE con SMPS hypex -probablemente con una SMPS Meanwell hubiera sido mucho mejor+! Brillante suena mejor -con un previo TVC - que la clase A

2eme avis..
Si vous montez une iec avec un porte fusible, l' ajout d' un fusible audiophile, même pas cher (aucharm alliage argent... 5€ par exemple ou un gustard a 20€) optimise les rendu sonore de ce petit bijoux !!

Parfait, à un détail prêt.
Un quasi sans faute pour ce module, puissant et qualité sonore au top (je ne m'étendrai pas sur ce sujet, pas assez d'expérience et ne maîtrise pas les termes techniques), excellent système de refroidissement.
Je vais quand même lui enlever une étoile à cause du mod à faire pour pouvoir lui fournir un signal asymétrique : nécessite de souder des OPAs (non dispos sur le site à part sur adaptateur DIP8 et donc à dessouder au préalable), et fait sauter la garantie du module.
Des sockets DIP8 auraient été un gros plus.
