3E Audio PFFB

Malanced Class D Amplifier Module TPA3255 BTL 2x260W

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

The 3E Audio 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 : TPA3255 Measurements and feedbacks
Hi all,

This module is made in the state of the art rules ! check the Audio Science review Thread (daniboun) for measurements. Very well made and reliable TPA3255 module. Fully differential, SE mode could be supported by adding new OP amps only. So far : this module is neck to neck with the Topping RA3/PA5 with a 105DB Sinad : THD+N in 4Ω / F = 1kHz, Po =5W = 0.0007% .
I really recommend it !

Excellent quality
I had to wait for quite some time to get this modules but they are worth waiting. The modules are (compared to a lot of other TPA3255 modules) of excellent quality. A large milled heat sink with tapped holes to fix the modules in an enclosure, high quality parts, precisely aligned (SMD)components, and larger/heavier components fixed with an elastic adhesive. I haven't tested them yet but I am quite confident that they sound as good as they look.
