Abacus TPA3255 Power Amplifier

This amplifier is based on a modified 3e-audio TPA3255 board.
It features switchable Balanced / RCA inputs, remote trigger, reset (with fault LED).
According to TI the power output is 2x315W @4ohm, and 2x150W @8ohm

The amp sounds extremely good - it is absolutely quiet, smooth, powerful, dynamic, and resolving. It throws huge soundstage.

Description:
TPA3255 is a high performance class-D power amplifier that enables true premium sound quality with class-D efficiency. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra-HD). This technology allows ultra low distortion across the audio band and superior audio quality. The device is operated in AD-mode, and can drive up to 2 x 315 W into 4-Ω load at 10% THD and 2 x 150 W unclipped into 8-Ω load and features a 2 VRMS analog input interface that works seamlessly with high performance DACs such as TI’s PCM5242. In addition to excellent audio performance, TPA3255 achieves both high power efficiency and very low power stage idle losses below 2.5W. This is achieved through the use of 85 mΩ MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
