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 !
