ok since this is the only TPA3255 /PFFB video on YT I leave this here. No offence ok. Nice job. But as TI's own figures show, the result is not worth the effort. Yes, it makes the damping factor higher. But the absolute numbers are so low and there is like 0.00X redection in distortion in higher frequencies. And gain is less. Even if TI issued this PFFB paper, I don't think they are that much convinced themself. Think the 3255 was designed from the start with the integrated pre-filter. And it's just a fine chip as it is, for almost no money. For something really noticable better get Hypex or Purifi.
