Can this board replace fosi v3 mono to save me money?

Will this board be better than an amplifier like v3mono? The purchase only costs 14 dollars

I found such a board on a website in China. It is very cheap, only 13 US dollars. Its introduction mentioned that it integrates feedback design and error correction. Could it have pffb technology??
This is its introduction:


The TPA3255 is a high-performance D-class power amplifier from TI Texas Instruments, featuring D-class efficiency and delivering truly high-end sound quality. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction. This technology enables the device to maintain ultra-low distortion throughout the entire audio frequency band while presenting high sound quality. This device operates in AD mode. When THD is 10%, it can drive up to 2 315W4R loads and 2 150W(unclipped power)8R loads at most. In addition to its outstanding audio performance, the TPA3255 also features two major advantages: high power efficiency and ultra-low idle power loss (less than 2.5W).



My question is whether this will be similar to the metrics of fosi v3 mono or 3e audio. In that case, I can save a large amount of money

As PFFB is a selling point it seems unlikely that they would have it but not mention it.

Again unlikely - or they would be showing the measurements to demonstrate it. At best you'll be getting A07 performance, and likely worse.

Some time ago QuantAsylum tested a cheap TPA3255 board and the TI evaluation board (without using PFFB). The cheap one performed significantly worse.
