Chip swap question

I've got a Bottlehead Quicksand that employs a TPA3122 chip. I also have a TPA3125 chip. Aside from a couple of different inductor and polarized capacitor values, the Texas Instruments datasheets for the 2 chips are nearly identical. But the TPA3125D2 is advertised as a higher quality chip, albeit with less power.

So I am tempted to drop the TPA3125 in to see what's what.

Can anybody advise me if this is a bad idea? I do not want to harm anything. But I am curious.
