Amplifier Upgrade - Replaced TDA 7851 with Pioneer MOSFET PA2030A on Eonon GA2171S

Unless you did a blind A/B testing, or use a calibrated microphone to measure frequency response, anything you hear can be procebo.

Anyhow, I saw a post somewhere where someone added capacitors for bootstraping and what not, that would most likely improve the sound vs swapping the IC alone.

It also gave the car another 100HP....

Yes, and according to the datasheet, the gain ID so little it is unlikely to be perceived. A bit like oxygen free cable.
