Better quality? This stuff is designed to make things go BEEP, QUACK, BRRRRRR, DING DING DING or maybe some low level announcement stuff. Definitely not Hi-Fi.

Louder? Loud any sound quality walk into different directions.

Hey, this stuff costs literally pennies, cents, rupees. Mail order both and some other more and try them on a breadboard.

In what way? It's similar to the 'Amplifier with bass boost' circuit in TI's data sheet. Only there is a capacitor missing next to the 10Ohm resistor from pin 5 to ground.

That. Its putting a DC load on the amp, The 388 is only specced with an AC coupled load, run single-ended.
