I could almost swear that you can even create a class-D amplifier with the ATTiny85, with a clock rate of ~15kHz.

Obviously it's not going to be ideal for an audiophile, but the quality is not too shabby. A fun project for those curious.

Still, stick to off-the-shelf class-D amplifiers, such as the PAM8403.
