50W Hi-Fi amplifier by TDA7294
The TDA7294 is a Hi-Fi amplifier and can give 100W RMS but with 10% distortion. Supplying 30 Volts you can have 50 Watts RMS with 1% distortion. Frequency range start at 16Hz and can reach 100KHz. Make sure you are using good heatsink. The chip supports mute function as well. A symmetrical 30V power supply is all its need to power the unit.

LM3875 Non-Inverting Gainclone Amplifier
That is, a single integrated circuit based on an operational amplifier (op amp) on a single substrate of silicon. The LM3875 is the ?weapon of choice?. This great chip, is a little larger than the size of a thumbnail and can deliver up to 56W RMS continuous with 100W peaks and it can do this at 0.05% distortion! Because they are DC amplifiers (DC coupling right through the amp) they can go all the way to 400kHz!

Amplifier Class AB Hi-Fi 70W by MJ15022 , MJ15023
This project considers the development of a 70W Hi-Fi Power Amplifier for use as part of a Hi-Fi separates music system. The design is a fairly simple circuit topology, which is easy to understand and the author believes that the finished result sounds very nice indeed. The web posting is developed from an original design document available in pdf below. The detailed design issues are discussed in the pdf, while this posting discusses the more practical issues involved in producing the amp.
