If you actually want to build something, the easy route is to use an IC. Texas Instruments has lot's of audio ICs and they have application notes and schematics. Some designs are super-easy, especially if you are building a low-power or headphone amp, and you can "automatically" get good performance.
Analog Devices also has plenty of app notes.
If you can get your hands on an old copy of the Linear Applications Handbook from National Semiconductor, it's definitely educational, too.

Hey, welcome to ASR.
Well there is a DIY sub-forum here;
DIY Audio Forum
Let us know what you have built yourself that is cool and fantastic.

The Ti LME49600 is used in the Atom Amp+ and it is a nice layout for a experienced or beginner project.

Thank you for all the suggestions. I am really interested in discussing an existing design I did recently, already prototyped and tested. It is a 100W class A/B amplifier using IRP240/IRP9240 MOS power devices, and uses a novel (to my understanding!) bias scheme for the power devices.
Post a schematic over in the DIY forum section. Several of us there do our own designs and are happy to discuss them.
It is an equivalent of much older BUF634. My implementation of BUF634 is here:
Audio Buffer – unity gain link stage/headphone amp with ultimate output drive capability
Audio Buffer – unity gain link stage/headphone amp with ultimate output drive capability I have been using a similar circuit in measuring instruments for HV tests since 1980's and later decided to use it for audio, for its excellent output drive capabilities. I described the reasons in my web...
