I'm new to the realm of DIY audio, soon I'll be making a pair of speaker cables and interconnects. I've also started to toy with the idea of making my own 2 channel amp. I'm really only looking for something in the 20-50wpc range. Are there any high quality/decntly priced DIY kits out there? I'm realistically looking at around $500, but not sure if that's too low a figure. I have a fairly good understanding of electronics, so anything that has a fairly logical approach too would be no problem, not to mention I have 3 people in my family who are electricians/electrical engineers..thanks for any advice
