We get posts nearly every day asking which power amp to buy, which is the "best", whether to buy one model versus another, etc. So I wrote this article as a way of helping beginners (and maybe some experienced players too) figure out which power amp will be a good purchase. http://www.ovnilab.com/articles/poweramp.shtml Again it is mainly written with the non-expert in mind, so I have kept some things simplified. If you see anything in there that could be explained more simply or elegantly (while remaining factual), please do let me know, and offer suggestions! My aim is to make it all more understandable. I'll also welcome technical corrections, if you see any--but be advised that I am skeptical about what some people will consider "corrections". You know how we argue here in Amps. Cheers!
