audioguru Well-Known Member Most Helpful Member Jan 6, 2008 #4 Semiconductor manufacturers have hundreds of simple and good sounding amplifier ICs. Most "amplifiers" from the Techlib site don't have negative feedback from their output so they will have horrible distortion. I simulated a Techlib amplifier. At a low output level it has crossover distortion. At an output of a whopping 0.17W its distortion is horrible. Attachments Techlib amplifier.PNG 54.1 KB · Views: 138

Not only that but some of their circuits use crappy op-amps like the LM358.
