LM3886 Done Right Kit Headphone Amp Siegfried Linkwitz argues that theThe LM3886 Done Right extracts as much performance from the LM3886 chipamp as possible without using error correction and other tricks. It delivers 65 W into 4 at a higher performance level than specified in Texas Instruments' LM3886 data sheet! The stellar performance is achieved through proper decoupling, a well engineered PCB layout, and genuine quality parts. The LM3886DR circuit board is made in Canada and the parts are sourced from authorized
