Hello I have to state this right now too get this off my chest. First I have a DR-9 amp two great amps sound wise, built, along with excellent reliability? Now the question is DR-9 vs Sunfire well here is my warning I purchased a sunfire reference amp back in the yr of 1998. It was a beautiful looking beast dual power cords blue light and all. A week into playing this Magestic beast " I thought" was playing some vinyl and than silence found out blown transistors sixteen this from a tech. Not Sunfire tech you see they did not want to even look at the amp their service was nothing short of a disaster. I will never purchase another Sunfire product again. Classe Fabulous always responed to email's and was able to receive two rocker switches for two DR-9 amps for nothing. So be warned they Sunfire have alot to answer to as far as service is concerned.
