You have a PM.Just a quick update for everyone. I bought an SX-1280 and an SX-1980 and had them both upgraded by a fellow from Dripping Springs Texas. The SX-1280 was flawless. The SX-1980 had multiple faults. I had to have it serviced by a fellow in Knoxville (Terry DeWick). It is now flawless and sounds superb. Thanks again to everyone for their help and advice. Anyone out there have any information on how I may contact the designer of my TF-2000's? I believe his name is Steve Eberbach. Thanks again.
