Wayne; I too have had chip based recievers including NAD and the old Yamaha cr series. My brother-in law has it still. I don't rememmber them sounding as good as these little chip amps. I am going to ask him to let me try it again but I still don't understand why there would be this difference. Is it due to the construction of the chip; or different materials or implementation? I know it isn't my imagination because I still have the NAD and it most assureadly doesn't equal this little GT kit. What can it be? Shorter signal path? Thanks, J.R.
