It was quite phenomenal FM program this weekend in Boston. I was running it mostly off the Sansui tuner and again and again I was stunned how good stereo imaging with this beast. Since I am in progress of building up the requirements and specifications for my own reference decoder I was thinking about the TU-X1’s stereo results. Wondering about the TU-X1’s stereo look at the TU-X1 service manful and noted a strange thing. The TU-X1’s frequency response was from 20Hz to 18kHz. That was kind of strange as usually all stereo tuners are marked up to 15Hz as they need to run minus 40-70dB filer at 19kHz to kill the pilot signal. I begun to look deeper into what Sansui does in TU-X1 and I found something that would explain it.
