It is infesting how the FM glory is pushing aside my interests in other media. Anyhow after many experiments and “tweaking” my Experiential TU-1X not juts equal to the original in Sound but suppresses the original and it has became my reference recording source (I my post some examples of the records from the last week). So, I am very glad that I did not get rid of my Experiential Sansui after the initial unsuccessful attempt.

However, the Sansui TU-1X tail is not over.  With all simplicity and un-sophistication the TU-1X it turned out to have an amazingly good sounding multiplex decoder. I am experimenting now with front-end with IM section that is more capable then Sansui TU-1X but it is VERY hard to beat the TU-1X stereo decoder. The basic battle now is between the old switching multiplex and the newer PLL decoders. Sansui TU-1X uses the HA-11223W chip to extract stereo from 19kHz. It is $3-worth chip but it so beautiful sounds!!! If my other method will not be able to defeat the TU-1X’s stereo decoder then I will use other TU-1X’s juts as the multiplex stereo extractor and output stage. It is too big and probably it would not be difficult to rebuild it from scratch but I do not want to do it myself. If any of you know an interestingly sounding PLL stereo decoder around the HA11223W then let me know. For the time being I will be using the F2972 board of my Sansui TU-1X…

Theoretically it would be a good idea to switch TU-1X’s output section to work delectably from internal or from externals sources but would like in no way to degrade the original TU-1X sound form the internals IM section. Perhaps in the future is the Sansui will be the uncontestable multiplex extractor winner then I will go to this direction…
