I'm thinking to made a QS decoder for listening classical records. I'have some schematics of 90º phase shift..but... It's reasonable add a resistor blend circuit??
I'ts possible add a logic circuit with discrete components??
Please, I need schematics for these options..

Several users here have found that DPL II has a settings that allows for a correct QS decoding. Probably this is the best option at present day, since Sansui Variomatrix are very expensive.
Maybe someone can give you the good DPL II setting for QS.
 
I'm thinking to get a Sony STR-DE 585 receiver (with DTS, DD and Prologic II). It's a good choice for listening QS records?
