PAULA TSUI had albums on Phillips, CBS/Sony so it made me wonder if these were pirates as she also had releases on
Man Chi Records Co.
Then there are
Leico Record &
Haishan Records out of Taiwan that have some legitimacy with SQ, QS and 4 Channel notations of Taiwan artist that I have wondered about. I have about 500 to a thousand listings of different Taiwan recordings that could be legit or Pirate but not knowing the Artist and label history, etc. I have not come to a conclusion.
I have no idea if any of these that mention 4 channel are quad and I suspect it was just a marketing ploy and they are not encoded but Quad hardware under different names than we are familiar with were sold in Hong Kong & Taiwan.
Could it be that 4 channel refers to the number of tracks the master was recorded on?
