Seems Sony/Columbia like to sabotage their own technology/formats. I remember when that Sony SACD player came out. I was flabbergasted that it was so expensive and 2 channel only. To me the exciting thing about SACD was 5.1 channels of HI-Rez audio. I waited for the multi-channel units to appear. Of course the Sony/Columbia SACD's were 2 channel single layer. I just could not believe they undermined their own format. Interestingly, they did the same with SQ quad. They spent many advertising dollars on the advantages of SQ and its stereo compatibility and then they put put dual inventory of quad and stereo LP's. I have wondered if they just put out the compatible quads only, if the format would have faired better. Same with SACD, they should have released a multi-channel version of discs and players. Makes one wonder about companies that ignore their own advertising claims. Unbelievable!
