A&M had originally announced five albums that were slated for QS release in the US, including "A Song For You", from the Carpenters, and "Come From The Shadows", from Joan Baez. The latter was the only one of the five to hit the stores. The ad went on to say they were using an improved vinyl formulation for the quad releases, because in quad, "when the record pops, the whole room pops". I grabbed the Joan Baez album as soon as I saw it, and was very pleased with its sound. I had a Sansui QS-01 decoder connected to my system and, considering how good their first effort sounded, I was bummed that the others got tabled.
