SACD titles released by Hong Kong Sony are generally made in the EU. In recent months, HK Sony started releasing single-layer SACDs and those are made in Japan.
Single Layer SACDs can be made on a DVD pressing line, while Hybrid SACDs require special presses that handle Hybrid SACD, DVD and CD.
So it's tempting for the record labels to issue Single Layer SACDs since the manufacturing cost is less and there are more places where they can be made.
