We can see that in Korea, music lovers are also taken by the AMR sound as illustrated by the AM-777:
"The consumer retail price is 5.5 million won which contrasts with the fact that this is a one in ten thousand amplifier. Since this is not a common and easily-made product, it is a little bit more refined than the other ten thousand amplifiers and is one for the heart. In particular, the amplifier's charming vocals and delicate musical tapestry is unfound at this price level. Using our Korean analogy, it is like trying to find the ideal porridge and I think I have found it."
