Well-known vinyl lover Tony Bolton of HiFi World penned a very complimentary review of the AM-777 Premier Class Pre-Main amplifier. The AM-777’s character was neatly summarised by his narrative…”it didn’t try to force the listener to take notice, but laid the music out on display, then seemed to step back and let the tunes speaker for themselves.”

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."
