"When I considered my concepts, I went back to the starting point of analog sound as vacuum tubes. At the same time, I had a fateful meeting with late Mr. Shishido who designed a new tube circuit. We developed new products by trial and error, but we were blessed with wonderful chassis design and staffs.
Another blessing was we had many audiophiles all over the world who agreed with our concepts."
