Visiting Prof. Kaneta house.<\/p>\n

————-<\/p>\n

<NOTE>Mr. Kaneta had been a professor at a national university until his
\nretirement.
\nSo, we still call him as Prof. Kaneta with respect.<\/p>\n

—————<\/p>\n

From the next day of trial listening meeting, I went to Tohoku (North-East Japan). And I had an opportunity to visit Prof. Kaneta house.<\/p>\n

As you may know, his audio system is a large-scale 4-way system with using ceiling-mounted horn speaker for the bass sound.<\/p>\n

In my impression, his system sounds were very natural unlike its appearance. Each 4-way channel is mixed in the space without any incongruity. And it was like the sounds of full range speaker extended upper and lower.<\/p>\n

I listened jazz sources mainly at that time. It is vivid, and when sax-solo came in, I was soaked in the full of life mid-range sounds. Airy bass sounds beat out rhythm cozily along with it. It was very precious experience for me to know the sounds that he listened normally.<\/p>\n

I appreciate him for willingly accepting my visit.<\/p>\n

\n

As I heard, he adopted Shinichirou Ishii-sensei’s theory (the author of “Acoustics of listening room revised and enlarged edition”<\/a>) to his audio room base. And I was with the Shinichirou Ishii sensei unexpectedly in Tohoku the day before.<\/p>\n

Prof. Kaneta’s listening room was built long before. And it reminded me a story I had just heard from Ishii sensei: When he presented his theory at an academic conference or by book, almost no one cared about it. (Some inquires were made from outside of Japan and some people adopted his theory and built listening room based on it)<\/p>\n

The darkest place is under the candlestick should be the word for that because now I know Prof. Kaneta support his theory. And I did not know that until this time. Prof. Kaneta has a high opinion about him as he said that Ishii sensei was the only person who published on listening room acoustics clearly and rationally at that time.<\/p>\n

<NOTE>
\n“Sensei” is a Japanese honorific title, which is used for the person who has a specialized knowledge.<\/p>\n

\n

Prof. Kaneta said he does not use fixed-amps but he always adopts new models. This is because of his simple logic that new amp should be the improved and better one, so “if we want to hear the best sound, we should use the most updated one.” But, it is difficult to create 4-way 4-same-amp environment at all time. So when it is impossible, we have to choose different amps to some extent as current his system is (shown below). Even though he said up-to-date amp is the best, I felt he mixes different amps in the range of his taste so I thought this is good. It has been considered that the necessary requirement to success multi-amp-system is to use same amp. But now I realize it is also good to choose different amps in a system.<\/p>\n
